MULTIPLE BLOCK SLIDING MEMBER

FIELD OF THE INVENTION

The invention relates to the field of the acceleration of material, in particular a stream of granular or particulate material, with the aid of centrifugal force, with, in particular, the aim of causing the accelerated grains or particles to collide with an impact member at such a velocity that they are crushed, but other possible applications are not excluded.

BACKGROUND TO THE INVENTION

A stream of particle material can be accelerated with the aid of centrifugal force. With this technique the material is fed onto the central part of the rotor that rotates rapidly about a vertical axis of rotation and is provided with accelerating members, which accelerate the particle material with the aid of centrifugal force along a radial directed sliding face, to be thrown at high velocity from the rotor to collide with an impact ring that surrounds the rotor to be crushed; such impact crushers are known from US 4,090,673, and are called VSI for Vertical Shaft Impactor. The VSI is popular because it is simple and produces very good quality crushed product with cubical shaped material that is specified for asphalt and concrete.

The accelerating members most widely used, comprise a sliding member and an attachment member, and are separately positioned on top of the rotor, a distance away from the axis of rotation, hence the name open rotor, which sliding members are known from US 4,174,814 provided with a stub member that extends from the back face and fits the attachment member, providing an attachment arrangement for firm attachment of the sliding block can firmly to the rotor, secured with a lock pin that has to be removed for exchange, but gets often stuck, hindering exchange of the so-called stub shoe. Sliding members can also be attached with bolts, and are known from US 6,070,820, which is also rather complicated.

Sliding members can also be centrifugally locked to the rotor, which provides for much easier exchange, and are known from, for example, WO 2010/008273, which is in name of applicant, which reveals a very simple symmetrical V-shaped accelerating member provided with two sliding faces, one for each direction of rotation, and is pivotally attached to the rotor only along the bottom side of the sliding block - called pivot shoe. PCT/EP2013/000271, which is in the name of applicant, reveals a sliding block member - called clip shoe - that is provided with two open locking chambers stretching along the bottom side and along the top-side, providing an attachment arrangement for centrifugal locking to the attachment member, and can also be configured symmetrical which makes it possible to centrifugally lock two shoes to each side of the attachment member, for two way operation of the rotor.

The known shoes have to be frequently exchanged because of wear, with abrasive feed material often every day. The heavy weight - typically 40 to 42 kg - possible problems with the lock pins, and the narrow working space on the rotor, makes handling very difficult and dangerous, and can induce serious injury to the operator, in particular musculoskeletal disorders, which are the most common type of occupational ill health. Manually assisting mechanical lifting and installing and attaching of these heavy shoes, but mechanical lifting devices have proven not to be effective, taken into account the limited working space on top of the rotor. Moreover, final positioning of the shoes still requires manual handling, lifting and sliding, of these extremely heavy shoes by the operator, and things get worse when a shoe becomes stuck on top of the rotor or when the attachment arrangement does not properly fit or has become damaged, or the shoe is stuck in the attachment member.

This can be prevented by limiting the handling weight according the official international recommendations by health authorities, which restrict the maximum weight that may be manually lifted or manually handled by a plant operator to 25 kg or 55 lbs. Such lighter shoes cut service time to half, making these type of crushers much less competitive, as the industry wants longer service times to reduce down time. VSI manufacturers are therefore reluctant, but to have to accept that lifting weight has to be reduced to a healthy level, that is 20-25kg.

The heavy weight shoes generate extremely high centrifugal forces - typically 150kN to 250kN - which, in turn, generate very high stresses in shoes and the attachment construction that transfers the centrifugal force to the rotor, consuming typically some 10% (and more) of the shoe weight, and require extremely strong, and often complicated attachment members for transfer of the centrifugal force to the rotor, which further complicates exchange. Hard metal, like tungsten carbide, is applied to construct the sliding faces that present very high wear resistance, and hard metal chips attached to the shoe with bolts are known from US 4,871,119, and tablets can be constructed with hard metal inserts, presenting a sliding face part, to be connected to the accelerating member, are known from US 2008/0135660 and EP 2 545 996. Tungsten carbide is, however, very heavy, substantially increasing the weight of the accelerating members, increasing handling weight, and increasing the centrifugal force, generating very high stresses in the attachment arrangement; which hinders hard metal applications with sliding members.

Weight can be saved with shorter shoes, providing shorter sliding faces, known from US 5,184,784 and US 6,070,820, but these shoes provide less effective acceleration, reducing impact intensity, and are therefore not practical.

Another known way to lower lifting weight is to use sliding members with a layered construction, and are known from US 4,347,988, US 4,355,769, and EP 2524996 with layers that stretch behind each other, and from US 4,373,679, with layers positioned on top of each other, but the known layered constructions have proved not to be practical, and not limit handling weight.

Another known approach is accelerating members designed for two-way operation, which acceleration members are symmetrical to the radial plane from the axis of rotation, providing two sliding faces, one for each direction of rotation, increasing rotor service time accordingly.

FR 2 182 416 reveals an open rotor of rather complicated design, provided with an accelerating member for two-way operation, of four components, centrifugally locked to the rotor, with the aid of a separate securing tool at a location underneath the rotor, presenting a sliding face, of more sliding face parts, for each direction of rotation, that is not regarded practical. US 5,497,951 reveals a semi-open rotor of rather complicated design, provided with an accelerating member provided with two shoes, mechanically attached with heavy bolts to each side of the attachment member with the aid of a cover top plate, together with a separate inner face member for protection of the holder. The known symmetrical configuration with two shoes divides the weight that has to be lifted over two shoes; but are not practical to lower handling weight, because the service time of two 20kg shoes is significant lower than obtained with one 40 kg shoe. US 7,051,964, which is in the name of applicant, reveals several symmetric configurations for V-shaped acceleration members, both one-piece and two-piece, providing one sliding face for each direction of rotation, intended for synchronized two step acceleration; applied as sliding block member, it is noted that the inner side is not designed to pick up material for centrifugal acceleration, and the configurations can only be applied when the acceleration members are provided with a strengthening member, here a bimetal configuration, and the configurations are therefore regarded not practical for centrifugal acceleration by sliding. Similarly, WO2004/002630, which is in name of applicant, reveals another V-shaped symmetrical strengthened - bimetal - configuration of an impact/sliding member of two blocks, but casting of bimetal members is rather complicated and expensive.

Restriction of manual handling weight has become a global problem. More than a third of all industrial accidents every year are caused by manual handling of loads, in particular by too heavy lifting. Rather than asking employees to lift too heavy items or bending down and reaching up to do a task, employers can reduce the risk of injury to their employees and boost productivity by limiting the lifting weight to 25 kg, and provide easy handling.

However, as explained, known sliding members have to be 40kg to be competitive, that is provide efficient life time; add to this, that known attachment arrangements require very heavy constructions and may be rather complicated for exchange, that the known rotors presents narrow working space, and, that mechanical lifting devices are not effective.

Therefore, the problem that has to be solved is to find an alternative and more convenient constructional design of the accelerating member of very simple design, which are effective, reduce handling weight, can be easily exchanged, reduce the centrifugal force, and may easily be manufactured. AIM OF THE INVENTION

The aim of the invention is to solve this problem by providing a rotor of the open type, provided with accelerating members that do not have the shortcomings listed before, or at least displays these to a lesser extent; that is, an open rotor provided with accelerating members of simple design, which are effective, reduce handling weight, reduce the centrifugal force, and are easy for exchange.

More specific, the principle aim of the invention is to provide an accelerating member provided with a sliding block member of simple design for either one-way or two- way operation of the rotor, which may be easily manufactured, and significantly reduces the handling weight, in particular the weight that has to be lifted when the sliding block member has to be exchanged, and can be provide with more simple attachment arrangements, that is, for example, from typically 40 kg to a healthy 20-25kg, and lower weights are possible, without affecting service time and accelerating performance of the rotor, and essentially without affecting the amount the wear material consumed per tonne processed material, which means, without affecting the wear costs - and even allows for a configuration that up to redoubles rotor service time at lower wear costs; and at the same time may reduce the centrifugal force.

Another aim of the invention is to provide very simple arrangement for attachment of the sliding block member to the rotor, for very easy and quick exchange, in particular with the aid of a centrifugally locking arrangement, possibly with the aid of and/or interaction with another sliding member, avoiding the need for separate mechanical locking and/or securing arrangements and/or tools;

Another aim to configure the accelerating member, possibly composite configurations, and to choose the construction materials, such that lifetime is extended.

Another aim of the invention is to provide an attachment member that is better protected, limiting damage during service, and may be separately exchangeable - and even to avoid damage to attachment arrangement completely, providing a permanent rotor assembly.

Another aim of the invention is to provide an accelerating member that applies more wear resistant construction materials that extend lifetime in significant way.

This Brief Summary is provided to introduce simplified concepts relating to the aim of the invention, which is further described below in the Detailed Description. This summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.

The aims of the invention are achieved by providing a rotor of the open type, for either one-way and two-way direction of rotation, with accelerating members comprising a sliding block member and an attachment member, wherein the sliding block member is of at least two sliding block parts, an inner sliding block part and an outer sliding block part, each provided with a sliding face part, an inner sliding face part and an outer sliding face part directed, facing the same direction of rotation; the sliding block parts, each of at least one part, to be separately attached to the rotor, with the aid of at least one attachment member, of at least one part, possibly with different attachment arrangements; arranged next to each other in an essentially radial direction, the inner sliding block part closer to the axis of rotation than the outer sliding block part, separated along a separation joint, transversally directed to the radial plane from the axis of rotation, creating a radially arranged multiple block sliding member, of at least two sliding block parts; the sliding face parts, aligned in an essentially radial direction, stretching in a continuous way into the direction of the outer edge of the rotor, separated by the separation joint, creating a radially aligned multiple sliding face, of at least two sliding face parts, facing the same direction of rotation; creating a radially arranged multiple block sliding member, dividing the weight of the sliding block member over at least two sliding block parts, limiting handling weight, limiting the centrifugal force generated by the sliding block part, essentially, without affecting acceleration performance;

The accelerating member according the invention allows to be configured symmetrical to the radial plane from the axis of rotation - of two, three, four, or even more sliding block parts - providing two radially aligned multiple sliding faces, each of at least two sliding face parts, for each direction of rotation, for two way operation of the rotor, effectively redoubling rotor service time;

The accelerating member according the invention allows for attachment of the sliding block member, along the back-side of the sliding block member, only along the bottom- side, and along the bottom- side and the top- side;

The accelerating member according the invention allows for very simple attachment arrangements for very easy exchange - in particular with the aid of centrifugal locking arrangements, possibly, with the aid of and/or interaction with at least one other sliding block part, avoiding the need of any separate mechanical locking and/or securing tools for attachment of at least that sliding block part, the attachment member of one part, or of more parts, separately associated with the sliding block part;

The accelerating member according the invention allows for the attachment member to be separately exchangeable in case of damage, avoiding complete retrofit with a new rotor table when only one attachment member has become damaged;

The accelerating member according the invention allows for the application of an adaptor, such that the sliding block parts are indirectly, separately exchangeable, attached to the attachment member of an existing rotor;

The accelerating member according the invention allows for a section of the separation joint to stretch into a radial direction, the interaction created through direct contact between two sliding block parts along said radial section, creating a contact area for transfer of contact force, generated by centrifugal force, in transversal direction, to reduce stress in at least one of the sliding block members;

The accelerating member according the invention allows for the sliding block parts to be positioned a distance apart, creating an open separation joint, at least along the transversal section of the separation joint, avoiding transfer of forces in radial direction, and the invention allows for the transversal section of the separation joint to stretch, at least partly, from the sliding face into a direction at equal radial distance from the axis of rotation and/or a direction closer to the axis of rotation, avoiding accumulation of particle material in the open joint;

The sliding block parts according the invention are constructed of one or more construction materials, that may include a hard iron based alloy, metal, including hard metal parts, and other highly abrasive resistant materials, for example, that the sliding face and other exposed parts of the accelerating member and the rotor are partly constructed of highly abrasive material, to increase lifetime - for example ceramic inserts, and/or other types of wear resistant inserts or inclusions or linings, and/or hard metal inserts or inclusions, for example cemented carbides, like tungsten carbide or titan carbide, and the invention allows for application of synthetic materials, like plastic composites and rubber; and the invention allows also the sliding face to be configured with open cavities and chambers, possibly stretching along the separation joint, and to be provided with a profile to affect sliding and acceleration behaviour, such that longer wear life is obtained - in this respect, the invention allows for the sliding block parts to be configured of two, or more, parts, for example sandwiched construction parts, possibly constructed at least partly of different construction materials, the sandwich parts firmly connected or separately attached to the attachment member, either fixedly, possibly with the aid of locking tools, or centrifugally locked;

Figures 2, 4 and 4, show and explain, the principle of the invention, that is, a translation, here, of the sliding block member of prior art (11), achieved by splitting (51) the sliding block member of prior art (11), along a separation joint (38), that is transversally directed to the radial plane (39) from the axis of rotation (0), in two sliding block parts (29)(30) - and the invention allows for splitting (51) in more than two sliding block parts (29)(30) - creating a simple radially arranged multiple block configuration, or, the radially arranged multiple block sliding member (40) according the invention, comprising at least two separate sliding block parts (29)(30), with reduced handling weight, for easy and safe exchange of the sliding block parts (29)(30), where the splitting (51) in two sliding block parts (29)(30) does not affect sliding acceleration performance, because the single block wear pattern (52) and the multiple block wear pattern (53), are essentially similar, that is, not affected by the separation joint (38) between the sliding block parts (29)(30).

Not shown here, the invention allows for the separation plain (10) not to stretch along a straight plane, for example bended, or discontinuous partially stretching in a more radial direction, and the invention allows for the continuous sliding face (31)(34) to be bended, in either forward or backward direction, and to be provided with open sliding chambers, possible stretching along the separation joint, which fill, at least partly, with particle material, creating an at least partly autogenous sliding face; and the invention allows for the sliding block parts (29)(30) to be positioned a distance apart, creating an open separation joint (54), as will be discussed later.

Figure 5, shows, diagrammatically, the stress distribution generated by the centrifugal force (56) in the accelerating member (5) of prior art, and, figure 7, for a accelerating member (6) according the invention.

As indicated in figure 5, with the accelerating member of prior art (5), centrifugal force (56) generates a centrifugal vector (56) stretching from the point of gravity (57) of the sliding block member (11) along the straight line (58) from the axis of rotation (0), and does not cross the support side (59), generating a turning force (61), which means that the sliding block member (11) wants to turn (60) away from the support side (59), as illustrated in figure 6, and the attachment arrangement (13) has to prevent this. The turning force (61) can be reduced, by positioning the support side (59) in a forward direction (62), that is, into the direction of rotation (3) such that the centrifugal vector (56) shifts more into the direction of the support side (59) - typically, with the accelerating member (5) of prior art, the forward angle (62) of the support side (59) is 30-40 degrees. Positioning at a less flat angle increases the turning force (61) dramatically, such that it cannot be contained by the attachment arrangement (13), when the sliding block member (11) breaks away (63). Furthermore, the stub member (24) transfers the radial force (64), generated by the centrifugal vector (56) and acting along the support side (59), to the attachment member (13). Part of this radial force (64) can be transferred, by providing the sliding block member (11) with a pressure side (65) that presses against the inner edge (66) of the support side (59) - but typical with this attachment arrangement (15), the radial force (64) is completely transferred via the stub member (24).

As indicated, in figure 7, essentially the same stress distribution develops, here, with for the sliding block parts (29)(39) according the invention, provided with similar attachment arrangements (15), which means that both sliding block parts (29)(30) want to turn away (67)(68) in the same direction, away from the attachment member (14), that is into the direction of rotation (3), under influence of the inner centrifugal force (69) and the outer (70) centrifugal force; but generate significant lower turning forces (69)(70) in the sliding block parts (29)(30), compared to the sliding block member (1 1) of prior art. For example, the centrifugal force (55) generated with a one piece sliding block member (1 1) of prior art, weighing 40 kg, installed on a 1000mm rotor, is typically in excess of 150kN; and with the radially arranged sliding block member (12) according the invention, about lOOkN for the outer sliding part member (30), weighing about 20kg, and about 50kN for the inner sliding block part (29), weighing also about 20kg, which strongly reduces turning forces (69)(70) in the sliding block parts (29)(30), and the stresses generated, here, in the stub members (33)( 36) and in the attachment members (42)(46).

The separation joint (38) stretches, here, from the back side (71) of the multiple radially arranged sliding block member (40) into a direction (72) closer to axis of rotation (0); which means that the rotating outer sliding block part (30) hinders movement of the rotating inner sliding block member (29), that can only move inward, that is in the direction (72) of axis of rotation (0); which means, that the sliding block parts (29)(30) are in contact along the transversal separation joint (38), which in turn means that the force (73) on the outer attachment arrangement (46) increases. This can be avoided by positioning the sliding block parts (29)(30) a small distance apart, creating an open separation joint (54), that prevents transfer of force from the inner sliding block member (29) to the outer sliding block member (30). The invention allows, also, for the transversal separation joint (38) to stretch, at least partly, from the sliding face (31)(34) into a direction at equal radial distance (74) from the axis of rotation (0) and/or in a direction (75) away from the axis of rotation (0), avoiding accumulation of particle material in the open separation joint (54), which also may ease detachment of the inner sliding block part (29), that now becomes self loosening.

As indicated in figure 8, diagrammatically, the opposite contact forces (83)(84) can be applied to reduce the forces (73) that builds up in the outer attachment arrangement (15), generating the inner turning (86) and the outer turning (87); therefore, a section (46) separation joint (38) may be directed in a radial direction, for example by providing the outer inside block side (30) with a stub member (77), and the inner outside block side (29) with a stub opening (80) that fits the stub member (77), creating a radial contact area (82), such that a significant part of the inner centrifugal force (69) is transferred via that radial contact area (82) to the outer sliding face part (30); this inner contact force (83) is opposite to the outer contact force (84), which means that the net force acting the outer attachment arrangement (46) is significantly reduced; and transferred to the inner attachment arrangement (42), where stress is lower.

Figures 9 - 11 show, diagrammatically, a second configuration of the composed accelerating member (90) according the invention, for one-way operation, where, the sliding block member (92) (stub shoe), is split in two sliding block parts (93)(94), stretching along the separation joint (95), each provided with a half stub member (96)(97), with the vertically directed pin openings (98)(99) stretching half open, such that, when positioned in the stub opening (100) of the attachment member (101), the half open pin openings (98)(99) present one closed pin opening (102), split along the separation joint (95). Note, that with this second configuration (90), it has to be avoided that the centrifugal forces generated by the inner (93) and outer (94) sliding block part, are completely transferred to the outer stub member (97); which is here achieved with the aid of an pressure strip (103) that protrudes from the inner inside block side (104), that presses the inner sliding block part (93) firmly against the inner standing hook edge (105) of the support plate (106) of the attachment member (101), transferring the centrifugal force generated by the inner sliding block part (93) largely directly to the attachment member (101). Moreover, the sliding block parts (93)(94) are, here, provided with sliding face layers (107) of a hard metal alloy, fixedly attached to a block plate member (108), creating sliding block parts (93)(94) with sandwich construction, which allows for a thinner, yet somewhat lighter, configuration, which limits the stress generated in the attachment arrangement (109) to certain extend. Figures 12 - 14, show, diagrammatically, a third configuration of the radially arranged multiple block sliding member (110) according the invention, essentially similar to the first configuration of the attachment member (6), where, the inner sliding block part (1 11) and the outer sliding block part (1 16) are attached to the attachment member (147) with different attachment arrangements (148)(149); the inner sliding block part (1 11) is along the separation joint (112) provided with a strip member (113) provided with a radially directed pressure side (114), fitting the stub opening (115) of the inner sliding block part (11 1), providing an inner attachment arrangement (148), for direct transfer of contact force from the inner sliding block part (1 11) to the outer sliding block part (1 16), such that the force acting on the outer attachment arrangement (149), or the outer stub member (118) of the outer sliding block part (116), is reduced; and the inner sliding face part (11) is firmly centrifugally locked with a centrifugal inner attachment arrangement (148), to the attachment member (147), with the aid of the strip member (113) and a hook member (119).

Figures 15 - 16 show, diagrammatically, a fourth configuration of the radially arranged multiple block sliding member (120) according the invention, here shown for application with shoe block members (117) and with sandwich construction (89) from the second configuration (90), wherein, the inner sliding block part (121) has to be positioned with the inner stub member (122) in the lock opening (123) of the attachment member (124), which inner stub member (122) is along the standing outer edge (125) configured angled outward, such that the inner sliding block part (121) becomes locked to the attachment member (124), once the outer stub member (127) of the outer sliding block part (128) is positioned in the lock opening (123), and secured with a bolt connection outer attachment arrangement (129), creating an inner attachment arrangement (137) that avoids the need of any separate mechanical locking and/or securing tool (129), for attachment of the inner sliding block part (121);

Figures 17 - 19, show, diagrammatically, a fifth configuration of a composed accelerating member (133), according the invention, detailed in figure 17, for one-way operation, wherein the inner sliding block part (130), detailed in figure 19, is centrifugally locked to the attachment member (131) with the aid of, or interaction with, the outer sliding block part (132), detailed in figure 18; the interaction created with the aid of a centrifugal inner attachment arrangement (134), through direct contact between two sliding block parts (130)(132) in the lock opening (142) and along the separation joint (136); the outer stub member (138) of the outer sliding block part (132) along the outer standing edge (139) provided with a hook member (140) that clamps around the outer standing side (141) of the lock opening (142), hindering the outer sliding block part (132) from turning away from the attachment member (131); and the inner sliding block part (130), positioned with the inner stub member (144) in remaining inner lock opening part (145) of the lock opening (142), hindering movement of the outer stub member (138) into the direction of the axis of rotation (not shown here), centrifugally locking the outer sliding block part (132); with the separation joint (136) stretching into the direction of the axis of rotation (not shown here), hinders the outer sliding block part (132) movement (146) of the inner sliding block part (130), away from the attachment member (131); centrifugal locking the inner sliding block part (130).

Figures 25, show, diagrammatically, a top view of a second configuration of a rotor (150) according the invention, for one-way operation (151), provided with a sixth configuration of the composed attachment member (152), according the invention, detailed in figure 20; provided with a radially arranged multiple block sliding member (153), detailed in figure 21, of two sliding block parts (154)(155), an inner sliding block part (154), detailed in figure 22, and an outer sliding block part (155), detailed in figure 23; with the attachment member (156) detailed in figure 24.

The attachment member (156), is, here, of one part, for attachment of both sliding block parts (154)(155), comprising, here, a support plate member (157), provided with a support side (158) that stretches into the direction of the outer edge (159) of the rotor (150) along the back block sides (160)(161) of sliding block parts (154)(155), and one lock opening (162) stretching throughout the support plate member (157), comprising, an outer lock opening part (163) and an inner lock opening part (164), the outer opening part (163) provided with, an outer edge (165) upper edge (166) and lower (167) edges, angled widening away form the support side (158), and the outer stub member (168) provided with edges (166) that fit the widening edges (165)(167), such that outer lock opening part (163) fits the outer stub member (168); the inner lock opening part (164), configured larger in vertical direction than the outer lock opening part (163), such that the outer stub member (168) can be inserted (170) in the inner lock opening part (164), to be slid (171) into the outer lock opening part (163), the angled edges (165)(166)(167) hindering the outer sliding block part (155) to break away from the rotating support side (158). The inner sliding block part (154) is provided with an inner stub member (169) that fits the inner lock opening part (164), such that the outer sliding block part (155) is hindered to move into the direction of the axis of rotation (0), centrifugally locking the outer sliding block part (155) to the rotating attachment member (156); the outer sliding block part (154) hindering movement of the inner sliding block part (154) along the separation joint (172) that stretches into a direction closer to the axis of rotation (0), and, the inner sliding block part (154) is along the inner inside block side (173) provided with an first angled hook member (174), that fits a second angled hook member (175) positioned along the inner edge (176) of the support plate member (157); hindering the inner sliding block part (154) to turn away from the rotating support side (158); centrifugally locking the inner sliding face part (154) to the rotating attachment member (156).

The radially arranged multiple block sliding member (153) is here centrifugally locked through interaction between the inner sliding block part (154) and the outer sliding block part (155), such that any separate locking and/or securing tools - like lock pins - are avoided.

Figures 26-28, show, diagrammatically, a second configuration of a rotor (180) according the invention, for one-way operation (181) - which is a preferred configuration for one-way operation (180) of the rotor (181) - provided with a seventh configuration of a composed accelerating member (182) according the invention; comprising a radially arranged multiple block sliding member (183) of two sliding block parts (188)(189), provided with a radially aligned multiple sliding face (184) of two sliding face parts (190)(191) directed into the same direction of rotation (181), wherein, the attachment member (185) is of two essentially similar separate parts (186)(187), detailed in figure 28, an inner attachment member (186), for attachment the inner sliding block part (188), and an outer attachment member (187), for attachment of the outer sliding block part (189), here, with essentially similar attachment arrangements (196),

The inner sliding block part (188), is provided with and inner sliding face part (190) and an inner outside block side (192), and the outer sliding block part (189) is provided with an outer sliding face part (191) and an outer inside block side (193; the inner outside block side (192) and the outer inside block side (194), stretching along a separation joint (195), as indicated in figure 30, directed into the direction of the axis of rotation (0) creating a radially arranged multiple block sliding member (183), provided with a radially aligned multiple sliding face (184) divided by the separation joint (195).

The centrifugal attachment arrangement (196) is based on PCT/EP2013/000271, which is name of applicant, to which reference is made. Each sliding block part (188)(189), detailed in figure 27, is provided with two open centrifugal locking chambers (197)(198), a lower locking chamber (197), stretching along the bottom block side (199) and an upper locking chamber (198), stretching along the top block side (200), each provided with a standing pressure side (201)(202), a lower pressure side (201) and an upper pressure side (202), directed away from the axis of rotation (0). Each attachment member (186)(187) is provided with two centrifugal locking plates (203)(204), a lower locking plate (203) and an upper locking plate (204), stretching from the support side (205) of the attachment member (185) into the direction of rotation (0), fitting the locking chambers (197)(198) for the attachment of the sliding block part (188)(189) to the attachment member (186)(187), such that the sliding block part (188)(189) is centrifugally locked to the attachment chamber (186)(187), avoiding the need for any separate locking and securing tools. The transversal thickness (206) of the attachment member (185) increases, here, in downward direction (207), creating a radially arranged multiple block sliding member (183) with an angled back side (208).

As indicated in figure 30, for the seventh configuration (182) to be functional, the following conditions apply: (1) the lower (201) and upper (202) standing pressure sides must stretch along the circle (209) from the axis of rotation (0), preferably, at least partly, form the support side (205) into a direction (210) closer to the axis of rotation (0), to prevent that the sliding block part (189)(190) will be thrown out under influence of the centrifugal force, and, (2) that the radial plane (21 1)(225) from the axis of rotation (0) through the point of gravity (212)(226) must cross with the upper (202) and lower (201) pressure sides of each sliding block part (188)(189), to avoid that turning forces develop, which may cause the sliding block part (188)(189) to brake away from the locking plates (203)(204).

The rotor (180), detailed in figure 26, is extremely simple, and requires only a connection opening (213) for each attachment member (185); here, the attachment member (185) presenting a simple hook member, cut out of a steel plate, inserted (214) from the bottom side (215) of the rotor (180) into the connection opening (213) welded (216) for firm attachment - the invention allows for other connection arrangements, for example, clamped between two rotor blades (not shown here), and figure 29, shows a second configuration of the attachment member (217) that can be inserted from the top side (218) of the rotor (180), to be centrifugally locked with the aid of a clamp block (219), that is than bolted to the rotor (180); which allows for easy and separate exchange of the hook attachment members (217), avoiding complete exchange of the rotor table.

The sliding block parts (188)(189) are placed on top (218) of the rotor (180), to be slid (220), to the attachment member (185), such that locking chambers (197)(198) fit the locking plates (203)(204). The attachment members (186)(187) are here completely protected by the sliding block parts (188)(189), leaving only the angled back side (208) and the top side (221) of the attachment members (186)(187) exposed, which means that damage to the attachment members (186)(187) is limited, mainly, to the top side (221), where damage is normally low, and to the angled back side (208), which angled position limits sliding wear and damage by rebounding and stray particles; but damage may occur when the sliding block parts (188)(189) are not exchanged in time and burn through; but contrary to the know open rotors, discussed before, the invention allows for easy separate replacement of the hook attachment members (185), as indicated before.

As is indicated in figure 26, the attachment arrangement (196) creates on top (218) of the rotor (180) wide open uninterrupted free space (222) between the composed accelerating members (182), which allows for instalment of at least five radially arranged multiple block sliding members (183) without hindering free passage (223) of the feed material towards and along the radially aligned multiple sliding faces (184); and provides space for even six (or more) radially arranged multiple block sliding members (183), increasing rotor ( 180) service time accordingly.

The second configuration of the rotor (180) according the invention, has the advantage that the attachment arrangement (196) of the sliding block parts (188)(189) does not require a stub member, which saves significantly on construction material, and the lock chambers (197)(198) present a further saving on construction material, without affecting performance.

Figure 31, shows, diagrammatically, third configuration of the rotor (230) according the invention, for one-way operation (231), provided with an adaptor member (229), for attachment of the sliding block parts (248)(249), according figure 27. The rotor (230) is provided with an attachment member (232) of prior art, from figure 1, provided with a first support plate member (233), provided with a first front side (234) facing the direction of rotation (231), stretching into the direction of the outer edge (235) of the rotor (230), a first back side (236) opposite of the first support side (234), and a lock opening (237), here, a stub opening, stretching throughout the first support plate member (233). The adaptor member (229) is provided with a second support plate member (238), provided with a second front side (239), a second back side (240) opposite of the second front side (239), and a connection member (241), here, a stub member, fixedly attached along the second backside (240) that fits the lock opening (237), for firmly connecting of the adaptor member (229) to the attachment member (232), with the aid of a connection arrangement (242), comprising, here, a screw member (243) and a connection plate member (244), such that the second back side (240) stretches along the first front side (234); and a invention allows for other connection arrangements. The adaptor member (229) is along the second front side (239) provided with two lower (245) lock plates and two upper (246) lock plates, fixedly attached to the second support plate member (233), positioned such that they fit the lock chambers (247) of the sliding block parts (248)(249), such that the sliding block parts (248)(249) can be centrifugally locked to the attachment member (232) of prior art, with the aid of the adaptor member (229), essentially in a way similar to the seventh configuration of a composed accelerating member (182), from figure 26.

Figure 33, shows, diagrammatically, a 3D view of a fourth configuration of a rotor

(267), for one-way operation (251), according the invention, provided with a an eighth configuration of a composed accelerating member (250), according the invention; comprising an attachment member (252) and a sliding block member (253); each of two parts; an outer sliding block member (254), detailed in figure 34, provided, along the outer back side (255), with an outer lock member (256), provided with an outer cylindrical pivot opening (257); and an inner sliding block member (268), detailed in figure 35, provided, along the inner back side (259), with an inner lock member (260), provided with an inner cylindrical pivot opening (261), the pivot openings (257)(261) stretching throughout the lock members (256)(260) in a vertical direction; an outer attachment member (262), presenting an outer pivot cylinder (263), and an inner attachment member (264), presenting an inner pivot cylinder (265), the pivot cylinders (263)(264), stretching upward from the top side (266) of the rotor (267), in a vertical direction, such that the inner pivot cylinder (265) fits the inner pivot opening (261), and the outer pivot cylinder (263) fits the outer pivot opening (257), firmly attaching the sliding block members (254)(268) separately to the attachment member (252). The outer sliding block member (254) is, here, along the outer inner block side (269) provided with a stub member (270) that fits a stub opening (271) stretching along the inner outer block side (272), such that a separation joint (273) is created with a radial section (274) that provides a pressure face (275), creating an interaction between the sliding block parts (254)(268), for transfer of force (276) from the inner sliding block part (268) to the outer sliding block part (254).

The eighth configuration of a composed accelerating member (250), has the ^~ advantage that both the sliding block parts (254)(268), the attachment members (262)(264), and the rotor (not shown here), are very simple, effective, and very easy for exchange, and the pivot cylinders (263)(265) are fully protected, essentially also when the sliding block parts (254)(268) wear through, presenting a semi-permanent rotor construction.

Figure 42 and 43, shows, diagrammatically, a fourth configuration of a rotor (330) according the invention, for two-way operation (331), provided with a ninth configuration of a composed accelerating member (332), according the invention, symmetrical to the radial plane (360) from the axis of rotation (0), based on figure 37, to which reference is made. The radially arranged multiple block sliding member (333), is of two sliding block parts (334)(335); the configuration based on, but not identical to, the known rotor from WO 2010/008273, which is name of applicant, to which reference is made. The inner sliding block part (334), detailed in figures 44, is provided with an inner outside block side (336), and the outer sliding block part (335), detailed in figures 45, is provided with an outer inside block side (337), the inner sliding block part (334) providing two inner sliding face parts (338)(339), one for each direction of rotation (340), the outer sliding block part (335) providing two outer sliding face parts (341)(342), one for each direction of rotation of rotation (340), such that two radially arranged multiple sliding faces (343)(344) are created, for each direction of rotation (340).

The inner sliding block part (334) is pivotally attached to the rotor (330), with the aid of an inner attachment arrangement (345) that comprises a first pivot member (346) carried by the inner sliding block part (334), and a second pivot member (347) carried by the rotor (330). The first pivot member (346) stretches underneath the inner sliding block part (334) along the inner bottom side (348) and presents a first sleeve member (349), with a first open side (350) into the direction of the rotor (330) and a second open side (351) into the direction of the outer edge (352) of the rotor (330), and a half conical cylindrical face (359) along the standing closed side, opposite of the first open side (350), creating a first angled conical pressure face (359) widening (353) upwards (354) into the direction of the inner bottom side (348), directed away from the axis of rotation (0). The second pivot member (347) present a conical pivot cylinder (355) that protrudes vertically from the rotor (330), widening (356) in upwards direction (354), the pivot axis (00) parallel to the axis of rotation (0), which second pivot member (347) is provided with a second angled pivotal pressure face (677), widening (353) in upward direction (354), such that the first pivot member (346) fits the second pivot member (347) creating a pivotal contact face (678) stretching between the first (359) and the second (677) pivotal pressure face, angled upwards (354) into the direction toward the axis of rotation (0). Furthermore, the point of gravity (357) of the inner sliding block part (334) is positioned at a larger radial distance (358) form the axis of rotation (0) than the pivot axis (00), such that the inner attachment arrangement (345) provides centrifugally locking of the inner sliding block part (334) to the rotor (330), pivotally, when positioned in radial position (360), the widening (353) conical shape of the pivot cylinder (355), hindering movement radially outward (362) and in axial (363) direction.

Not shown here, in an essentially similar way, it is also possible to provide the sliding block part along the bottom side with a conical pivot member stretching downward, widening, for the bottom side, presenting a first angled pivotal pressure side, and provide the rotor with a pivot opening, provided along the side facing the axis of rotation, with a angled second pivotal pressure side, fitting the first pivotal pressure side, creating an angled pivotal contact face, widening in upward direction, hindering movement radially outward and in axial direction.

The outer sliding block part (335) is, here, fixedly attached to the rotor (330), with the aid of an outer attachment arrangement (364) that comprises a first hook member (365), carried by the outer sliding block part (335), and a second hook member (366) carried by the rotor (330). The first hook member (365) stretching underneath the outer sliding block member (335), fixedly attached, along the outer bottom side (367) and presents, here, a second sleeve member (368), open (369) into the direction of the rotor (330) and open (370) into the direction of the outer edge (370) of the rotor (330), and along the closed side (370) provided with the first hook member (365), open (372) into the direction of the outer edge (373) of the rotor (330). The second hook member (366) present, here, a hook plate member (374) stretching into the direction of the axis of rotation (0), such that the second hook member (336) fits the first hook chamber (365), such that the outer attachment arrangement (364) provides centrifugally locking of the outer sliding block part (335) to the rotor (330), fixedly, hindering movement of in radially outward direction (362) and in axial direction (0).

The first sleeve member construction (349) protects the second pivot member (347) and the second sleeve member construction (368) protect the second hook member (366), such that they are not exposed to stray and rebounding particle material.

The inner outside block side (336) and the outer inside block side (337) stretch here around the circle (375) of the pivot axis (0), fitting each other along an open separation joint (376), such that the inner outside block side (336) can pivot along the outer inside block side (337). As is indicated in figures 41, the second hook member (366) is along the standing inside (377) facing the axis of rotation (0) at a location underneath the outer sliding block part (335), provided with a horizontal pressure plate (389), fixedly attached, stretching into the direction of the axis of rotation (0), such that the outer edge (390) of the inner bottom side (348) rests onto the pressure plate (389). As indicated in figure 47, the rotating inner sliding block part (334) turns (390) under influence of inner centrifugal force (391), with the outer sliding block part (335) turning (392) under influence of the outer centrifugal force (393), the inner turning (390) creating an inner downward turning force (407) onto the pressure plate (389), and the outer turning (392) creates an outer upwards turning force (408), opposite to the inner downward turning force (394), creating an interaction via the pressure plate (389) between the inner slicing block part (334) and the outer sliding block part (335), which significantly reduces the net force (394) acting on the outer attachment arrangement (364), creating a significant stress reduction in the first hook member (365) and the second hook member (366), allowing for a lighter construction of the second attachment arrangement (364).

As indicated in figure 42 and 43, the outer sliding block part (335) is positioned first, by sliding it radially outwards (395), such that the second hook member (366) fits the first hook member (365), for centrifugal locking. Next, the inner sliding block part (334) is positioned, by sliding it transversally (396) with the first open sleeve member (394) over the second pivot member (347), such, that it fits the first pivot member (346), when the inner sliding block part (334) is turned (397) in its radial position (360), for centrifugally locking, with the inner outside block side (336) stretching along the outer inside block side (337), leaving an open separation joint (376), and with the outer edge (398) of the inner bottom side (348) onto the pressure plate (389). Centrifugal locking of the inner sliding block part (334) is here obtained, with the aid of the conical pivot cylinder (355) that hinders movement radially outward (391) and axial upward (354), and outer edge (371) of the centre rotor part (564) hinders the inner standing edge (371) of the inner sliding block part (334) to move inward toward the axis of rotation (0), providing the inner sliding block part centrifugal locking, such that pivotal movement is not hindered.

The inner sliding block part (334) is provided with a first stoppage plate member (398), stretching, here, vertically along one radial side (399) of the inner bottom side (348), and the outer sliding block part (335) with a second stoppage plate member (400), here provided by the vertical side of the pressure plate (389), such that the first stoppage plate (398) stretches along the second stoppage plate (400) when the inner sliding block part (334) is turned (397) into its radial position (360) during instalment, hindering further turning movement (397) into that direction, and hindering turning movement (397) when the stopped inner sliding face (404) starts to wear out (403); which means that positioning of the inner sliding block part (334) is only possible in one turning direction (397), and that operation of the rotor (330) must start into one direction of rotation (409), that is with material fed to the stopped inner sliding face (404). The opposite inner sliding face part (405) will than stay in line with the outer sliding face part (342), and can be used when the stopped inner sliding face (404) is worn out (403) and direction of rotation (340) is reversed.

The fourth configuration of the symmetrical rotor (330) has the advantage that the rotor (330) construction is extremely simple, comprising a rotor blade (406) with connection inner (410) and outer (407) openings, and that the second pivot members (346) and second hook members (366) are not exposed, completely protected by the first (349) and second (368) sleeve members. The outer attachment arrangement (364) provides very easy exchange, and does not require a separate support element, as is the case with the known pivot rotor cited before. The conical pivot cylinder (355) provides very easy inner attachment arrangement (345), and prevents breakage of the lip construction, that is attached to the known rotor. Otherwise, the fourth configuration (330) provides the same features as the known rotor, that is, very easy exchange, strongly reduced lifting weight, for example, between 15 -25 kg, without effecting sliding/acceleration performance, provides two way operation (331) until one of the sliding block parts (334)(335), burns through and breaks away, without causing damage to the rotor construction (330), providing a permanent rotor (330), which enables maximum utilization of the construction material.

The tenth configuration (417) resembles the ninth configuration (332), to which reference is made, but provided with a different attachment arrangement (420), for fixedly attachment of the sliding block parts (418)(419) along the bottom sides (421)(422) with the aid of attachment members, here lock openings (429)(430) in the top side (361) rotor (415)

The inner sliding block part (418), detailed in figure 50, and the outer sliding block part (419), detailed in figure 51, are each, along the bottom side (421)(422), provided with an, essentially similar, stub member (423)(424) that is provided with a first vertically pressure face (425) directed away from the axis of rotation (0), and a lip member (427)(428) stretching into the direction of the axis of rotation (0) provided with a first horizontal pressure face (426). As indicated in figures 49, the rotor (415) is provided with inner lock openings (429) and outer lock openings (430), that fit the inner (423) and outer (424) stub members, such that, as indicated in figures 52 and 53, the stub members (423)(424) can be easily inserted, and slid outward, such that the first pressure face (425) is pressed against the second vertical pressure face (431) of the lock openings (429)(430), with the first horizontal pressure face (425) positioned partly underneath the second horizontal pressure face (432) provided by the lock openings (429)(430), hindering radial outward movement (433) of the rotating sliding block parts (418)(419). The second vertical pressure side (431) and first vertical pressure faces (425) are, here, stretching, slightly angled, upward, into the direction (441) of the axis of rotation (0), hindering upward, axial (0), movement (434) of the rotating sliding block parts (418)(419); centrifugally locking the sliding block parts (418)(419) to the rotor (415). The attachment arrangement (420) is located at a position below the horizontal plane (412) with on it the outer edge (413) of the feed area (414), avoiding damage to the attachment arrangement (420) during operation of the rotor (415), providing a permanent rotor (415);

The fifth configuration of the symmetrical rotor (415) is arguably even simpler than the fourth configuration (330), presents essentially similar advantages, that is, that the rotor (330) is extremely simple, comprising a rotor blade (415) with lock openings (429)(430), the attachment arrangement (420) is not exposed, and provide very easy exchange, the lifting weight is significantly reduced, for example 15-25 kg, without effecting sliding/acceleration performance, provides two way operation (416), until one of the sliding block parts (418)(419), breaks away, without causing damage to the rotor (415) construction, providing a permanent rotor (415), which enables maximum utilization of the construction material.

Figures 54, shows, diagrammatically, a 3D view of an eleventh configuration of the radially arranged multiple block sliding member (435), according the invention, based on the sliding block member of figure 48, provided with hard metal part, here, hard metal chips (440), for example of tungsten carbide, that is, along the sliding faces (437)(438), creating hard metal sliding faces (411), along the inside inner block side (436), and partly along the outside outer block side (439), which makes it possible to significantly extend life time of the sliding block parts (418)(419) in service; which chip members (440) can, according the invention, also be applied with other configurations of the sliding block parts. The invention allows for other configurations of the hard metal parts (440). Tungsten carbide is very heavy which makes the radially arranged multiple block sliding member (435), according the invention, eminently suitable for application of such hard metal sliding faces (411), presenting the possibility to construct this eleventh configuration of the sliding block member (435) of three, or more, radially arranged sliding block parts (not shown here), to reduce handling weight and the forces acting on the attachment arrangement (420) to practical levels.

Figure 55, shows, diagrammatically, a sixth configuration of a rotor (445) according the invention, for two-way operation (446), provided with a eleventh configuration of a composed accelerating member (447), according the invention, based on figure 39, with the radially arranged multiple block sliding member (447), of three sliding block parts (448)(449)(450), two outer sliding block parts (449)(450), detailed in figures 58, each provided with an outer inside block side (451)(452), and one inner sliding block part (448), detailed in figures 59, provided with two inner outside block sides (453)(454), each outer sliding block part (449)(450) providing an outer sliding face part (455)(456), for each direction of rotation (446), the inner sliding block part (448) provided with two inner sliding face parts (457)(458), one for each direction of rotation of rotation (446), such that two radially arranged multiple sliding faces (459)(460) are created, each of two sliding face parts, (455)(456)(457)(458), for each direction of rotation (446), and is a preferred configuration for two-way operation (446) of the rotor (445).

The outer sliding block parts (449)(450) are symmetrical to the horizontal plane (499), applicable right and left of the symmetrical radial plane (462) from the axis of rotation (0), that is, suited for each direction of rotation (446); each, provided, here, along the outer side (467) of the outer back block side (471), with a cylindrical stub member (466) protruding from the outer back block side (471), angled, into the direction of the axis of rotation (0), and, along the inner side (468) with a strip member (469), that extends into the direction of the axis of rotation (0), beyond the outer inner block side (451) creating a protruding attachment lip member (470), with the top side (494) and the bottom side (495) of the lip member (470) stretching, symmetrical to the horizontal plane (499), respectively angled upward and angled downward into the direction of the axis of rotation (0), creating angled lip lock sides (496)(497); the outside inner block side (451) stretching angled downwards, away from the axis of rotation (0).

The rotor (445) is provided with attachment block members (461), detailed in figure 57, each, symmetrical to the radial plane (462) from the axis of rotation (0), and, here, along the bottom side (442) provided with a hook member (443), for easy separate exchange, in case of damage, and presents two standing radial support sides (463)(464) stretching into the direction of the outer edge (465) of the rotor (445), each, provided with a cylindrical stub opening (474) that fits the cylindrical hook member (466) and along the centre of the inner support side (473) with a sleeve opening (472), that fits the strip member (469), such that the lip member (470) protrudes beyond the inner support side (473) of the attachment block member (461),

The inner sliding block part (448), positioned on the top side of the rotor (445) is not fixedly attached to the attachment member (461), but pressed against an outer inner block side (452), under influence of centrifugal force, along the back block side (provided with a lock space (476), positioned between the two inner outside block sides (453)(454), open into the direction of the axis of rotation (0), closed along the top side (477) with a lock edge (485), stretching angled upward, away from the axis of rotation (0), the back side (480) closed, stretching vertically downward, between two side edges (478)(479), the inner outside block sides (453)(454), stretching angled downwards, away from the axis of rotation, fitting the outer inside block sides (451)(452).

For instalment, the outer sliding block parts (449)(450) are positioned (567) along the respective radial support sides (463)(464) of the attachment block member (461), such that the cylindrical stub member (466) fits the stub opening (471), and the strip member (469) fits the sleeve opening (472); the lip members (470) protruding from the outer inside block sides (451)(452) and the inner support side (473); next, the inner sliding block part (448) is positioned, sliding vertically downwards (483), with the angled inner outside block sides (453)(454) stretching along the angled outer inside block sides (451)(452), and the standing side edges (478)(479) stretching along the strip members (469). The cylindrical stub opening (474) and the standing side edges (478)(479) hinder the outer sliding block member (449)(450) to move away from the radial support sides (463)(464), the sleeve opening (472) hinders the outer sliding block parts (449)(450) to move upward in axial direction, and inner sliding block part (448) is hindered to move upwards by the angled outer inside block sides (451)(452), along the top side hindered to move away from the outer inside block sides (451)(452) by the angled lip lock sides (496)(497); and the inner block side (498) of the inner sliding block part (448) is along the bottom side (487) provided with an inner bottom sleeve (488) that fits then outer edge (489) of the feed plate (490), further hindering the inner sliding block part (448) to move into the direction of the axis of rotation (0).

Which means that the sliding block parts (448)(449)(450) are centrifugally locked to the rotor (445), hindering movement in a direction radially outward and in axial direction upward.

The attachment member block (461) is along both radial support sides (463)(464), and along the inner support side (473) protected by the sliding block members (448)(449)(450); the outer side (492) of the attachment block member (461), here, protected for rebounding material with the aid of an exchangeable outer protection plate (493).

Figures 60, shows, diagrammatically, a 3D view of a seventh configuration of a rotor (540) according the invention, for two-way operation (541), provided with a twelfth configuration of a composed accelerating member (542), according the invention, of three sliding block parts essentially similar the tenth configuration of figures 50 and 51; wherein, as indicated in figure 61, the two outer sliding block parts (544)(545) are positioned adjacent to each other, butted up along the outer back block sides (546)(547).

The outer sliding block part (544), detailed in figure 62, is along the bottom side provided with a outer stub member (550), described before with figure 50, to which reference is made, provided with an outer angled vertical pressure face (551), stretching upward in the direction of the axis of rotation (0) and an outer lip member (552), fitting the vertical and horizontal pressure sides (not shown here), of the lock opening (548) in the rotor (540); the adjacent outer sliding block parts (545)(546) and the associated outer lock openings (548)(549) are symmetric along the radial line (555) with on it the outer back block sides (546)(547), the outer back block side (545) positioned opposite of the outer sliding block side (562).

The inner sliding block part (543), detailed in figure 63, is, here, in a similar way provided with an inner stub member (556), fitting the inner lock opening (557), such that the two inner outside block sides (558)(559) fit the outer inner block sides (560)(561), here, such that the inner outside block sides (558)(559) do not press against the outer inside block sides (560)(561), avoiding extra stress in the outer stub members (550); but the invention allows for the inner sliding block part (543) to be centrifugally locked with the aid of the outer sliding block parts (544)(555), when the centrifugal force generated by the inner sliding block part (543) is transferred to the outer sliding block parts (544)(555), in a way similar to the eleventh configuration (447) of figure 55.

The seventh configuration (540) provides attachment inside the lower blade, such that the inner attachment arrangement and the outer attachment arrangements do not become damaged when the sliding block parts (543)(544)(545) burn through and break away, presenting a permanent rotor that allows for optimal utilization of the sliding block construction material, but requires a stub members (550)(556), which are avoided with, for example, the seventh configuration (447) of figure 55; wherein, however, the attachment block member (461) becomes damaged when the sliding block parts (448)(449)(450), but can be easily exchanged. Furthermore, exchange of the sliding block parts (543)(544)(545) is very easy.

Figure 64, shows, diagrammatically, a 3D view of a eighth configuration of a rotor (500) according the invention, for two-way operation (501), provided with a thirteenth configuration of a composed accelerating member (502), according the invention, of three sliding block parts (503)(504)(505), also based on figure 39; essentially similar to the sixth configuration (445), provided with a different attachment arrangement (506); the radially arranged multiple block sliding member (507), of, two outer sliding block parts (504)(505), each provided with an outer inside block side (508)(509), and one inner sliding block parts (503), provided with two inner outside block sides (510)(511), each outer sliding block part (504)(505) providing an outer sliding face part (512)(513), for each direction of rotation (501), and an inner sliding block part (503) provided with two inner sliding face parts (514)(515), one for each direction of rotation of rotation (501), such that two radially arranged multiple sliding faces (516)(517) are created, for each direction of rotation (501).

The attachment block member (518), is symmetrical to radial plane (519) from the axis of rotation (0), for attachment of the outer sliding block parts (504)(505), each with the aid of an outer attachment arrangement (506), similar to the attachment arrangement (196) from the second configuration of the rotor (180), form figure 26, discussed before.

Each outer sliding block part (504)(505), is provided with two open centrifugal locking chambers (509), a lower locking chamber stretching along the outer bottom block side (not shown here), and an upper locking chamber (509), stretching along the top block side (524), each provided with a standing pressure side directed away from the axis of rotation (0). The attachment block member (518) is along each radial support side (521) provided with two centrifugal locking plates (522), stretching from the radial support side (513) into the direction of rotation (501), such that the locking plates (515) fit the locking chambers (509), centrifugally locking the outer sliding block parts (504)(505) to the attachment block member (518), avoiding the need for any separate locking and securing arrangement. The outer attachment block side (566) is here protected with hard metal parts (567).

The inner sliding block part (503), essentially similar to the inner sliding block part (448) from figure 59, discussed before, positioned after the outer sliding block parts (504)(505) have been attached, with the inner outside block sides (510)( 11) stretching along the outer inside block sides (508), hindering sideward movement of the inner sliding block part (503), and the inner middle part (not shown here) of the inner outside block side (503), stretches along the inner support side (523), which stretches angled downwards away from the axis of rotation (0), hindering movement of the inner sliding block part (503) in upward direction, such that all three sliding block parts (503)(504)(505) are separately centrifugally locked to the rotating attachment block member (518).

The twelfth configuration (502) has the advantage that the outer attachment arrangement (506) does not require a stub member, likewise the twelfth (542) and the thirteenth (502) configurations, which saves significantly on construction material and makes the attachment block member (518) easier to construct, and the locking chambers (508)(509) present a further saving on construction material, without affecting performance. Figure 65, shows, diagrammatically, a 3D view of a ninth configuration of a rotor (525) according the invention, for two-way operation (526), provided with a fourteenth configuration of a composed accelerating member (527), according the invention, of four sliding block parts (528)(529)(530)(531), based on figure 41, to which reference is made; the radially arranged multiple block sliding member (524), of two outer sliding block parts (528)(529), essentially similar to the thirteenth configuration (502), to which reference is made, each provided with an outer inside block side (532), and two inner sliding block parts (530)(531), split along the radial plane (5240 from the axis of rotation (0), each provided with an inner outside block sides (533), each outer sliding block part (528)(529) providing an outer sliding face part (534), for each direction of rotation (526), each inner sliding block part (530)(531) provided with a inner sliding face part (535), one for each direction of rotation (526).

The attachment block member (537), provide, along each radial support side (538), with two sets of upper and lower locking plates (539)(540) that fit the locking chambers (not shown here) of the sliding block parts (528)(529)(530)(531), for attachment of two sliding block parts (528)(530)/(529)(531) along each radial support side (538), creating a radially arranged multiple block sliding member (528) of four parts (528)(529)(530)(531), with two radially aligned multiple sliding faces (536), for each direction of rotation (526).

The eighth configuration of the rotor (525) can be very strongly constructed, for example, for attachment of four sets of four 30 kg (and more), sliding block parts (528)(530)/(529)(531) resulting in four radially arranged multiple block sliding parts (527) of 120 kg each, or instalment of some 480kg (and more) of wear construction material on top (543) of the rotor (525), increasing rotor service time accordingly; and the 30kg sliding block parts (528)(530)/(529)(531) are with the lock chamber/lock plate attachment arrangement (536) easy for exchange.

The accelerating member according the invention is eminently suited when very heavy construction materials are applied, in particular hard metal, like tungsten carbide, that presents very high wear resistance, and sliding block parts and the invention allows for the sliding block parts to be provided with a sliding face at least partly constructed of hard metal parts, extending lifetime in significant way. According the invention, next to the sliding face also other parts of the working face, exposed to contact with particle material, can be provided with had metal parts, or ceramic parts, to increase wear resistance; But hard metal is also very heavy, tungsten carbide in particular, substantially increasing handling weight and stresses in the attachment arrangement. The accelerating according the invention makes it possible to construct hard metal sliding block parts, that limit the handling weight, and limit stresses in the attachment arrangement, as has been shown with the composed accelerating member with the second configuration (90) from figure 9, the fourth configuration of figure 15, and the tenth configuration of figure 54, and can be applied with the other configuration according the invention. Moreover, firm attachment of the hard metal parts often requires a steel base construction, which has the advantage over casted parts, that it steel is very strong, can be obtained at various strengths, that steel is homogenous, and does not contain possible irregularities within the structure, which cannot be avoided with casted materials and may cause breakage, steel allows for very accurate configurations, which cannot be attained with casted materials, and steel is cheaper than casted materials, and can therefore be applied to construct more efficient accelerating members according the invention; that is, with more simple and very strong configuration, and simple and very strong attachment arrangements, that may further reduce construction weight, or at least compensate heavy weight hard metal.

Figure 66, shoes, diagrammatically, a tenth configuration of a rotor (570) according the invention, for two-way operation (571), provided with a fifteenth configuration of a composed accelerating member (572), according the invention, of two sliding block parts (574)(575), detailed in figures 67 and 68, providing hard metal sliding face parts (573)(569), essentially similar to the eleventh configuration (435) of figure 54, and allows for three or more radially aligned sliding block parts (not shown here) to further save on weight. Each sliding block part (574)(575) comprises a base block member (576), here, of steel, providing a support side (578) to firmly connect hard metal chip members (577), comprising, for example, a hard metal plate member (578) firmly attached to a steel carry member (579), detailed in figure 69, crating hard metal sliding faces (580)(581); as indicated, the invention allows for other configurations of the hard metal parts.

The base block member (576) is along the bottom base block side (582) provided with a cylindrical lock opening (583), stretching upwards in a vertical direction, fitting cylindrical bar members (584) protruding upwards from the top side (585) of the rotor (570) in a vertical direction, fitting the cylindrical lock opening (583), providing a very simple cylindrical attachment arrangement (586), for very easy exchange, sliding the cylindrical lock opening (583) over the cylindrical bar member (584), and is very easy to construct and the cylindrical attachment arrangements (586) adds no weight to the accelerating member (572), and the cylindrical bar member (584) provides regular stress distribution. The cylinder axis (00) stretches along the radial plane (587) from the axis of rotation (0), slightly angled inwards (568) in upward direction, some 2-3 degrees, with the top side (588) of the cylindrical bar member (584) stretching at a level above the horizontal plane (589) that stretches along the point of gravity (590) of the sliding block part (574)(575), hindering upward movement of the sliding block part (574)(575). It is preferred that the cylinder axis (00) is positioned at a closer radial distance from the axis of rotation (0) than the point of gravity (590). Cylindrical bars have the advantage of even stress distribution, but the invention allows also the cylinder to present a polygon, preferably regular convex, or a plate member inserted in the rotor (all not shown here).

As indicated in figures 67 and 68, the inner inside block side (592) and the outer outside block side (597), fitting each other, are, here, each of two angled planes (593)(594), but can also be curved or otherwise interlocked, creating a separation joint (595) that not stretches along a straight plane, such that pivoting movement of the rotating sliding block members (574)(575) is hindered.

The cylindrical lock opening (583) is along the top side (588) closed, hindering ingress of fine particle material, and protects the cylindrical bar member (584), but can in case of damage be easily exchanged. The rotor (570) is of very simple construction, only providing the cylindrical connection openings (596) to connect the cylindrical bar members (584), firmly but exchangeable, to the rotor (570).

Figure 70, shows, diagrammatically, an eleventh configuration of a rotor (600) according the invention, for either one-way (622) operation or two-way operation (601), provided with a sixteenth configuration of a composed accelerating member (602), according the invention, of two sliding block parts (603)(604), detailed in figures 72 and 73, provided with hard metal sliding face parts (605), provided with an attachment arrangement (606) essentially similar to fifth configuration of the rotor (415) of figure 52, to which reference is made, and allows for three or more radially aligned sliding block parts (not shown here), to further save on weight.

The hard metal sliding face parts (605) are firmly connected to the base block part (607) along the support sides (608)(609). The base block part (607), detailed in figure 71, presents, here, a rectangular block member (613) of steel, stretching parallel between the support sides (608)(609), symmetrical to the straight plane (611), possibly the radial plane (612) from the axis of rotation (0), and the rectangular block member (613) is along the lower edge (614) provided with an attachment part (615), essentially similar to the stub member (423) from the fifth configuration (415) of figure 50, provided with a first vertical pressure face (616), directed away from the axis of rotation (0), stretching vertically, slightly angled downward towards the axis of rotation (0), and a lip member (617) stretching into the direction of the axis of rotation (0), provided with a first horizontal pressure face (618), facing upward - such that the base block part (607) can be cut from a steel plate. At least one support side (608) is, here, provided with hard metal sliding face parts (605), here, hard metal chips (619), here, similar to the chip (577) from figure 69, fixedly attached to the support side (608), creating a sliding block parts (647), provided with hard metal chips (619) along one support side (629) of the base block part (607), for one-way operation (622) of the rotor (600), or with hard metal chips (619) along two support sides (630)(631) of the sliding block parts (603)(604), for two-way operation (601) of the rotor (600), indicated in figures 70.

The sliding block parts (603)(604) can stretch along the radial plane (612) from the axis of rotation (0); but with one-way operation (602), the sliding face (628) can be turned (648) in a forward position, into the direction of rotation (602), to slow down the velocity of the particles along the sliding face (628), reducing the wear rate.

As indicated in figures 74 and 75, for attachment, the sliding block part (603)(604) is positioned an attachment opening (624) in the top side (625) of rotor (600), preferably through the rotor (600), avoiding accumulation of fine particle material, provided with a second vertical pressure side (626) directed toward the axis of rotation (0), stretching vertically, slightly angled downward away from the axis of rotation (0), fitting the first vertical pressure face (616), and a second horizontal pressure side (632), facing upward, fitting the first horizontal pressure face (618) - such that the attachment part (615) fits the attachment opening (624), creating an attachment arrangement (606), where the sliding block part (603)(604) is slid into the attachment opening (624), slid outwards, the first vertical pressure face (616) butted up against the second vertical pressure side (626), as indicated in figure 75, centrifugally locking the sliding face part (603)(604) to the rotor (600), hindering movement radial away from the axis of rotation (0) and upwards in axial direction (0). In this respect it is important that the attachment arrangement (606), with both attachment part (615) and attachment opening (633) constructed of steel, can be very accurately manufactured, providing perfect locking along the pressure sides (616)(618)(626)(632). As indicated in figure 75, positioned for operation, a sliding opening (633)(634) is created, the outer sliding opening (634) covered by the bottom side (635) of the inner sliding block part (603), the inner sliding opening (633) not covered. This means that the inner sliding opening (633), and possibly also the outer slide opening (634), may fill with fine particle material during operation, that may hinder unlocking of the sliding block parts (603)(604) for exchange, which can be prevented by placing a fill block (636) in the sliding opening (633), that can be constructed of plastic or another material.

The invention allows for the radially aligned sliding faces to stretch forward (645), that is, into the direction rotation (646); and the invention allows for other configuration; for example, the radially aligned multiple sliding face not stretching along a straight plane (not shown here).

The invention allows for the base block member (637) to be, of two parts (638)(639), symmetrical split, here, along a straight plane (610), creating two base block back sides (640)(641), facing each other, such that the hard metal chips (619) can be attached via the base block back sides (640)(641), for example bolted.

Another arrangement of the base member (623) with two split parts (627)(628), creating two separate radially aligned sliding multiple sliding blocks (651)(652), each of two sliding block parts (653)(654), positioned symmetrical to the radial plane (655) from the axis of rotation (0), the back sides (656)(657) facing each, providing two radially aligned sliding faces (658)(659), one for each direction of rotation (601), the radially aligned sliding faces (651)(652) stretching along the radial plane (644) from the axis or rotation (0).

Figure 76, shows a simple arrangement (649) of the eleventh configuration of the rotor (600) provided with five sets (650) of these separate radially aligned sliding multiple sliding blocks (651)(652), providing ten radially aligned multiple sliding faces (658)(659), which arrangement (649) provides very long lifetime, and wide uninterrupted space (661) between the sliding faces (658)(659), for processing large amounts of coarser material at high capacity, between exchange of the sliding block parts (653)(654). As indicated figure 76, the radially arranged multiple block sliding member (665) can be of three parts, an inner sliding block part (662), a centre sliding block part (663) and an outer sliding block part (664), to save further on weight, providing a radially aligned multiple sliding face of three sliding face parts (666), for each direction of rotation (601). The eleventh configuration of the rotor (600) is very simple only providing the connection openings (647) for the attachment parts (615), and is permanent, because the attachment openings (647) cannot become damaged; and also the sliding block parts (603)(604) are very simple, cheap to construct, with easy attachment of the hard metal parts, providing also very easy exchange, and can be configured for one-way (622) and two-way operation (623); and the rotor (600) and the accelerating members (602) presents a preferred configuration, according the invention, when hard metal radially aligned multiple sliding faces (658)(659) are applied.

Figure 77 - 79, show, a possible dovetail connection arrangement (672) for the hard metal chips (619) to a metal base block part (607)(666), according the invention, wherein the hard metal chip (619)(667), detailed in figure 77, is along the back side (668) provided with a dovetail member (669), that fits the dovetail sleeve opening (670) in the front side

(671) of the base block part (666); which presents a very easy connection arrangement

(672) . The invention allows for the hard metal chips (619) to be otherwise connected to the metal base block part (607), for example bolted or soldered. Furthermore, the invention allows, for the base block part (607)(666) to be provided with hard metal sliding face parts (605)(619)(667) along both the front side (671) and the back side (673), creating a sliding block part (674) provided with two hard metal sliding face parts (675)(676), for each direction of rotation (601), that is, for two way operation (601) of the rotor (600), which attains extremely long lifetime.

Hard metal parts, for example rods and chips, my be connected to the sliding block part involving heat treatment, which may cause residual stresses in the construction behind the metal parts, when it may be preferred to connect the metal parts to a separate part or section to be firmly connected to the sliding block part. Figure 80-82, show, diagrammatically, a sliding block part (680), according the invention, essentially similar to the sliding block part (604) of figure 72, here, of three separate section parts (681)(682)(683), a base section part (681), a sliding section part (681) and an inner section part (683), the section parts (682)(683) fixedly connected to the base section part (681). The connected section parts (682)(683) are each provided with a hard metal protection layer (686)(687), creating, here, a hard metal sliding face (689) and a hard metal inside inner block side (690), and are, here, along the opposite section sides (691)(692) provided with a stub member (693)(694), that fits the insert openings (691)(696) in the base section (681); the connected section parts (682)(683) are, here, connected with the aid of bolt members (not shown here) that fit the bolt openings (684)(685) in the connected section parts (682)(683) and in the base section part (681); creating a sliding block part (680) provided with a wear protection layer (686)(687) along part of the working face (688), exposed to contact with particle material; and the outer outside block side (695) can also be provided with such partly inserted section part (not shown here). Not shown here, the connected section parts (682)(683) can, according the invention comprise two or more section parts, for example to provide the sliding block part (604) with two connected section parts each providing a sliding face part, for each direction of rotation. The technique of connected section parts (682)(683), can, according the invention also be connected with other connection arrangements, and also be applied with the other configurations of the sliding block parts, here shown, and sliding block parts possible according the invention.
