Technical Field

The invention relates to the chromium separation table, with the ability to manually or automatically move on the multi - axis, which recovers the mine leak within the waste in chromium separation plants.

Prior Art

Since limited intervention can be made in the mine separation tables used in the current technique, equal and stable adjustment cannot be made due to the variable mineral flow process. The table that is not accurately adjusted results in high rates of loss and leakage. For example, the four separate feet of the table cannot be adjusted equally on the field and therefore an equal load cannot be placed on the feet. This causes the table to shake towards the foot that takes less load and the material to mix. It causes the mixed material to leak or that the table cannot fully purify and separate. Therefore, the concentrate, which cannot be fully purified, is sold at a lower price.

In the current technique, all adjustments made to the table can not be measured as front tilt, side tilt, frequency adjustment and spring print settings numerically. The adjustments are made via user experience, initiative or eyeball estimation. This situation causes losses and leakages as a result of tens or hundreds of tables working in different settings in production depending on the size of the enterprise.

However, since the table and transmission box are mounted independently, the disruption of the most important parameters in the slope settings, which are the transmission stroke axis and the axis of the table slats, is experience. This causes the table to stir up the mine, the mineral to go into waste or the obtaining of a concentrate that cannot be fully purified.

On the other hand, to ensure the forward and backward movement of the table, the roller bearing motion system or mechanical skid system is used under the table. These two methods put too much load on the transmission box and accordingly cause malfunction. Transmission box and skid system parts require continuous maintenance, lubrication, spare parts and posture.

However, due to mechanical equipment, the tables are unable to reach the high speeds and frequencies required for fine grains. Most of the fine grains go to waste (tallow) as a result of these.

In the patent survey conducted regarding the prior art, the application number TR2017 / 03014 was found. The abstract of the application states as follows: It is an enrichment facility that comprises of mines, cyclones, pumps, separators, transfer elements, separating elements, which allows the mines to be enriched on - site without the need to move the mines, and its feature includes the main chassis that allows the enrichment facility to be transported by hosting all the elements together.

The Purposes of Invention

The invention is related to a chromium separation table with different technical features which, unlike the structures used in the present technique, brings a new development to this area.

The most fundamental purpose of the invention is to recycle and recover mine leaks within previous production wastes. It is also to reduce the leakage rate by the use of it in the production plants that are still in use.

Another purpose of the invention is to enable the chromium separation table to be adjusted to the desired extent manually or automatically via its two separate tilt control arms without requiring any equipment.

Another purpose of the invention is to observe and record the settings made by means of the settings display screen. In addition, the slope settings made can be measured analog and digitally.

Another purpose of the invention is to configure the transmission box and the table on the same frame. Thus, there is no deterioration experienced in the axis of the slab and lath since it is mounted on a single frame.

Another purpose of the invention is to suspend the table that performs the elimination process in a way to make a four - point swinging motion. With this swing motion supported by steel ropes, the system will provide a comfortable and stable swinging movement.

Another purpose of the invention is that it has a feature that allows for high speed and frequency adjustment.

Another purpose of the invention is that the geometric slab design of the table and the lath design on it are designed for the harmony of completely new working mechanisms.

The purpose of the invention is to make the table tilt settings mechanically, PLC or digital control with the motor speed drive.

The purpose of the invention is to give an extra 3 % slope to the section at least 50 cm wide, which is located at the end of the mineral washing area of the table.

With the mineral separation tables used in the prior art, there are millions of tons of waste (tallow mountains) processed in front of chromium concentrate mining facilities in our country and world. It is aimed to recover approximately 3 % to 8 % of the leakage found in this waste (tallow) which is leaked by existing separation table technology by 70 % to 80 %.

If it is considered that the rate of tenor in the mine, which many mining companies in our country have just extracted from nature, is 5 % to 15 % on average, and the loss and leakage between 3 % and 8 % is very high. The present invention can be used in recycling, and in case of its use in the new production process, it will provide more efficient operation for the companies that continue production as a result of the reduction of lost leakage.

The mining sector is a sector that works at very high costs. In order to feed new ore to the plants, problems should be solved and expenses regarding the investment, fuel, energy transport, labor, and the environment must be met. Due to the present invention, it is possible to recover the leakage in processed ready - made material (waste) at the lowest costs, without the said costs.

On the other hand, because the table of the invention is very easy to adjust, there is less need for the technical work labor which is hard to find due to the working conditions of the mine sites. In addition, due to the working principle and technical features of the table, failure, maintenance, and consumables expenses have been reduced.

Detailed Description of The Invention

The invention relates to a chromium separator unit (100) which is provided to allow the simple, fast and numerical adjustment of the angle in the desired direction (forward and side) of the mine separation tables with a single control arm, according to the changing mine flow, without the need for any equipment. This adjustment lever ensures that production output is sustainable and reproducible. The invention, as its main feature, is a chromium separator unit (100) that recovers the mine leakage in the waste in the chromium separation plants and has manual or automatic angular movement feature in multiple axes, which has a main body (101 ), comprising of a movable table (110) configured on said main body (101 ) and a drive group (200) that acts on said table (110). The main novelty as a feature of the said invention is that it comprises an angular motion unit (300) with a manual or automatic drive, consisting of an X - axis rotational motion bearing (305) providing angular motion adjustment through the said table (110) via the moving frame (308) and a Y - axis rotational motion bearing (306) providing rotational motion on a different axis. In addition, it has a drive unit (200) having a transmission box unit (202) configured on the same moving frame (308) as the said table (110). Moreover, it includes a suspended rope mechanism (500), one end of which is connected to the moving frame (308) and the other end is connected with the table (110) and which provides swinging motion to said table (110).

All adjustments made on the said table (110) were made with measured values rather than by eyeball estimation. It is possible to measure the angles of all dimensional values of the adjusted table (110) both analog and digitally. Due to the numerical values provided by the system, a semi - autonomous system has been created by largely eliminating the operation of the tables (110) depending on the user initiative or experience. For example, according to the tenor of the mineral, the front slope of the tables can be adjusted as 1 degree and the side slope as 2 degrees with a single instruction of the production engineer, and all tables can be brought to the same position and operated in a standard way.

The said angular motion unit (300) has a manual or automatic propulsion unit

(301 ), and the said propulsion unit (301 ) has a vertical motion shaft (302), where rotational motion is applied by means of a manual lever or motor, and this vertical motion shaft (302) has a centered motion bearing (304).

The system has a plunger (303) which is connected with said motion bearing (304) and is driven by the rotational movement it receives from the vertical motion shaft

(302). There are bearing shafts (307) centered on the X - axis rotational motion bearing (305) and the Y - axis rotational motion bearings (306) which provide rotational motion on a different axis. In addition, indicators (309) that display the distance settings of the angular movement unit (300) that produces movement in the tail part (A) and the angular movement units (300) that produce movement in the head (B) are configured.

Also, an extra 3 % slope to the section at least 50 cm wide, which is located at the end of the mineral washing area of the table was given. Due to this slope, clean concentrate leaves the table (110) faster and creates room for the incoming product. On the surface of the table (110), there is an inclination line (106) and the slant (105) that facilitates the flow of the chromium mineral. In this way, the materials that go to leakage due to waiting and stacking between the laths are prevented.

The motor speed of the machine can be made with the driver, angle settings, spring print settings, frequency settings can be made with mechanical and servo pic control. The said table (110) contains at least one drive shaft (2032) that adjusts the stroke distance (K) in the swing motion, and the stroke adjustment unit (203) that includes the drive lever (2031 ) that produces movement of manual or automatic effective to that drive shaft (2032). The transmission box contains a spring adjustment unit (204) with a configured adjustment tray (206), spring clearance (207) and adjustment lever (205).

On the said tail section (A) and head section (B), there are fixed feet (400), which are structured on two different points on the same frame. The table and the transmission box that powered it were mounted on a single frame. In all the tilt / slope settings, the table stroke axis and the table lath axis remain constant. This prevented the mineral from mixing between the slats and going to waste.

The swing of the table (110) connection is made very comfortable with the use of a new steel rope (502) system instead of the existing mechanical and bearing system. It has eliminated parts that require lubrication and are mechanically worn. In addition, the table (110) system swinging on steel ropes (502) has reduced the load of the transmission box due to the ease of swing, and reduced the chance of mechanical failure and wear of the transmission box to a minimum. The said suspension rope mechanism (500) comprises the swing connection points (503) and the table bottom connection (501 ) which are fixed to the table (110) and movable frame (308) to make swing movement from multiple points. Along with that, it comprises the body connecting plate (504) in connection with the said main body (101 ) and a steel rope (502) configured between this body connection plate (504) and the table bottom connection (501 ). By reducing the load of the transmission box with the use of steel rope (502), the operating frequency of 360 r / min is achieved. The operating frequency in the old system is limited to max 260 r / min. The ability of the system to operate at high frequency is one of the most fundamental parameters used in the separation of fine grains.

The working principle of the chromium separation table (100) of the invention is as follows: The mineral to be subjected to separation is laid on the slats (103) via product flow ducts (102). With the slope of the table (110) and the effect of water, mud material is directed to draining pipes (109). The mineral in the mud, that is, chromium particles are directed to the mine flow surface (104) and are transported to the chromium flow duct (107) via the inclined line (106) and the slant or the inclined surface (105).

As a result of the movement produced by the drive group (200), linear swing motion is applied to the table (110) in S and S1 directions. This movement is fundamentally important for the vibration and rocking motion of the table (110). This swinging motion is provided by the suspension rope mechanism (500). The suspension rope mechanism is fixed to the table (110) and the movable frame (308) to allow swinging motion from multiple points. The angular motion of the table on the X and Y axes (110) is provided via the angular motion unit (300). Due to the device system configured in the tail section (A) of the table (110), the most accurate and applicable table angle is obtained by providing up and down movements to the movable frame (308) of the table (110). So that, by rotating the vertical movement shaft (302) by actuating the drive unit

(301 ), which is activated by a manually or automatically, the movable bearing (304) which is embedded to the vertical motion shaft (302), like the nut and screw relationship, move linearly up and down in the axis of the vertical motion shaft

(302), and provide movement to the movable frame (308) with which it is connected angularly in the X - axis by means of the X - axis rotational motion bearing (305). Likewise, the angular motion of the table (110) on the Y - axis is still operates according to the same system. Yet, the angular motion on the Y - axis is provided by Y - axis rotational motion bearings (306). The angular motion on the X and Y axis is provided from the same point and the bearings that offer this angular motion are structured on top of each other.
