Kind Code:
B2
Abstract:
The present invention relates to a method and apparatus for crushing a mineral material. Then, the mineral material is delivered in a crushing space (6) towards crushing means (8), whereby at least a portion of the material flow is discharged via a screen (20). The remaining mineral material is arranged to meet transfer and screening as well as crusher drums (10, 11) provided in the crushing space such that the transfer and screening drum continues pre-screening while simultaneously transferring the mineral material towards the crusher drum (11). Finally, the mineral material remaining in the crushing space is by crusher blades (19) of the crusher drum (11) subjected to mechanical machining wedging the mineral material against a crusher plate (21) and decreasing the particle size thereof in order for the mineral material to be finally crushed into a particle size to be discharged from the crushing space.
