ABSTRACT:
A method of crushing material includes the steps of feeding a first flow of material to be crushed to a rotor rotating around a vertical axis, the rotor accelerating the first flow of material towards an impact wall section, and feeding a second flow of material to be crushed into the path of the accelerated first flow of material. The second flow of material is fed in a direction having a substantially tangential component in relation to the rotor, such that the second flow of material will have a substantially tangential component of movement in relation to the rotor when reaching the path of the first flow of material. A crusher is adapted to feed the second flow of material such that it will have a substantially tangential component of movement in relation to the rotor when reaching the path of the first flow of material.
