ABSTRACT:
A process for grinding materials comprises driving a plurality of unground particles in a grinding zone in a predetermined direction, abruptly reversing the direction of motion of part of the particles in a subsequent grinding zone so that they impact with each other and reversing the direction of motion of the particles as they pass from one grinding zone to the next, until the size of the particles is reduced to the desired level. A grinder for carrying out such process essentially comprises first and second rotors, the first rotor being provided with a plurality of first perforate members and the second rotor being similarly provided with a plurality of second perforate members alternately arranged between each pair of first perforate members. The first rotor is rotatable in a predetermined direction, while the second rotor is rotatable in the opposite direction. Material is discharged within the central portion of the rotors; and discharge device is communicated with the periphery of the rotors, so that the material fed to the innermost perforate member of one of the rotors is centrifugally thrown towards the innermost perforate member of the other rotor through the bores thereof and so forth, in order to repeatedly reverse the direction of rotation of the material and cause the particles to impact with each other in order to effect a grinding action.
