Abstract

The material processing mill includes a pair of rolls that each preferably have a smooth outer surface, such that material particles passing through the nip defined between the rolls are formed into flakes. One of the rolls is shiftable relative to the other, and shifting of the one roll is controlled by a roll positioning mechanism that includes a pair of piston and cylinder assemblies and associated spring reliefs. The rolls are each powered by a separate drive, which preferably includes a motor drivingly connected to the respective roll by a cogged belt. The drive for the shiftable roll particularly includes a motor base having a shiftable carrier to which the motor is fixed. The drive further includes a belt tensioning device, preferably in the form of a turnbuckle, that adjustably fixes the motor to the shiftable roll. Thus, the motor normally shifts with the shiftable roll, but the tensioning device may be used to adjust the spacing between the motor and shiftable roll to vary the tension on the belt. The piston and cylinder assemblies are single acting and are consequently capable of powering the shiftable roll in only one direction, and the motor base includes a biasing mechanism to urge the motor and roll in the opposite direction.
