ABSTRACT:
A tapered auger shredder which includes a frame defining a grinding chamber with a front wall having a centrally-located discharge opening and a rear wall mounting a powered auger screw having a flighted shaft extending through the chamber and into the discharge opening. The auger screw and shaft are tapered and the screw flight is correspondingly tapered so that the volume pumped by the screw along the length of the shaft remains substantially constant, or the rate of compression is substantially reduced, to provide consistent flow of material to the discharge opening and reduce build up of material against the front wall. In a preferred embodiment, the screw includes a torque transmission collar which extends between a disc-shaped base plate supporting the screw and the first flight turn and acts to prevent jamming of material between the base plate and underside of the first turn as well as transmit rotational torque from the disc to the shaft and flight.
