ABSTRACT:
Apparatus for reducing waste material in which substantially parallel shafts carry cooperating material reducing cutters for either direction of rotation of the shafts. There are selectively positionable cages at the discharge with comb teeth in position to cooperate with the cutters in either direction of cutter rotation, and there is a control system for operating the cutters and cages such that for normal reduction of waste material the cutters are rotated in a first direction and the cages are positioned to produce a desired size of reduced waste material, and the cutters are rotated in a second direction while the cages are positioned to release non-reducible material.
