Abstract
A grinder for comminuting waste material comprises a frame structure (18, 20). A grinding rotor (24) is rotatably carried by the frame structure (18, 20.) The grinding rotor (24) carries a plurality of cutting tools (36) cooperating with a counter blade (26, 28) carried by the frame structure (18, 20). Two plate chain conveyors (68, 70) are vertically aligned so that working runs (80, 120) thereof form a converging moving wall funnel positively feeding pieces (146, 148) of material to be comminuted towards a grinding unit (12) formed by the grinding rotor (24) and the counter blade (26, 28).
