ABSTRACT:
A mill (10) according to the preferred teachings for grinding garbage is disclosed including an octagonal shaped grinding chamber (26) formed by side plates (14-17) interconnected to have a square cross section with its corners closed by corner plates (20-23). Planar shelves (32, 34, 36) having centrally located apertures (38) divide the grinding chamber (26). Grinding rotors (48-50) are rotatably fixed to a rotatable shaft (44) and are located complementary to, parallel, and above the shelves (32, 34, 36). The grinding rotors (48-50) include planar arms (64) which radially extend from and are circumferentially spaced on a planar disc (54) fixed to the shaft (44). An impeller rotor (51) is also rotatably fixed to the shaft (44) below the grinding rotors (48-50) and includes angle iron arms (76) which radially extend from and are circumferentially spaced on a planar disc (54) fixed to the shaft (44). The arms (64) of the grinding rotors (48-50) may include pusher bars (96) located on top of the arms (64) and within the radial extent of the discs (54) and/or may include flap blades (88) located on the bottom of the arms (64) intermediate the discs (54) and the centrally located apertures (38) of the shelves (32, 34, 36). The radial spacing between the free ends of the arms (64) and the grinding chamber (26) and between the discs (54) and the centrally located apertures (38) and the axial spacing between the grinding rotors (48-50) and the shelves (32, 34, 36) decrease from the grinding motor (48) adjacent the inlet opening (40) of the grinding chamber (26) to the grinding rotor (50) adjacent the outlet opening (42) of the grinding chamber (26).
