ABSTRACT:
A grinder for dry waste materials includes a vertically-oriented, cylindrically-shaped housing having an opening at its upper end for receiving materials to be comminuted. The shredder element has upwardly-extending impeller blades disposed on its upper surface. The outer perimeter of the shredder element is separated from the inner wall of the housing sufficiently to provide a gap through which comminuted materials can drop from the upper chamber to the lower chamber of the housing. The interior of the upper portion of the housing is provided around its circumference with diverget blades that are angled downwardly in the direction of rotation of the shredder element. The lower housing has a closed bottom and a tangentially oriented discharge element for discharge from the lower housing of comminuted materials. The shredder element has downwardly-extending paddles on its lower surface that extend downwardly into the lower housing and are adapted to sweep the lower housing, act as an air blower and expel comminuted materials therefrom. Optionally the shredder element is flattened on opposite sides, to provide enlarged openings for movement of comminuted materials from the upper chamber into the lower chamber. The upwardly-extending impeller blades may optionally be Z-shaped.
