ABSTRACT:
This disclosure deals with apparatus for grinding kitchen wastes or garbage into particles sufficiently small that they may be carried away by ordinary sewage facilities. The apparatus includes means forming a passage into which the wastes are disposed, a spirally grooved or screw-shaped member rotatably mounted in the passage, a pair of grinding members mounted at the outlet of the passage, the grinding members being movable relative to each other and forming a waste receiving space therebetween, and impeller means in the space for moving waste from the passage into the space. The screw-shaped member both shreds the waste and moves the wastes through the passage. The grinding members grind the waste between them into a paste-like consistency and the impeller also shreds the waste.
