ABSTRACT:
A garbage disposal unit including a frame mounting a drive motor and a garbage disposal. The garbage disposal has a separable housing which mounts a hammer assembly over a perforated screen assembly. The housing has a cylindrical annular side wall closed at opposite ends by removable end plates to define a grinding chamber. The screen assembly slides into the bottom of the grinding chamber between breaker bars carried by the annular side wall and is retained in position by the end walls to separate the grinding chamber inlet from the outlet. The holes through the screen plate of the screen assembly cooperate with the hammers on the hammer assembly to comminute the garbage as the hammers are rotated thereby. The holes are staggered to maximize the comminution cooperation between the hammer assembly and the screen assembly with the hammers being staggered axially and circumferentially so that the hammers rotate in separate cutting planes axially spaced from each other.
