ABSTRACT:
A pulverizer device is provided for pulverizing food, garbage and the like. The pulverizer includes a housing with a centrally disposed, rotatable shaft carrying a plurality of cutting and grinding stages which cooperate with opposingly mounted cutting and grinding counterparts to sequentially pulverize the material. In order to accommodate a simple to manufacture and easily adjustable modification of the pulverizer device so as to be usable with both garbage and the grinding of certain food stuffs such as grain and spices, there is provided a manually adjustable annular ring mounted at the lowest stage of the pulverizer. A handle protrudes outwardly through a housing wall slot to accommodate rotation of the ring to effectively raise and lower the same to engage and disengage the last pulverizing stage. A closure flap with a weighted end is pivotally mounted at the inlet to the pulverizer housing to maintain the inlet in a closed position in the absence of incoming material to be pulverized, to thereby prevent escape of noxious fumes.
