ABSTRACT:
A stationary cutting plate is releasably secured about an annular joint between a base housing and a housing extension. The plate overlies a cavity in the housing which serves as a receptacle for cut particles. The housing extension is hollow to provide a feed chamber above the plate. A free-standing partition extends upwardly into the extension from a ring which is supported by the upper surface of the cutting plate. The plate has scoop-shaped cutting elements which are distributed about imaginary concentric circles emanating from the plate center axis. Even numbers of the elements are unevenly spaced-apart along respective circles but are diametrically opposed from each other. A slotted driver implement is used to engage the partition and cause its rotation for lateral movement of feedstock into the cutting elements. The implement is also used to simultaneously push the feedstock downwardly against the cutting elements.
