Abstract:

A mill is described for progressively shredding material such as garbage, tires, aluminum cans, waste paper, etc. into loose particulate material. The mill includes a hopper that is movably mounted to a shredding wheel frame. The hopper includes an open bottom end into which the shredding wheel projects. The hopper is driven to reciprocate along a straight path over the wheel to bring the contained material into wheel contact. Provision is made to vary the depth of cut taken by the wheel in response to loading conditions of the associated drive motor by automatically adjusting a feed grate mechanism relative to the wheel.
