Abstract
The present invention is directed to a jam resistant shredder-feed device for advancing and comminuting elongate materials, such as copper wire scrap, plastic mold runners and the like. In accordance with the invention, an auger assembly is rotated within a cylindrical housing, the auger assembly advancing the materials to be comminuted toward a stationary knife or breaker. The device is characterized by the employment of one or more idler auger sections adjacent the stationary knife, the upstream and downstream ends of the idler section or sections themselves defining knives, as does the downstream end of the feed auger, the respective knife portions being preferably spaced apart in a longitudinal direction by distances slightly greater than the average thickness of materials to be processed.
