Abstract
Apparatus for fragmentizing objects recovers and reprocesses oversized fragments. A shredder is encircled by an annular trommel revolving about a horizontal axis of rotation and which extends over the shredder intake hopper and below the fragment outlet. Fragments which are too large to pass through apertures in the trommel are carried upward by vanes on the trommel and returned to the intake hopper. In one form of the apparatus, a fragment guide has a curved surface extending along at least a lower portion of the trommel and which is spaced from the trommel to allow small fragments to pass through the trommel apertures. Cleats on the trommel urge such fragments towards a fragment discharging end of the guide. Thin elongated fragments which attempt to pass through a trommel aperture are stopped by the presence of the guide and thus are also carried upward and returned to the intake for further processing.
