ABSTRACT:
A revolving trommel situated adjacent to a shredder has an annular screen which intercepts oversized or elongated fragments in the outflow from the shredder for return to the shredder. A first fragment guide directs the shredder outflow into the trommel and vanes in the trommel lift the oversized fragments to another fragment guide which extends out of the trommel to the shredder intake. In the preferred form, the trommel rests upon and is turned by a motor driven flexible continuous belt which carries fragments that pass through the screen upward to an elevated discharge chute. The apparatus is particularly useful for fragmentizing sterilized medical wastes.
