Abstract

A shredder for reducing material which includes a conical cutting drum rotatably positioned within a housing and having an imperforate outer surface so as to carry shredded material radially with and externally of the drum; at least one cutting implement disposed about the outer surface of the cutting drum; an anvil disposed adjacent to the cutting drum; a bellyband wrapping around and conforming to the drum; and a transition interconnecting the bellyband with a discharge port and having a cross sectional configuration that inversely mirrors the cross sectional configuration of the bellyband.

Claims

1. A shredder for reducing material comprising:

a housing;

a dual conical cutting drum comprising two ends, wherein the conicals are positioned base to base so that the cutting drum tapers toward both ends, the cutting drum rotatably positioned within the housing, the cutting drum having an imperforate outer surface whereby to carry reduced material radially outwardly and externally of the drum;

at least one cutting implement disposed about the outer surface of the cutting drum;

an anvil disposed adjacent to the cutting drum; and

a drive connected to the drum.

2. The shredder of claim 1, wherein the shredder further includes a bellyband with a cavity, the bellyband at least partially wrapping the cutting drum.

3. The shredder of claim 2, wherein the shredder further include a transition disposed after the bellyband, the transition having a larger cavity than the cavity of the bellyband.

4. The shredder of claim 1, wherein the cutting drum further includes an outer surface, and a plurality of pockets disposed in the outer surface, the at least one cutting implement being a plurality of cutting blades, the pockets being positioned adjacent to the cutting blades so that reduced material can be received from the cutting blades and carried radically and externally of the cutting drum.

5. A shredder for reducing material comprising:

a housing;

a tapered cutting drum rotatably positioned within the housing and having an imperforate outer surface whereby to carry reduced material radially outwardly and externally of the drum;

at least one cutting implement disposed about the outer surface of the cutting drum;

an anvil disposed adjacent to the cutting drum; and

a drive connected to the drum.
