Abstract

An auger system adapted to shred large materials. An exemplary embodiment is comprised of dual opposing augers that are adapted to grab, compress, and shred the material, reducing the material size such that it may be discharged through a side outlet opening and/or an extrusion tube into, for example, a standard roll-off compaction container. An exemplary embodiment allows large material to be processed in a low speed device with reduced equipment dimensions, providing operator safety with low profile loading, lower noise level, reduced chances of material being expelled from the processing chamber, and ability to use conventional material transport (e.g., semi-trucks).

Claims36

Dependent claims

A system for shredding, comprising:

a processing chamber comprised of a top, a bottom, and at least one side, said processing chamber further comprising an input opening configured to receive material to be shredded and a side discharge opening located in said at least one side that is configured to output shredded material;
a first tapered auger positioned in said processing chamber such that an axis of said first tapered auger is aligned with said side discharge opening;
and
a second tapered auger positioned in said processing chamber, said second tapered auger opposing said first tapered auger such that said material is configured to be shredded between said first tapered auger and said second tapered auger;
wherein said first tapered auger is configured to urge said shredded material forward through said side discharge opening;
and
wherein said to of said processing chamber is configured to be 10 feet or less above ground or floor level such that said side discharge opening is adapted to be aligned with an input opening of a standard roll-off container.
