Abstract

This disclosure relates to a shredder with a fluid-immersion shredding chamber and a sealing assembly for containing fluid in the shredding chamber. For example, the shredding chamber can include a plurality of shredding instruments (e.g., teeth, knives, etc.) that are manipulated (e.g., rotated, spun, reciprocated, etc.) to shred or otherwise disassemble various objects (e.g., batteries). In some examples, the shredding instruments are mounted on a shaft that rotates to manipulate (e.g., turn) the shredding instruments inside the chamber. In addition, the shaft can interface with (e.g., insert into and exit from) the shredding chamber through an opening in a sidewall of the shredding chamber, and examples of the present disclosure are directed to a sealing assembly for reducing the likelihood that fluid from the chamber might leak through the opening.

Abstract

A shredder system and methods for shredding recyclable material including a primary shredder that shreds recyclable material into a first larger shred size and a secondary shredder that shreds recyclable material into a second smaller shred size material. The secondary shredder includes a rotor and a knife that meshes with the rotor to cause all of the first larger shred size material to be further shredded to the second smaller shred size material. The secondary shredder may also include a diverter mechanism capable of diverting the first larger shred size material. Either the diverter mechanism or the knife can move relative to the rotor to create an opening that allows the first larger shred size material to avoid being further shredded into the second smaller shred size material. The shredder system may be disposed in a motor vehicle.
