Downdraft shredder

摘要

A downdraft shredder comprising a lower housing, a semicircular lower grate, a chute for supplying material to a rotor cavity and a hood for covering the remainder of the rotor cavity. A rotor with hammers is rotatably mounted in the rotor cavity and draws material from the chute against the lower grate for shredding the material. A plate extending in the hood from the rotor cavity to a back corner of the hood, allows air entrained by the rotor to stabilize thereby preventing an updraft of air through the chute. This produces a true downdraft shredder which represents a modification over known shredders.
