Patent ID: 7506766

Claim:
An apparatus for separating a mixed material into constituent materials, the apparatus comprising: a separation deck free of stepwise changes in elevation between a first deck end and a second deck end, the separation deck comprising a plurality of spaces through which a constituent material may pass; a plurality of scrubbers disposed on the deck, each of the plurality of scrubbers comprising a cam having a first end that is movable relative to the deck such that, in a first state, the first end of the cam is disposed at a higher elevation than the deck; and a vibratory generator coupled to the deck, the mixed material moving over the deck and the scrubbers from the first deck end to the second deck end by the motion imparted by the vibratory generator, components of the mixed material moved relative to each other as the components move over the scrubbers, thereby causing the constituents material attached to the components of the mixed material to separate and pass through the spaces in the separation deck.
