Abstract: A vibratory apparatus for removing particulate materials from an object includes a container having a curved inner surface disposed about a generally horizontally extending longitudinal axis, the container being resiliently supported above a base. A plate is disposed in the container with a first edge spaced from the curved surface of the container and a second edge proximate to the curved surface of the container, the plate having openings therethrough. A vibration generator produces a vibratory force to cause the object and media within the container to be moved in a generally rising and falling path of rolling movement along the curved inner surface, the motion of the object being impeded by the plate while the motion of the media is not impeded by the plate, the media instead moving through the openings in the plate.

Abstract: An apparatus includes a separation deck free of stepwise changes in elevation between a first end and a second end, the separation deck comprising a plurality of spaces through which a constituent material may pass, a plurality of scrubbers disposed on the deck, the plurality of scrubbers having a first end disposed at a higher elevation than the deck in at least a first state, and a vibratory generator coupled to the deck. The mixed material moves over the deck and the scrubbers from the first end to the second end by the motion imparted by the vibratory generator. Components of the mixed material move 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.
