An apparatus for deflashing work pieces includes a pivotable treatment chamber, a throwing wheel which propels particulate media to impact work pieces in the treatment chamber, and a cryogen supply introducing a flow of cryogen to embrittle work pieces in the treatment chamber. A recirculation system includes a separator in communication with the treatment chamber through a plenum chamber, a media hopper in communication with the separator, first and second withdrawal conduits, a supply conduit connecting the withdrawal conduits to the throwing wheel, and a blower connected to the withdrawal and supply conduits for moving gas therein. The first withdrawal conduit is connected to withdraw cryogen gas from the treatment chamber through the separator and the media hopper and pull media from the separator to the media hopper. The second withdrawal conduit is directly connected to the plenum chamber to withdraw gas therefrom.
