  • Patent number: 6224463
    Abstract: A preferred embodiment of a workpiece finishing system impinges a grit and fluid slurry onto a workpiece and then recycles the slurry for subsequent reuse. In another aspect of the present invention, a recovery tank is used for generally settling and concentrating the grit in the slurry, and for separating out a portion of the fluid from the grit. A further aspect of the present invention provides a venturi-type nozzle for expelling the grit and fluid onto a workpiece, wherein the nozzle has a selectively movable inlet thereby varying the slurry concentration properties of the nozzle.
