<p>A preferred embodiment of a workpiece finishing system (21) impinges a grit and fluid slurry onto a workpiece (35, 35') and then recycles the slurry for subsequent reuse. In another aspect of the present invention, a recovery tank (25) is used for generally setting 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 (23) for expelling the grit and fluid onto a workpiece (35, 35'), wherein the nozzle (23) has a selectively movable inlet thereby varying the slurry concentration properties of the nozzle.</p> |
