Abstract:
A system for impinging a grit and fluid slurry to a workpiece, said system comprising:a nozzle having a first inlet and a second inlet;a receptacle operable to receive the slurry after the slurry is applied to the workpiece from the nozzle;a recovery tank connected to the receptacle, at least one baffle located in the recovery tank for directing the flow of the grit in the recovery tank, the grit substantially settling toward a bottom of the recovery tank;a first outlet connected to the recovery tank, the grit being operably transmitted from the first outlet of the recovery tank to the first inlet of the nozzle;a second outlet connected to the recovery tank; anda fluid pump operably pressurizing the fluid, the fluid being operably transmitted from the second outlet of the recovery tank to the fluid pump, the pressurized fluid being operably transmitted from the fluid pump to the second inlet of the nozzle;wherein the nozzle operably expels the pressurized fluid and the grit for application to the workpiece; andwherein the recovery tank operably encourages separation of the grit from the fluid of the slurry for re-use in the nozzle.
