This twin rotary indexing wet slurry blast system is fed by a pick and place robot. It uses ceramic media to wet blast pure silver 5 oz. numismatic coins and provides a uniform cosmetic finish. This system wet blasts, closed loop rinses, and dries the coins, ready for boxing and shipment. In service at the United States Mint, Philadelphia, since 2011.
