In fact, for wet screening to separate rock from clay, the recommended water usage is the highest of any aggregate application: from 5 to 10 gallons per minute per STPH of feed to the screen. In this case, focus the water and water pressure on the top deck and add more spray bars and/or nozzles, to that deck.
