Screw classifiers and improving sand washing efficiency

Sand screws employ the Archimedes screw principle to achieve dewatering of your sand product. The operation of the screw pushes the sand fraction up the elevated chamber while the water and the finer particles fall to the overflow weir. The sand product is typically discharged with between 23% to 25% moisture content when processing finer material this number can be
