Fine material is usually defined as 3/8" (9.5mm) and less. However, Superior's fine material screw washers will accept a maximum feed of 3/4" (19mm). In addition to minor scrubbing, the machinery is capable of removing clays, silt, and unwanted lightweight contaminants. Heavier material settles to the bottom and is augured up the tub.
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 ...
