To dewater material effectively, slurry is fed onto a steep, downward inclined screen surface at the feed end of the Dewatering Screen to achieve rapid drainage. A pool of water begins to form in the valley as material builds up on the slightly upward inclined surface.

The inclination of a Hewitt Robins dewatering screen ranges between 2-5 degrees uphill angle to give a final moisture content of around 5-15%.

Materials such as sand, gravel, crushed aggregates, frac sand, industrial sands, mineral sands, hard rock, precious metals, coal, iron ore, salt and other granular materials can be processed through a Dewatering Screen.

Hewitt Robins can supply Dewatering Screens ranging from capacities as little as 10tph up to capacities as high as 400tph. Hewitt Robins have experience in de-watering materials ranging from fine sands, crushed stones, metallic ores, slag to coal, potash, rock salt and even wood chip

Hewitt Robins dewatering screens also find specific application in pre-wetting, de-sliming and draining.
