Fine Material Washers

The Eagle Fine Material Washer has three related functions: washing, dewatering, and classification.

WASHING is the primary function and is accomplished by the continuous rotation of the conveyor shaft and the velocity of the overflowing waste water acting on the feed material. The rotating shaft causes the feed material to roll and tumble, which in turn provides particle on particle attrition. This action allows deleterious coatings to be removed from the sand product and discharged with the overflowing waste water.

DEWATERING is achieved by conveying the product up an inclined tub to allow the free water to drain from the material. Using a close-clearance curved plate on one side of the conveyor shaft and a drainage trough on the other side, water is allowed to drain from the product as the spiraled shaft delivers the material up the inclined curved plate. This process means less water and results in a drier final product that is more salable.

CLASSIFICATION is achieved by adjusting the volume of water over the adjustable-height weirs. For maximum material retention, the washer's three adjustable weirs are set level to provide a low overflow velocity. For coarser mesh hydraulic splits, the adjustable-height weirs are offset to provide a higher overflow velocity.
