Coarse Material Washers

Eagle Coarse Material Washers provide light to moderate scrubbing and washing to remove the soluble clays and dust coatings found in natural and crushed stone applications. Corrugated paddles cut through the slurrified material, which results in particle on particle scrubbing that causes the coatings to separate from the coarse aggregate. The action of the paddles combined with the rolling and tumbling generated by the rotating spirals releases deleterious materials into the overflowing wastewater. A rising current manifold on each Eagle Course Material Washer provides an upward current of water to assist in removing unwanted materials. Light-weight deleterious materials such as twigs, sticks and coals are floated by the rising current of water and the jigging action of the paddles within the tub. They are then removed by the overflowing wastewater.

By adding more paddles to the conveying shaft(s), each washer can be configured to meet the different specific scrubbing needs of various materials. Additional paddles allow material to be retained in the tub area for additional scrubbing.
