Specs
Classify, Scrub and Dewater
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.
As it proceeds up the incline, water drains from the material and is eventually discharged with a moisture content of 15-25%.
If you don’t have time or space to stockpile and dry this material, many producers pair with a dewatering screen to remove half of that moisture. Better yet, the Aggredry Dewatering Washer is all processes in a single machine.
