Fine Material Washers

TCI Fine Material Washers (Sand Screws) are engineered to accomplish 3 main functions: Washing, Classification, and Dewatering.

WASHING is accomplished by the turning shaft causing material attrition. This attrition allows deleterious material to be broken up and discharged with the overflow waste water.

CLASSIFICATION is accomplished by adjusting the overflow weir boards to control the waste slurry and meet the desired specification.

DEWATERING is accomplished by conveying the desired material up the inclined tub and allowing water to drain from the product.
