TRIO's fine material sand screws are designed for dewatering, washing and classification.
WIth adjustable overflow weirs, the sand screws enable operators to control the depth of the head and velocity of overflow waste water. The large overflow feed box allows for the retention of finer mesh materials or if necessary, for the removal of those particles. All TRIO fine washers are built with large, three-stage gearboxes.
