BHP is proud to introduce its BAZER's Fine Screw Washer SW0900, packed with a host of features that make it reliable, robust and easily adjusted to a variety of tough applications in the aggregate, mining, cement and steel industries. 
BAZER Fine screw washer is ideally suited for removing material in application such as fines recovery, sand manufacturing, concrete reclamation, and municipal waste removal. 
Built with large, three stage gearboxes and outboard lower bearing assemblies, the units are designed for operating life and maintenance ease. BAZER's washing equipment is fabricated with heavy duty tubs, ensuring an operating life that will exceed that of the competition. 
The best feature of BAZER's washing product involves the extreme duty gearbox, designed for maximum torque, and slow speed operations. With oversize gears, these most critical components of the sand screw provide added safety for today's demanding operators
Operating Principal 
Feed material enters the feed box and is distributed into the washer's setting pool. Internal and external baffles control the feed velocity and limit water current speeds and turbulence, enabling the washers to retain fines. Lighter products such as silt, excessively fine materials and other deleterious materials do not have time to settle and are carried away with the water over the long, adjustable side and end weirs. 
The settled material is augured up the washers by the spiral flights. Additional cleaning takes place by the abrading action of the material fractions. Excess water is drained back to the pooling area as the material is conveyed up and out the upper end of the trough.
