Fine Material Screw Washers for Sand and Gravel

McLanahan screw washers provide a low-cost and lowest kW power choice over many other washing choices. Featuring multiple rising current water injection points for better fines removal, longer screw shafts for better dewatering, and extended wear shoes that protect more of the spiral flights that are close to the pipe shaft, these screw washers are designed to be easily maintained, simple to use and provide years of dedicated service.

Fine Material Screw Washers

Screw Washers are an effective way to wash, de-water, de-slime material as large as 10mm or 3/8” or smaller and control the bottom end of the gradation. A large pool area provides maximum retention of desirable product sizes, while a rising current system floats off the excess “fines”. Advantages: Simple to operate, limited maintenance and low power consumption.
