Screw sand washer
1. Introduction
Sand screw washer is used primarily to process crushed stone and gravel, with the range from 3mm up to 100mm, it effectively removes clay, dirt, dust and coatings of the crushed stone and gravel, which can not be removed by wet screening alone.
By screw washer cleaning and classifying refers to removing water soluble clay, silt, and micro sized fine sand particles typically less than 150 mesh in size.
Hydraulic separation uses water as the medium to clean and classify sand particles by weight. Larger particles weigh more than smaller particles so the larger particles sink and are collected in the bottom of the trough.
The sand particles are transported to the inclined discharge end by a double pitched steel spiral shaft equipped with replaceable polyurethane wear shoes. The smaller lighter unwanted particles are floated to the surface of the claim settling pool and are discharged over the weirs.
