Screw classifier is an ordinary washing system having less consumption of water. Screw rotates on low rpm drive through the gear motor. Screws have hard phased lines or wear resistant plates to prevent abrasion of metal as this washing system is widely used in highly abrasive material like silica sand and quartz. As usual it is an ordinary system hence giving less production capacity and lower efficiency. To get higher recovery of sand blenders are used to transform silt or fine sand within the water, thus percent efficiency can be increased.
