Screw And Rack Classifier

Description

Screw Classifier is an ideal machine to wash and a separate silt and other impurities as well as dewatering sand after wash. It combines both the functions of washing and dewatering and is very effective.

It consists of a slow rotating and gently elevating spiral screw in a tub with an inclined trough and its function is simple. Water is sprayed under pressure on to sand fines in the screen, and the sand slurry is gently let into the classifier tub full of water without causing any turbulence. The silt and other impurities get floated and discharged over weirs. The coarser particles i.e. sand settle at the bottom.
