Grit Classifier - SANDSEP®

Supplier: SPIRAC

SANDWASH® Grit Classifier is a highly efficient unit designed to separate grit and other pollutants from process and effluent streams.

Price Guide: POA

The design of the inlet section reduces turbulence to a minimum and creates an optimum flow pattern for efficient settling.

The solids settle in the bottom of the classifier which contains a shaftless spiral. The spiral transports the sediment slowly (speeds are kept to around 5rpm to minimise turbulence) to an included or vertical conveyor which then discharges the grit.
