Wet Classification Equipment

Wet classification is performed by filtration, settling, centrifugation, Sind hydrocyclones. When operated in conjunction with grinding equipment, the wet classification equipment must operate continuously and give a pumpable fluid. This is often accomplished in practice with hydrocyclones because the other methods are unsuitable (e.g., settlers and centrifuges are used for dilute suspensions, filters and screens produce a nonpumpable cake.) 

Two other dimensionless equations describe the operation of Rietema s hydrocyclones. 

The size selectivity, SS(d), of these types of hydrocyclones is given either by L3mch and Rao [45]
