Hydrocyclone is mainly used in mineral processing as a classifier and has proved extremely efficient at fine separation sizes. Hydrocyclones is also called cyclone separator, Hydrocyclones include hydrocyclone desander (10inch cone) and hydrocyclone desilter (4" cone), which is used to separate sand and silt from the drilling fluid. Centrifugal pump is used to pump the drilling fluids from mud tank into the set of hydrocyclones.
