Hydrocyclone - Wikipedia

A cyclone is a separator separating product phases mainly on basis of differences in gravity. Cyclones can be subdivided into two main categories: dry or dust cyclones which separate solids from gasses and wet or hydrocyclones which separate solids from liquids. A hydrocyclone comprises a cylindrical shaped feed part with tangential feed; an ov
