Classification and centrifugation | FLSmidth

A cyclone, also known as a hydrocyclone, is a centrifugal device with no moving parts. It can be used to concentrate slurries, classify solids in liquid suspensions, de-grit liquids, and for washing or cleaning solids. A hydrocyclone can perform ultra-fine separations and handle large-volume feed streams with high solids loading.
