## Hydrocyclone - Wikipedia

A hydrocyclone (often referred to by the shortened form hydroclone or cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles. Hydrocyclones also find application in the separation of liquids of different densities.

## Hydrocyclone Separator | Multotec

In a hydrocyclone, cut size is the separation point between particles deemed to be ‘coarse’ and ‘fine’. If a particle is at the cut point size, it will have a 50% chance of reporting to either the overflow or underflow. Any particle size greater than the cut size is deemed a coarse particle and will exit via the underflow. Fine particles – those less than the cut point size – are discharged via the overflow.
