Ask for price### 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.
