Cyclones - Visual Encyclopedia of Chemical Engineering

In general, cyclones use centrifugal force to separate particles in a gas or liquid stream. In hydrocyclones, liquid is the fluid medium. There are two design classifications for cyclones. Uniflow or swirl tube cyclones are designed so that the clean gas or liquid leaves the cyclone in the same direction that the inlet gas flows.

Hydrocyclone - Wikipedia

A hydrocyclone 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...
