Particles finer than the "cut point" size migrate into a secondary upward-moving vortex, along the axis of the hydrocyclone and discharge with the majority of the water. Hydrocyclones are limited in being able to dewater fine solids to a conveyable state Dewatering Screens are used to further dewater Hydrocyclone underflow.

The separation efficiency is a crucial parameter to appraise the separation performance of hydrocyclones, which is referred to the particle recovery in the underflow. And, the particle recovery in the underflow is defined as the quantity ratio of particles discharged with underflow to those feed into the hydrocyclone for the same particle size.

The main parameter of a hydrocyclone is its diameter, i.e., the inside diameter of the cylindrical feed chamber. This diameter can range from 10 mm to 2.5 m in commercial hydrocyclones, capable of separating particles of sizes ranging from 1.5 to 300 μm (and densities of approximately 2700 kg/m 3 ).

Cyclones have four main sections: feed chamber, cone (body), underflow (spigot liner or apex), and overflow (vortex finder). The feed chamber is designed to guide the slurry into a spiral, creating a vortex. The cone (body), which can be one piece, or multiple pieces, allows the material to continue spiraling, generating a centripetal force.

A Hydrocyclone, or commonly called a cyclone, is more widely known and used. The ideal condition for a cyclone is steady feed in regard to flow rate and solids. The steady flow rate is essential to maintain the desired pressure to make the predictable and repeatable separation. Changes in the flow rate have a direct relation to the inlet pressure.
