Hydrocyclones
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.
Desanding Hydrocyclones
The feed stream, containing high amount of solids/ sand, enters the hydrocyclone through a tangential inlet under a pressurized condition. This is where it is forced into a spiral motion by the hydrocyclone's internal profile. The internal conic shape of the liner causes the spinning/ swirling effect to accelerate {which effectively creates ...

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.

Basics of a Hydrocyclone
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.
HydroSpin™ Hydrocyclones
Single Hydrocyclone models can handle flow rates from 1 GPM to over 8,000 GPM. Multiple hydrocyclones may be installed on a manifold to handle higher flow rates. A 1" polyurethane model can achieve cuts below 5 microns at 50 PSI feed pressure. Special oil/water separating Hydrocyclones are also available.
Effect of changes in the feed duct on hydrocyclone performance

What is a hydrocyclone used for and how does it work?
A hydrocyclone consists of a cylindrical top with an offset feed inlet pipe, an overflow outlet on top and tapered cone(s) leading down to a small outlet on the bottom. Other parts include external casings that contain the internal pressure and are clamped or bolted together, and internal replaceable liners for wear resistance.

An experimental investigation on hydrocyclone underflow pumping
The flow stream in a hydrocyclone is usually controlled by changing the geometry, especially the apex size (shown in Fig. 1).Changing the apex size changes the underflow capacity and therefore the solids concentration and the separation cut size [22], [23]mercial hydrocyclones are often supplied with several replaceable orifice sizes …
