Hydrocyclone Working Principle
ClassificationPurposeMechanismOperationEffectsExampleSignificanceThe third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.
Analysis of swirling flow in hydrocyclones operating under
The present study focuses on the analysis of swirling flow in hydrocyclones operating under dense flow regimes having the following objectives: • Development of a modeling scheme based on the strong foundation of physics of fluid flow and particle–fluid interactions. •
Computational study of the flow characteristics and
As the flow in the mini-hydrocyclone falls in the laminar/transitional flow regime with an inlet Reynolds number of the order of 10 2 –10 3, this study used a fine mesh to obtain a direct numerical simulation (DNS) of the flow field. The fluid flow equations for mass (Eq.
Hydrocyclone Wikipedia
A hydrocyclone (often referred to by the shortened form 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.

A high efficiency small diameter hydrocyclone for separating liquid/liquid constituents of a mixture. An effective separation portion L e of the hydrocyclone separation chamber begins at a small diameter throat D T where acceleration and velocity of the mixture cease to increase. This effective portion L e ends at the underflow outlet from the separation chamber, and has an area to volume
