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. Hydrocyclones also ...

The working principle of hydrocyclone is centrifugal sedimentation, when two phases or three phases mixed liquid is fed into hydrocyclone by a certain pressure liquid and produces strong three-dimensional-elliptic rotational movement. Due to the different density of particles, the centrifugal force, the centripetal buoyancy and drag force is different. So most coarse particles or ...

Hydrocyclone EMIS

To summarise, a hydrocyclone separates particles using the generated centrifugal forces. This centrifugal force is generated because the liquid enters the cyclone tangentially at high speed and is accelerated by a conical middle section. This helps to create a liquid vortex in the cyclone. The smaller the diameter of the cyclone, the greater the centrifugal force that will be generated because ...

How to resolve the most common hydrocyclone problems

The primary ways the plant metallurgist can change or alter the hydrocyclone’s classifi ion is to vary the cyclone feed dilution water or adjust the hydrocyclone’s operating pressure. Producing a finer classifi ion in hydrocyclones requires additional dilution water to lower the feed density of the cyclone, and is also achieved by raising the hydrocyclone’s operating pressure.

Hydrocyclones and Separators are selected based on several parameters, including volume of flow, tons per hour of recoverable material and cut-point required. Larger units process higher volumes; however, the larger the Hydrocyclone, the coarser the cut. Therefore, processing a larger volume of slurry with the need to recover finer fractions would lead to the selection of several smaller units.
