Les hydrocyclones peuvent être disposés seuls, en batteries linéaires ou plus généralement, en batteries circulaires. Le principe de l'hydrocyclonage repose sur l'injection tangentielle, sous pression, d'un mélange de solides et d'un liquide dans la partie cylindrique de l'hydrocyclone.
A hydrocyclone is a filtering device, but it is widely used where a filtration action is required. Upstream of a filter, the hydrocyclone will have the advantage of eliminating the largest particles and thus protecting the filter by reducing its maintenance and cleaning.

Classification by Hydrocyclones. June 9, 2021 by Ames. Classification is defined as the process of separating a mixture containing particles of different sizes into two streams, one containing coarse particles and the other containing fine particles. Screens and cyclones are both classifiers but are governed by different principles.

Hydrocyclones can be considered as a filtration system different from the most common physical filtration systems, such as media filters (deep filtration at low velocity), disc filters or screen filters (superficial filtration).. Hydrocyclones, or also called cyclones, are equipment designed for the separation of solid particles in liquid mediums and have numerous …
Hydrocyclones Benefits: When feed slurry enters the hydrocyclone under pressure that creates high centrifugal forces, particles coarser than the "cut point" size migrate into a primary vortex adjacent to the wall and move forward to discharge with a small volume of water via the spigot. Particles finer than the "cut point" size migrate ...

A hydrocyclone is ultimately a proportional separator. Any single type of hydrocyclone will separate a given percentage of oil droplets of a certain size for a given set of process parameters. This is the profile of the hydrocyclone. It is thus essential at all times to minimise any possible causes for droplet shear.
A hydrocyclone, also known simply as a cyclone, is a centrifugal device with no moving parts. It can be used to concentrate slurries, classify solids in liquid suspensions, degrit liquids, and for washing or cleaning solids. A hydrocyclone can perform ultrafine separations and handle large-volume feed streams with high solids loading.

Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be. The separation point is the size at which a particle has a 50-50 chance of reporting either to the underflow or overflow. When the pressure is below the target pressure, the d50 will be coarser than desired.
