Hydrocyclone - Wikipedia

A hydrocyclone (often referred to by the shortened form hydroclone or 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.

Understanding the Hydrocyclone Separator Through ...

Apr 01, 2003  Understanding the Hydrocyclone Separator Through Computational Fluid Dynamics. The hydrocyclone provides an efficient means for solids separation from suspension, de-watering or purification, but there is little detailed understanding of the swirl flow and separation mechanism prevailing within the device.

May 01, 2004  The presented hydrocyclone CFD predictions have provided a novel understanding of the development of the initial flow field. Alongside the expected tangential velocity profile (`hat-type' vorticity, Alekseenko et al., 1999 )), novel predictions of asymmetry and of the transverse and axial velocity profiles have been obtained.

The Sizing Selection of Hydrocyclones

HYDROCYCLONES By Richard A. Arterburn For many years, hydrocyclones, commonly referred to as cyclones, have been extensively utilized in the classification of particles in comminution circuits. The practical range of classification for cyclones is 40 microns to 400 microns, with some remote applications as fine as 5 microns or as coarse as 1000 ...

Cyclones - Resource Book

HydroCyclones A typical hydrocyclone consists of a conically shaped vessel, open at its apex (spigot), or underflow, joined to a cylindrical section, which has a tangential feed inlet. The top of the cylindrical section is closed with a plate through which passes an axially mounted overflow pipe.

Hydrocyclones McLanahan

Hydrocyclones are ideal for recovering down to 400 mesh (38µm) particles of 2.7 SG. This is typically done in the form of an Ultra Fines Recovery system comprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90% passing 400 mesh (38µm) and a product discharging the screen in a drip-free, readily conveyable and stackable form.

Hydrocyclone Working Principle

Aug 06, 2015  Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones
