Hydrocyclone Wikipedia

A hydrocyclone 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 and coarse particles, and low for light and fine particles. Hydrocyclones also find application in the separation of liquids of different densities. A different description: A hydrocyclone is a mechanical device designed to reduce or

The equations of motion governing the flow in the hydrocyclone have been derived from laminar flow theory. Turbulence has been considered from the point of view of two mixing length theories, and the equations of motion have been modified to allow for turbulence. Approximate techniques have been developed to solve the resulting equations, and solutions are presented for the two turbulence

01-01-2015· In a hydrocyclone, a slurry enters through a tangential inlet, giving rise to a vortex in the stationary body. The particles and fluid are accelerated centrifugally and separation occurs in the radial direction. Denser materials migrate to the outer wall of the hydrocyclone chamber, while less dense materials move toward the inner axis.

Advances in the Theory and Practice of Hydrocyclone

As the solids concentration in the feed increases, the combined overflow of all the hydrocyclones in the battery is throttled. At the same time, the feed pump speed is increased. In this way, while the total throughput remains constant, the volume split changes to effect that more solid material is discharged in the hydrocyclone underflow.

Cyclonic separation Wikipedia

Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets of liquid from a gaseous
