performance analysis and design of filtering hydrocyclones - SciELO

Aiming at combining two separation processes, researchers in the Chemical Engineering Department at the Federal University of Uberlândia proposed a modification of the conventional hydrocyclone. (Barrozo et al., 1992). The conical section of a hydrocyclone of Bradley's design was replaced by a conical filtering wall.

Performance and design of hydrocyclones—III: Separating power of ...

A new theory on the separation in hydrocyclones is developed on the basis of the dynamic behaviour of the particles to be separated. This theory leads to the derivation of a dimensionless cyclone separation number, which—as experiments have confirmed—is only dependent on the shape of the cyclone. With the aid of this...

Hydrocyclones were originally designed to promote solid-liquid separations but nowadays they are also used for solid-solid, liquid-liquid and gas-liquid separations. Although a hydrocyclone is a very simple equipment to build, the use of custom-made cyclones is not widely used. This is probably due to the lack of a simple...

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 (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine...
