Separation Par Hydrocyclone

The hydromechanics in a hydrocyclone with an injector is investigated on the basis of the performed experiments and mathematical modeling. Special emphasis is placed on elucidation of the mechanisms of action of injection on the restructuring of hydrodynamic fields and finally on the mechanisms of classification of particles in the hydrocyclone.

Hydrocyclone separation performance can be explained by a simple force balance on individual par-ticles entering the device during steady-state operation. As the flow rate increases, larger particles experience more centripetal force inside the hydrocyclone, are forced to the wall, and eventually exit the device through the underflow.

Hydrocyclones. The basic principle of separation by a hydrocyclone is similar to that of a centrifuge. In a hydrocyclone, the liquid is forced into circular motion due to tangential injection of the oil/water mixture against the circular configuration of the hydrocyclone (Yu and Ventriglio, 1969) .

Multiple investigations on hydrocyclones have been carried out since the 1950s (Kelsall, 1952). Now a commonly accepted wisdom is that the separation characteristics of the hydrocyclone depend on the flow field, and turbulence intensity of which has a major impact on hydrocyclone’s classification efficiency (Teja et al, 2014).

HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of pre-concentration of minerals – mainly the production of a high weight, low assay product, which may be rejected as waste. In principle it is the simplest of all gravity processes and is a standard laboratory method for separating minerals of different specific gravity.
