Using a high pressure hydrocyclone for solids

The subject of this paper was to enhance hydrocyclone separation of cut sizes in the submicron range. For this purpose, a 10 mm hydrocyclone was operated at high pressures up to 60 bar and the suspension temperature was increased up to 50 176;C. The aforementioned batch process was used with overflow recirculation and underflow collection. 2.

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 hydrocyclones classification efficiency (Teja et al, 2014).

Hydrocyclone

A hydrocyclone (often referred to by the shortened form 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.
