Flow predictions within hydrocyclones
Filtration & Separation, 2001The aim of this article is to illustrate the type of internal flows that can develop within hydrocyclone separators at low and high Reynolds numbers based on the Navier-Stokes equation and the RANS-equation, respectively. The following three examples are used: a 5 mm hydrocyclone; a 76 mm Rietema hydrocyclone; and a 250 mm hydrocyclone with different ...

The efficiency of a 4 inch hydrocyclone was studied using a suspension of fine silica at pulp. densities of up to 507o solids by weight. The variables manipulated were diameter of the vortex finder, flowrate, percent solids in the feed and cyclone length. Slurry temperature was also measured.

Experimental hydrocyclone roping models
Chemical Engineering Journal, 2000Abstract Hydrocyclone roping has not been studied and modeled in true grinding circuits. The paper discusses experiments made with a pilot size closed grinding circuit treating 0.5–1.0 t/h crystalline limestone. The equations found in the literature did not all describe roping very well.

Design and modelling of hydrocyclones and hydrocyclone networks for fine particle processing
Minerals Engineering, 1993Abstract An overview of the development of an integrated experimental and theoretical approach to the modelling of individual and multiple-hydrocyclone-networks is described. This methodology seeks to overcome some of the inherent limitations of previous experimental investigations by employing novel on-line and in-situ measurement technology ...

Automation in Hydrocyclone Operations
IFAC Proceedings Volumes, 1989Abstract Automation of a hydrocyclone, used as a classifier, is discussed. Instrumentation, developed for a successful automation is identified as monitoring and control instruments, are connected to a microcomputer. The instruments were designed to transmit and receive signals to operate servo-mechanism which in turn aided in automation.

Hydrocyclones in dewatering circuits
Minerals Engineering, 2003Abstract When hydrocyclones are used in dewatering circuits it is important to know the potential impact of trying to balance the flow of liquid to the overflow and underflow streams and the size distribution of the solids in these respective streams.

1992
Hydrocyclones have been evaluated and designed mainly in terms of the “Separation Efficiency” or the “Cyclone Number”. As a result, the hydrocyclone is less effective in thickening.
