Theoretical Predictions of Migration Probabilities of Liquid
Abstract: Based on Bloor Inghams approach for determining the fluid field and on the analyses of loci offluid particles inside hydrocyclones, analytical models are developed for calculating the migration probability ofsingle cone and two cone hydrocyclones separating light dispersions.
The size and shape of the vortex finder, the shape, of the chamber into which the feed liquid is injected and the geometry of the feed inlet all dictate the details of the flow pattern which will often include recirculatory streams (see Figure 5).. Due to this complexity many authors have produced correlations for both the separation efficiency and the pressure drop in hydrocyclones.
Operationally, hydrocyclones are good at removing solids with diameters of approximately 35 μm and larger. A major drawback of hydrocyclones is that during upsets in flow or pressure drop, the rotary motion in the cone may be interrupted, possibly causing solids to carry over into the overflow liquid.

The velocity profiles of hydrocyclones were first measured by Kelsall , he found that the tangential velocity increased to a maximum from hydrocyclone wall towards the center, and then decreased rapidly. Some studies agree on the same qualitative flow be havior [11,12]. Owing to a strong air core in the center,
Weir Minerals recently celebrated the 20 year anniversary of an iconic brand the Cavex hydrocyclone. According to the company, a team of engineers at Warman International in Australia began a project in 1996 to develop the "next big thing" in hydrocyclones.
Hydrocyclones are ideal for recovering down to 400 mesh (38µm) particles of 2.7 SG. This is typically done in the form of an Ultra Fines Recovery system comprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90% passing 400 mesh (38µm) and a product discharging the screen in a drip free, readily conveyable and stackable form.
