Small-diameter hydrocyclones: Performance prediction by empirical
Empirical models are now used for predicting the performance of hydrocyclones in terms of capacity, cut size (d50,c), water split and partition curve. These models (such as the model by Lynch and Rao and the model by Plitt) were developed and checked for hydrocyclones with diameters larger than 4 in. However, for smaller-diameter hydrocyclones, little empirical …

Bradley Hydrocyclones: Design and Performance Analysis
Hydrocyclones are an important class of solid/liquid separation equipments. In this work, three Bradley hydrocyclones with 15,30 and 60 mm diameters were used. Aqueous suspensions of calcium carbonate, with volumetric concentration ranging from 0% to 10% were tested. Based on the experimental results, it was possible to obtain correlations for the product between Stokes …

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 number an optimum cyclone design can be found. …
