01-07-2014· The partition curve (Fig. 1b) used to characterize the separation efficiency of the hydrocyclones involves the mass fraction T(d) for each particle size d, which is discharged in the coarse product (underflow).Schubert and Neesse (1980) demonstrated that the typical S-shaped partition curve derives from the superposition of the settling flow and a turbulent diffusion

01-04-1999· The partition curve is used to quantify the classification in hydrocyclones. It is generally monotonic and asymptotes to a value called the bypass. A `fish-hook' curve occurs sometimes when partition values lower than the bypass are observed. A number of attempts have been made to develop fish-hook partition curve models.

07-08-2013· Hydrocyclone Efficiency Curves. The Hydrocyclone Efficiency Curves are affected by many operating factors such as feed density, apex and vortex sizes and feed pump pressure. These factors will cause your cyclone classification to operate correctly, in roping or spraying mode. Everyone knows or has seen an “Ideal Cyclone Efficiency Curve” VS,

Corrected partition curve [image 145-2-17] Reduced Efficiency Curves. Lynch and Rao (1965) found that classifying cyclone efficiencies are more easily evaluated and compared over a range of cyclone geometries and operating conditions using a Reduced Efficiency Curve. The Reduce Efficiency curve is a plot of the corrected partition numbers,

HYDROCYCLONES By Richard A. Arterburn For many years, hydrocyclones, commonly referred to as cyclones, have,of the recovery curve near the 97% to 99% recovery level shows that the curve is nearly horizontal and a small differential

In many cases, the hydrocyclone partition curve exhibits a non-monotonic course in the fine particle range. The so-called fish-hook effect indicates an increased separation of the fine fraction, which is of practical interest and has a positive effect on solid/liquid separation. However, for classification purposes, the separation is less distinct.
