that to get a cyclone overflow with minus say, 200 microns we must cut much finer than this. It has been agreed that the best way to describe a cyclone's cut point is the d50. This is the size of particle which has a 50:50 probability of reporting to either the underflow or overflow. Please note that the d50 cutpoint only describes the ...

cut-size and sharpness of classification coefficient, are related to it. The cut-size, indicated as @ 9 4, is defined as the size of the particle in the Particle Size Distribution (PSD) that has a 50% probability of reporting to either the underflow or the overflow of the hydrocyclone (Bradley, 1965).

For example, an important part of control of hydrocyclones is stabilization of the slurry density in the overflow or cut point for feeds with varying solids concentrations and particle size distributions (Neesse et al., 2004b, Hodouin, 2011). Regulation of the volume split has been restricted to single large cyclones fitted with adjustable nozzles.

Particles finer than the "cut point" size migrate into a secondary upward-moving vortex, along the axis of the hydrocyclone and discharge with the majority of the water. Hydrocyclones are limited in being able to dewater fine solids to a conveyable state Dewatering Screens are used to further dewater Hydrocyclone underflow.

It is common to call "design" the election of the sizes of the parts of hydrocyclones chosen from those provided by the manufacturers. It is really a geometric selection for which empirical formulas exist (see Chap. 9).In this chapter we will develop a design for hydrocyclones as a mixed-flow turbo machine including different inlet, vortex …

8.1.3 Pressure–volume Flow in a Hydrocyclone as a Turbo Machine Figure 8.5 shows a hydrocyclone with an involute inlet as the inverse of a turbo machine; that is, the inlet of the former is the outlet of the latter. A hydrocyclone does not generate power; therefore, Eq. (8.2) leads to ρQ(vθ2 r 2 −vθr) = 0 vθ = vθ2 r 2 r (8.5)
