hydrocyclone is found to be a viable alternative for efficient solid–liquid separation. In mineral industry, hydrocyclone has found wide application as a classifier [4]. The tangential entry of particles at a high pressure in form of slurry into hydrocyclone attains a swirling motion. This results in radial distribution of particles

Hydrocyclone Design | SpringerLink

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 and apex …

Chapter 8 Hydrocyclone Design

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)

Hydrocyclone Separator | Multotec

In a hydrocyclone, cut size is the separation point between particles deemed to be either 'coarse' or 'fine'. If a particle is at the cut point size, it will have a 50% chance of reporting to either the overflow or underflow. Any particle size greater than the cut size is deemed a coarse particle and will exit via the underflow.

Operations. Figure 18 shows the regular operation of hydrocyclone equipment for solid control. The hydrocyclone cut point is the particle size at which 50% of the particles of that size will be discarded (Figure 20). A typical cut point for a desilter is 20 microns, and a desander is 40 microns.

Hydrocyclones

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.

How to use a hydrocyclone: 5 things you need to know

Although it is not much evidence, the installed angle of the Hydrocyclone can also change the cut point. If multiple, smaller Hydrocyclones are operating simultaneously at the same pressure, then one large Hydrocyclone will have a finer cut point. The two forces have a major impact on the cut points of the Hydrocyclone, that is, centrifugal and ...

HYDROCYCLONE

The cut point is related to the inside diameter of the hydrocyclone. For example, a 12-inch cone is capable of a D50 cut point of around 60 to 80 microns; a 6-inch cone is capable of around 40 to 60 microns; and a 4-inch cone is capable of around 20 to 40 microns. These cut points are representative for a fluid that contains a low solids ...
