Hydrocyclone Selection
The best-known hydrocyclone design model is Arterburn's model, also known as the Krebs model. Arterburn [] developed an empirical model that estimates the size and number of hydrocyclones required for a given comminution-classification operation.The method was developed for the normalized and standardized geometry of …

6 Factors That Affect Hydrocyclone Performance
A low feed pressure results in a coarser cut, while a high feed pressure results in a finer separation. Pressure can be decreased by decreasing the flow rate, or it can be increased by increasing the flow rate. When optimizing the performance of Hydrocyclone, be it a coarser cut or finer cut, look to the Pump that's feeding the …

Hydrocyclone Design
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 …

The control strategy could be to monitor the deviation of the cut point. The alteration in cut point was obviously due to change in feed characteristics and additionally to changes in cyclone geometry due to abrasion.

1. Pressure at the inlet of the Hydrocyclone can tell you a lot. Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be. The separation point is the size at which a particle has a 50-50 chance of reporting either to the underflow or overflow.

Hydrocyclone Cut Point
The cut point of a hydrocyclone is the size of a particle, below which most of the particles will be separated from the feed material. The cut point is usually expressed as a specific size, or a range of sizes, such as 40 to 60 microns.

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 …

Hydrocyclone Separator
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.

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.
