Nine Factors Affecting The Efficiency of Hydrocyclones
1. Cyclone diameter. The diameter of the hydrocyclone is an important condition that affects its working efficiency. The larger the diameter of the hydrocyclone, the larger the production capacity and separation particle size. 2. Cone angle. The working efficiency of the hydrocyclone decreases as the cone angle of the cyclone increases.

The dense medium cyclone – past, present and future
The dense medium separation process (DMS) is a mature technology, and is widely used in mineral and coal processing. The dense medium cyclone (DMC) is the most ubiquitous of the DMS vessels in use, and deservedly so. It is efficient (when run properly), can process both coarse and fine sizes, and has a relatively small footprint.

Hydrocyclone Feed Pump & Pressure PSI vs Operating Parameters
The problem now is to control the efficiency of the hydrocyclone.To do this you control the density of the cyclone. Because the cyclone works upon the pressure inside of it, adding or taking away water that is being fed to it will control the grind of the ore being discharged. As pressure increases inside the cyclone, the SPEED of the spiral …

A significant difference in recovery to underflow of intermediate-sized particles is found due to density effect. By increasing the feed d 0.5, the cut size, Ep value, solid concentration and yield of underflow present an increasing trend. Density effect coefficient is proposed and its extreme values are obtained for intermediate-sized particles.
