You can make it coarser (more material out the overflow) or finer (more material out the underflow). To make a hydrocyclone cut finer, here are some of the options generally available: Increase feed pressure/flow. The higher the feed pressure to the hydrocyclone, the finer the cut it will make, and the more solids will report to the underflow.

How to Improve Cyclone Separation

Good cyclone separation depends upon control of pressure drop, pulp density and apex size. The 'pressure drop' may vary but should not change rapidly, and is held at safe levels by keeping an adequate sump level. A falling sump level causes cavitation in the pump and reduction in feed rate; pressure drop in the cyclone falls and solids report increasingly to the …

Under the action of pressure, the ore slurry enters the shell along the tangent direction of the pillar body. And rotates in the hydrocyclone shell. The coarse particles (or the dense particles) enter the periphery of rotary current due to them get the larger centrifugal force. At the same time, the coarse particles downward flow with ore slurry.

Hydrocyclone in Operation Cyclone in Operation. The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the "OVERFLOW" via a Vortex Finder. The mineral that still requires grinding is named the "UNDERFLOW" via the Apex Finder.
