efficiency of hydrocyclones cyclones using relative densities

Hydrocyclone Wiki Everipedia

Hydrocyclone''s wiki: A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

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 overflow until the drop
