Usage and limitations of hydrocyclone

What are the uses and limitations of Hydrocyclones? A hydrocycloneis most oftenused to separate "heavies" from a liquid mixture originating at acentrifugal pump or some other continuous source of pressurized liquid. Ahydrocyclone is most likely to be the right choice for processes where"lights" are the greater part of the mixture and where the ...

The Sizing Selection of Hydrocyclones

HYDROCYCLONES By Richard A. Arterburn For many years, hydrocyclones, commonly referred to as cyclones, have been extensively utilized in the classification of particles in comminution circuits. The practical range of classification for cyclones is 40 microns to 400 microns, with some remote applications as fine as 5 microns or as coarse as 1000 ...

How to resolve the most common hydrocyclone problems

Jul 23, 2020  In primary mill circuit base metal operations, hydrocyclones should be set up to produce underflow densities in the range of 50-55% by volume. Producing dilute cyclone underflow densities can lead to over grinding in the mill, translating to pay metal (product) recovery losses in flotation.
