2018-5-29 Improving the classification efficiency of individual hydrocyclones will improve the overall classification efficiency of a hydrocyclone cluster. This leads to less variation in the particle size distribution and slurry density in the flotation feed, which will in turn improve overall mineral recovery. ...

In nanotechnology, classification in the micron and submicron range is of growing interest. Usually, hydrocyclones do not reach these low cut sizes. This study presents a special batch processing technique using a 20 mm hydrocyclone for classification in the micron range. This hydrocyclone was equipped with a special underflow box that stored the coarse particles.

The application of hydrocyclones as separation devices is exceedingly diverse, and one of the recent trends is the development of hydrocyclones for the classification of fine particles. However, classification inefficiencies, such as their large bypass, represent a major hurdle that will have to be surmounted before they could be competitive with other devices in this regard.

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 microns. Cyclones are used in both primary and secondary grinding circuits as well as ...
