the diameter. Likewise the size of a cube can be defined unambiguously as the length of a side but another dimension could be equally well used such as the longest diagonal. Particle size clearly does not have a unique meaning even for particles with regular shapes. In mineral processing technology an indirect measure of size is used. The size of a Get price

[PDF] THE SIZING AND SELECTION OF HYDROCYCLONES By

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 Get price

Screening Theory and Practice
