Improving cyclone efficiency for small particles

2019-7-1 · Cyclone efficiencies are measured frequently by a ''cut point'', meaning that the collection efficiency (or grade) is 50%. For larger particles the collection efficiency approaches . For many cyclones used in industry, the cut point is less than 5 microns, normalized for shape and density, Koch and Licht (1977).
