Hydrocyclones - an overview ScienceDirect Topics

12.6.1 Efficiency of separation in hydrocyclones. By convention the efficiency of operation and separation of hydrocyclones are determined by the sharpness of separation and the d 50 value. Less conventional but also widely used is the d 95 cut point which is the size at which 95% of the particles have the probability of reporting to the underflow.
