Hydrocyclone - Wikipedia

Hydrocyclones are of cyclonic separators that separating product phases mainly on basis of differences in gravity with aqueous solutions as the primary feed fluid. As opposed to dry or dust cyclones, which separate solids from gasses, hydrocyclones separate solids or different phase fluids from the bulk fluid. A hydrocyclone comprises a ...

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.
