Hydrocyclone Separation Efficiency

Development of a hydrocyclone separation efficiency model ...

When classifying slurries, the separation efficiency (or the performance) of the hydrocyclone is described by the cut-size and the sharpness of classification coefficient, collectively referred to as a partition curve. These separation efficiency indicating parameters cannot be measured in real-time and are thus quantified by utilising models.
