Cyclones Resource Book. The P80 separation is the particle size for which 80% of the cyclone overflow is finer than that size. For example, if a sample of cyclone overflow was passed through a bank of screens and 80% of the sample was found to pass through (finer than) the 75µm screen then the P80 point for the overflow is 75µm.
