that to get a cyclone overflow with minus say, 200 microns we must cut much finer than this. It has been agreed that the best way to describe a cyclone's cut point is the d50. This is the size of particle which has a 50:50 probability of reporting to either the underflow or overflow. Please note that the d50 cutpoint only describes the ...
