Particle size distributions of the feed, underflow and overflow streams. d 95 (overflow) = 95 microns. d 95 (underflow & feed) = 750; Due to inefficiencies, every particle in the feed has a probability of reporting to either the underflow or overflow streams. The particle size having a 50% chance of reporting to either stream is the d50. Plitt ...
