    2016-9-14  Cut size is defined as (Svarovsky, 1984, p 23): Cut size d n is a diameter d for particles, which have a probability of n % to end up in un-derflow. So cut size d 90 is a particle size, which has a probability of 90 % to end up in underflow. A rough estimate for cut size is determined here from following condition with which the probabil-
