Further tests were conducted in a mill with a 20% ball filling with increasing coarse or fine silica sand particle filling from 0 – 150% at the mill speeds of 63-98% of the critical mill speed. These tests clearly reveal radial segregation of coarse silica sand, increased ball cataracting and centrifuging of just silica sand or a combination of balls and silica sand. Get price
