Dec 04, 2019(1) If it is too much, the grinding media will be overlapped with each other, thus the crushing capacity of each steel ball cannot be fully utilized and the kinetic energy consumption will be increased. (2) If it is too little, although the crushing capacity of each steel ball is fully exerted, the total crushing capacity is still limited.
