The primary ball charge pattern and the design ball charge pattern that is introduced by KHD Company (Cement ball mill's manufacture Company) are presented in Table 6. It can be observed in this table that the amount of current ball charge is about 14% less than the amount of design ball charge, so it could reduce the CBM's efficiency.
