01/05/2020 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. Also, it can be seen in

More### Mill Steel Charge Volume Calculation

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or ...
