For the ball mill efficient operation, it is necessary to constantly maintain the required loading level by the grinding media. It is very important to correctly and accurately measure the grinding media quantity in the mill. Measurements provided in the worked-out mill (without crushed material) by measuring the following parameters (measurements provided at three points – …
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.
