#### 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 millBall Charge and Grinding Efficiency Grinding,Also with low ball charge slurry pool will reduce grinding efficiency. Beside lower ball charge will increase P80 of ball mill because of less number of impacts but mean residence time will increase by lower ball charge because of more volume to occupy. I think at

#### Ball Mill Charge Grinding & Classification Circuits

The ball charge and ore charge volume is a variable, subject to what is the target for that operation.
