### Mill Steel Charge Volume Calculation

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.

### Ball Mill Charge - Grinding & Classification Circuits ...

2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge. This energy is required to cause grinding of the material in the mill.
