• 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 approximated from the equation and calculation Steel Charge Loading in Mill 113 126 H D Ball Mill Charge Volume Calculation Charge Volume of a Grinding Mill Method 1 Charge Volume of a Grinding Mill

Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading. So as a rule of thumb we use 25% solid loading. Empirical Check: Once the mill has been loaded and run for a few minutes, open the cover and look down into the mill. You should see some discernible layer of product on top of the media.
