### Mill Steel Charge Volume Calculation

Jun 19 2015 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 Loading Dry Milling Paul O Abbe

50 media charge; Assuming 26 void space between spherical balls non-spherical irregularly shaped and mixed-size media will increase or decrease the free space 50 x 26 13 free space; 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.

For overflow ball mills the charge should not exceed 45 of the mill volume. For grate discharge mills the charge should occupy about 50 of the mill volume. Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge He and the radius of the mill R i.e.
