While themillis 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

The starting point for ball mill media and solids charging generally starts as follows: 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.
In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 RodMill Charge. Rodmillcharges usually occupy about 45% of the internalvolumeof themill. A closely packedchargeof single sized rods will have a porosity of 9.3%. With a mixedchargeof small and large diameter rods, the porosity of a static load could be reduced even further.
The maximum power draw in ball mill is when ball bed is 35-40 % by volume in whole empty mill volume. Considering that ball bed has a porosity of 40 %, the actual ball …
