While themillis stopped, thechargevolume can be gotten by measuring the diameter inside the liners and the distance from the top of thechargeto the top of themill. The % loading or change volume can then be read off the graph below or approximated from the equation andcalculation: %Steel Charge LoadinginMill= 113 – 126 H/ D

Ball Mill Charge - Grinding & Classification Circuits
Theball chargeand ore charge volume is a variable, subject to what is the target for that operation. The type ofmillalso is a factor as if it is an overflowmill(subject to the diameter of the discharge port) is usually up to about 40-45%. If it is a grate discharge you will have more flexibility of the totalcharge.
