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 Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
To calculate grinding media charge for continuous type ball mill, Calculations for mill ... Also, the spreadsheet allows for the calculation of the typical Grinding Media ... ball mills typically use the following form of the Bond equation:.
M = Grinding media charge in kgs D = Internal Dia of the Mill in cms. after lining L = Internal length of the mill in cms. after lining. To calculate grinding media charge for continuous type ball mill, M = 0.000676 x D2 x L Example - To calculate grinding media charge for a 180 cm dia x 180 cm long batch type ball mill with Duralox 50 mm thick ...

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
The Media Charge_Linear Wear_Ball Mills spreadsheet was designed to estimate the Linear Wear Rate Constants for a ball charge in a Conventional Ball Mill, as a function of its known dimensions and basic operating conditions. Also, the spreadsheet allows for the calculation of the typical Grinding Media Consumption Rate indicators; that is, gr ...
