The charge volume of a ball or rod mill is expressed as the percentage of the volume within the liners filled with balls or rods. When the mill is stationary, the charge volume can be quickly obtained by measuring the diameter inside the liners and the distance from the top of the mill inside the liners to the top of the charge. The percentage.

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.Rod mills accept feed up to about 50 mm 2 in. and produce a product in the size range of.
