The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill or large lumps of ore in an autogenous mill or a mixture in a semi-autogenous mill as well as the slurry that makes up the operating charge. Let Jt be the fraction of the mill volume that is occupied 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. The loading or change volume can then be read off the graph below or
