Most practical way to by measuring empty height and calculating the % volumetric filling of grinding media.Alternative way to make track of mill main drive kW consumption reduction and add makeup charge according to the extent of fall in power consumption.

Re: how to estimate the wear rate for Ball mill

Hey;

Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated. More simply and quite adequate is to keep a record of material ground and of charge added periodically to cover a given level of mill power. By this way you can measure easaly wear of ball/ ton of cement.

Piece weight also can be used for the wear rate of balls.And as make up charge in general 90 mm and 30 mm used.
