and ball mills, have almost become obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous (AG) or semi-autogenous (SAG) mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades.A discussion on the measurement of grinding media wear ,A discussion on the measurement of grinding media wear. One of the major problems regarding the use of ball mills is to balance the size distribution of grinding media into the mill, which is determined by the speed of consumption and rate of replacement,
