Total grinding ball charge. The amount of mill charges reflects the proportion of the working volume of the mill to the bulk volume of the grinding media. The ball charge can vary between 25 and 45 %. Balls that are charged below 25 % slide along the mill liner; those that are charged above 45 % interrupt the motion of the grinding media.
