Ball consumption varies with the fineness of the product, hardness of the ore, quality of ball, and whether a mill is run in closed or open circuit. The ball, consumption for mills delivering a coarse product, all passing 8-mesh- and containing 10 to 20 per cent. below 200-mesh, the mill being run in open circuit, is about ½ lb. per ton for ...

"Coarsening" of ball mill is an abnormal phenomenon that the fineness of grinding products is significantly coarser and difficult to control. It generally occurs in double bin open circuit tube mill with small length diameter ratio. Coarsening of the ball mill will increase the energy consumption of the ball mill, cause waste, and large particle size will also affect the subsequent sorting.
