The higher breakage rates in the RoM ball mill are an indication that the higher ball loads in these mills enhance breakage.Higher breakage rates at the coarser sizes result in higher throughputs and higher breakage rates at the finer sizes in finer grind. Allocation of costs for the lining, power, and grinding media for a RoM ball mill is higher.
Cement Ball Mill Structure. When Ball Mill is working, raw material enters the mill cylinder through the hollow shaft of the feed.
