01 1.Increasing the grindability of raw ore. Commonly, the grindability is determined by the hardness, degree of dissociation, size and structure of raw ore. The small grindability means that the raw ore is easy to grind, which has relatively small wear on the liner and grinding media of the ball mill and low energy consumption.
