This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

Unlike the ball mill, however, the rod mill uses rods instead of balls as the grinding medium. as a result, its uses are different from those with the ball mill. in other words, the rod mill gives impact on and grinds coarse particles present between each rod, while no fine particles receive impact and are ground.
