Ball mill is widely used in cement, electric power, mineral processing, building materials, and other industries. As the grinding medium in the ball mill, the grinding ball must have both high wear resistance and good toughness. In recent years, with the rapid development of China's industry, the consumption of grinding ball is very large.
Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between media shape and mill power.
Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include: Speed of mill rotation; Mill diameter; Mineral density;
