high temperature screw grinding ball mill

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.
