Cast grinding balls in the ball mill play a very important role in the grinding process. If they are not used properly, various operational problems are very likely to occur.

In actual production, there are generally two scenarios. In one case, the hardness of the casting grinding ball is lower than that of the ore by more than 3 points on the Rockwell hardness scale. During the grinding process of the minerals, the casting grinding ball wear out at a faster rate and the consumption increases. Another situation is that when the hardness of the ore is high, and the hardness of the casting grinding ball is 3 R values higher than that of the ore, during the grinding process of the ore, the casting grinding balls and the ore will undergo sliding wear, which weakens the erosion and grinding effect, resulting in an increase in useless work, a decrease in the processing capacity of the ore, a higher grinding temperature, and an increase in the consumption of the casting grinding balls.
