به خواندن ادامه دهیدReason #2:The supplement of steel balls is insufficient. Due to the long-term operation of ball mill, the steel balls will wear violently, the diameter will be reduced, and the impact force will be correspondingly weakened. When the steel balls in the ball mill are not replenished in time, the processing capacity of the ball mill will be reduced.
