Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.

Reason #2：The supplement of steel balls is insufficient. Due to the longterm 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.
