The Reason Why The Amount Of Grinding Media Balls Is Only Added By 80% During The Running-in Process

Why only 80% of the ball mill steel balls are added during the running-in process of the ball mill, because after the ball mill is installed, the large and small gears of the ball mill need to mesh, and the processing capacity should gradually increase. After the ball mill runs normally for two or three days, check the meshing of the large and small gears , when everything is normal, open the manhole cover of the ball mill and add the remaining 20% steel balls for the second time.

Note: The addition of small steel balls is only used for the first time. Because the reasonable friction between the steel ball and the steel ball, the steel ball and the ore, and the steel ball and the ball mill liner during the normal operation of the ball mill will increase the wear and tear, making the large ball mill small and the medium ball mill into small balls. Therefore, under normal circumstances, there is no need to add a small ball. In the case of adding small balls, there is no monomer dissociation in the particle size of useful minerals. When the fineness of the mill does not meet the flotation requirements, an appropriate amount of small balls can be added. The steel balls in the ball mill are constantly worn out during the operation. In order to maintain a reasonable ratio of ball charge filling rate and balls, and maintain the stable operation of the ball mill, it is necessary to carry out reasonable supplementary balls and low compensation wear.

The added weight of the steel balls depends on the quality of the steel balls. The quality of the steel balls determines the added amount of ore per ton consumption. It is best to use new wear-resistant steel balls, such as steel forged by special treatment of train wheels. The ball is very durable.
