    Oct 31, 2019 In the grinding operation, the consumption of steel ball is very large, which is about 10 times more than the loss of ball mill liner. In order to make up for the loss of steel ball and keep the size of the steel ball unchanged in the ball mill machine, it is necessary to add the steel ball regularly according to a certain ratio.
