1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill in addition to the nature of the material grain sie hardness density temperature and humidity the degree of
