Abstract The residency time of grinding balls inside grinding mills has been calculated in the present work assuming an abrasive wear mechanism without breakage. From the ratio of total weight of balls in the mill to the daily addition weight of balls, the ratio of the grate openings size of the mill to the original ball size, and the rotation rate of the mill, the residency time of grinding ...

2019-8-30 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 size, hardness, density, temperature and humidity), the degree of
