you cannot use work index analysis for the same purpose on ball mill circuits because of the complex interactions between grinding and classification. In this module, you will learn how to relate design and operating variables to ball mill circuit efficiency through functional performance analysis*. This Introduction is seven pages long.

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 …
