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.
slice mills are identical to the ball mills and ceramic lined mills in diameter and design the only difference is that they are as little as in length. since mill diameter dictates performance and mill length only affects capacity, slice mills are used to develop or
the mill is used primarily to lift the load additional power is required to keep the mill rotating. 8.1.3 power drawn by ball, semi-autogenous and autogenous mills simplified picture of the mill load is shown in figure 8.3 Ad this can be used to establish the essential features of a model for mill
