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.
Analysis ofarge amount of batch ball mill grinding data available in the literature has shown that the values of the power specific absolute rate of grinding of the topmost size fraction, and the power specific absolute rate of production of 100 mesh fines, are not independent of the mill operating conditions and mill diameter. in general, both the.
