mills with the rod mill and ball mill laboratory work indices Note in Figure 1 that the rod mill product slope is less than 05 due to an extra amount of nes present being ner than 650 m These nes proceed to the ball mill improving the ball mill ef ciency Also the plotted rod mill P80 value as shown in Figure 1 is 2900
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
Ball mills are predominantly used machines for grinding in the cement industry Although ball mills have been used for more than one hundred years the design is still being improved in order to reduce the grinding costs HOLTEC has undertaken Performance Optimisation of
the effect of any ball mill design or operating variable Along with plant testing difficulties only fairly large changes in circuit performance could be linked to a media size Example calculation of test mill grinding rates Whether from a plant survey or torquemill test the calculation method of the mill
