charge lifting rate, and thus they affect mill performance. It was found that the different ratios of spacing-to-height of lifter bars in an autogenous mill significantly affect the specific power and mill capacity. Therefore, using the spacing-to-height (S/H) ratio of 4-4.5 could give the optimum specific power and capacity [6].
