    In tumbling mills, the charge motion and the power draw are largely a consequence of type and configuration of shell lifters for a given mill speed and filling In recent years, with increasing mill size whose power draw has reached over 20 MW, the use of large face angle shell lifter especially in combination with wider lifter spacing has beenTumbling mills have been widely implemented in many industrial sectors for the grinding of bulk materials They have been used for decades in the production of fines and in the final stages of ore comminution, where optimal levels for the enrichment particles’ sizes are obtained Even though these ubiquitous machines of relatively simple construction have been subjected to extensiveTumbling Mills | EncyclopediaFor conventional tumbling mills (rod, ball, and pebble mills), it has been found that models using a cumulative breakage rate function can easily be fitted to pilot or plant data and appear to be adequate for evaluating competing circuits (Hinde and King, 1978, Finch and RamirezCastro, 1980, Laplante et al, 1987) In these publicationsThe application of a simplified approach to modelling
