Power draw estimations in experimental tumbling mills
1. Introduction. The power draw of a tumbling mill is known to be an important measure in determining its efficiency. Many models have been derived to predict the power draw as a function of characteristics related to charge motion (Harris and Schnock 1985 Morell 1992).While these models have been shown to calculate good approximations of mill power they have been observed to be limited to
