Study on the impacts of media shapes on the performance
Highlights. •. Shape of grinding media can affect the performance of a tumbling mill. •. Balls have the higher lifter/media ratio than the other media. •. Compared to worn and spherical media, the power draw for cylpebs reached its maximum at a lower speed. •. The highest and lowest degree for shoulder position occurred when cylpebs and ...

Abstract The effect of grinding media on milling kinetics has been generally studied using one media shape. However, very little work has been done on investigating mixtures of media shapes. Combining different grinding mechanisms in term of contacts, the volume of grinding zones can be efficiently increased when there is an optimal mixture of two or more grinding media with different shapes ...
