The law of ball size distribution in the horizontal planetary ball mill is studied by the discrete element method. The results show that the maximum impact energy could be acquired when filling rate is 24%, moreover the biggest mean contact force and the highest energy utilization ratio of balls could be acquired when the speed ratio is

This present work focuses on DEM simulations of a scale laboratory planetary ball mill through DEM Altair software to optimize and modulate the milling parameters. The simulation results show a good agreement with the experiments. The numerical model is shown to be a promising tool for the knowledge of dry milling in a planetary ball mill.

The aim of this study is to evaluate the effect that the size of grinding media exerts on ferronickel slag milling efficiency and energy savings. A series of tests were performed in a laboratory ball mill using (i) three loads of single size media,, 40,, and mm and (ii) a mixed load of balls with varying sizes. In order to simulate the industrial ball milling operation, the feed ...

in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle. Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (, a 34ftdiameter mill shell would have 68 shell lifters).
