Discrete Element Method Simulation of Filling Level in Planetary Ball Mill

In this study, DEM (discrete element method) was used to improve our understanding of the fundamental processes involved in the ball milling process, with a particular emphasis on the effect of the many different filling levels in planetary ball mills. This DEM methodology facilitates the simulation of the behavior of balls and powder particles inside the vials, enabling an understanding of the nature of the material milling and the structure of the flow. The major benefit of the DEM technique is the ability to incorporate interrelationships among different milling parameters. The simulations indicate that changing the filling level has a significant effect on the ball milling process.
