Abstract：To understand the influence of many variables related to system geometry, operating conditions and material properties on the performance of planetary ball mill, the researches both at home and abroad about the simulation and analysis of the milling process of planetary ball mill using discrete element method were analyzed and summarized. The progress was reviewed from the aspects of charge motion, energy conversion, wear and scale-up. The results show that optimization of operating conditions can make effective collisions and high energy collisions be in the optimum ratios. The effect of impact and grinding for the refinement of materials remains to be explored under specific environment. The agglomeration and lubrication of powders can hinder powder refinement. When the planetary mill is scaled-up in geometrical similarity, the impact energy of balls is propotional to 4.87 power of the scale-up ratio.
