Abstract： To study the motion principles of grinding media in the vial of horizontal planetary ball mill, the relative motion equation was established to theoretically solve the detaching condition, trajectory and time. The results show that the grinding media in horizontal planetary ball mill and in traditional ball mill are completely motion similarity and dynamic similarity. When the planetary factor is z, the geometry sizes of planetary ball mill are z1/4 times as those of traditional ball mill. The energy saving rate of planetary ball mill to traditional ball mill is proved to be (1.29z3/8-1) /(1.29z3/8) by the principle of similarity.
Keywords: ball mill; planetary ball mill; motion similarity; dynamic similarity; energy-saving
