Abstract: The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ball-milling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ball-milling process. Furthermore, by comparing the information with the experimental data for a ball mill, the motion trajectory of the grinding ball, and the energy transfer between the balls and materials were studied, and the micro process during milling was discussed. This study provides a certain theoretical basis for the follow-up engineering application.
