Note that the models proposed earlier for mechanical alloying in planetary mill [23], [24] ignored rolling ball motion as affecting the refinement or phase changes in the powder being processed. In those models, the refinement was considered as a function of the overall energy transfer from the balls to powder as a result of ball collisions ...

The planetary ball mill is equipped with four ball mill pots on the same turntable. When the turntable rotates, the ball mill pan revolves around the turntable axis and at the same time rotates around its own axis, making planetary motions. The grinding balls in the tank collide with each other in highspeed motion to grind and mix the sample.

The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling 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 ballmilling process. Furthermore, by ...
