The ball mill working process is carried out in the cylinder. After the ball mill grinding media in the cylinder body is brought to a certain height with the rotation of the cylinder body, the ball mill grinding media falls due to its self-weight, and the raw materials in the cylinder body are severely impacted by the grinding media.

Commercial discrete element computing software was applied to simulate the HTBM process at different parameters. To reduce computation time, the model of the ball mill tank was scaled down, and the powder and ball milling media model remained unchanged, as shown in Fig. 3 (a), which is the same approach used by Jiang et al. [31], [32], [33].

the milling process takes place during rotation as a result of the transfer of kinetic energy of the moving grinding media into the grinding product. The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product.
