In order to investigate the breakage behavior of the feed in industrial secondary ball mills, the breakage characteristics of fine magnetite were analyzed. Magnetite particle breakage produces a bimodal particle size distribution that is consistent with the typical breakage characteristics of abrasion. The secondary ball mill can increase the surface area by reducing the diameter of steel ...

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.
