In a planetary ball mill, the grinding jars rotate on their own axis while simultaneously revolving around a central axis. This dual movement creates a high-energy environment inside the jars. The mechanism involves the use of grinding balls of various sizes, which collide with the material being milled. This collision generates the energy needed to break down the material into nanostructures. The process can be fine-tuned by adjusting parameters such as the speed of rotation, the size and material of the grinding balls, and the duration of milling.
