Ball milling (BM), a micronization technology, has gained popularity for its high efficiency and simple operation in recent years (Yang et al., 2021). The main principle of BM is that when the cylinder rotates, the sample particles in the cylinder collide with each other repeatedly under the action of an external mechanical force, which is ...
