Ball Mill - an overview | ScienceDirect Topics

The rate of milling decreases as the size of the powder decreases due to aggregation of particles (tendency of small particles to stick together – this is why wet milling can be used to get smaller particles) and the fact that smaller particles tend to be stronger than bigger ones, meaning that fewer fracture when hit by the media A variant of the rotating (or tumbling) ball mill is the
