At a certain speed of planetary ball mill, the larger the mass of grinding ball is, the greater the impact will be. When configuring the grinding balls, the probability of collision between the same size grinding balls is higher, and the grinding balls are prone to fatigue wear. The load of grinding balls will also affect the probability of collision between the grinding balls.
