    Although large balls have large energy, they have fewer actions at the same time with the same mass. Moreover, according to Davis' hypothesis of grinding ball wear, the wear rate of the ball is proportional to the mass. The planetary ball mill adopts grinding balls of different sizes. The high energy of the large ball has a strong effect on the
