The mass of grinding balls will change with the size. 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.

The size and rotation speed of planetary ball mill: the larger the planetary ball mill is, the larger the diameter of the ball mill tank is, the corresponding increase in the movement speed of the grinding ball, the greater the impact, and the accelerated wear. It's the same thing when speed is too fast.

Types and properties of grinding balls: different grinding balls have different wear conditions with different density, hardness, elasticity, wear resistance and acid-base resistance.
