Why do planetary ball mills use grinding balls of different sizes? Today, Chi Shun Technology will summarize for everyone:

The grinding ball plays a crucial role in the grinding process of planetary ball mills. The ball mill operates with animal feed and grinding balls, and the energy of the grinding balls continuously acts on the materials, thereby crushing or mixing them to an ideal state; Many planetary ball mill users always have various sizes of grinding balls when receiving grinding balls from planetary ball mill manufacturers. Why do planetary ball mills use different sizes of grinding balls? The grinding effect and efficiency of balls of different sizes are better than those of single sizes.

Using only small balls clearly results in low energy and efficiency.

Using only a large ball, although it has high energy, it has fewer interactions with the same mass at the same time. Moreover, according to Davis' grinding ball wear hypothesis, the wear speed of the ball is proportional to its mass.

The planetary ball mill uses grinding balls of different sizes. The high energy of the large balls has a strong effect on the large materials, and the small balls are filled in the gaps between the large balls, which correspond to the different thicknesses of materials and improve the grinding efficiency. The two complement each other in order to improve the efficiency and effectiveness of the planetary grinding machine!
