The grinding effect and efficiency of planetary ball mill on materials are affected by many factors, such as rotation speed, charging volume, grinding balls, ball mill tank, grinding time, etc. Among these factors, the speed of planetary ball mill has a great influence on its efficiency and effect.

The planetary ball mill machine mainly uses the centrifugal force and friction force of the grinding balls and materials in the ball mill tank to crush and mix the materials. In planetary operation, the grinding ball is subjected to the centrifugal force of the rotation of the main planetary disk, the centrifugal force and frictional force of the rotation of the ball mill tank. Under the action of these three forces, the grinding ball will leave the wall of the ball mill tank and hit the material on the other side.

When other conditions are the same, in the process of grinding balls impacting the material, the impact angle will change accordingly as the rotation speed increases or decreases, and the impact effect will be 90° vertically. This is naturally the ultimate goal of adjusting the rotation speed, so as to control the impact trajectory of most grinding balls in the most ideal state.

Therefore, when choosing lab planetary ball mill, the higher the speed parameter, it does not mean it is the better. The speed of planetary ball mills currently on the market all can meet the requirements. More attention to the quality, stability and control method of planetary ball mills is the key to choosing a planetary ball mill.
