The grinding effect and efficiency of a planetary ball mill are affected by many factors, such as speed, loading capacity, grinding balls, grinding jars, grinding time, etc. Among them, the speed of a planetary ball mill has a greater impact on its efficiency and effect. So how should we choose the speed parameter when purchasing a planetary ball mill?

Lab planetary ball mill mainly crushes and mixes materials by the centrifugal force and friction force of the grinding balls and materials in the ball mill. In the planetary operation, the grinding balls are subjected to the centrifugal force of the planetary main plate, the centrifugal force and friction force of the ball mill rotation. Under the action of these three forces, the grinding balls will leave the wall of the ball mill and hit the materials on the other side.

Under the same conditions, when the grinding balls hit the materials, as the speed increases or decreases, the impact angle will change accordingly, and the impact effect will be 90° vertical. This is the ultimate purpose of adjusting the speed, to control the impact trajectory of most grinding balls in the most ideal state.

When choosing a compact planetary ball mill, the speed parameter is not the higher the better. Planetary ball mill manufacturers have already taken these factors into consideration when designing. Paying more attention to the quality, stability, and control method is the key to choosing a planetary ball mill.
