The experiments also show that the useful power of the centrifugalmill is account for 40% of the input power, and it is higher than the ordinary ball mill (which account for 30%).
试验还得知，离心磨矿机的有用功率为输入功率的4 0 %左右，高于普通球磨机(30 %)。

The movement law of the grinding balls in planetary ballmill is mainly determined by centrifugal force.
