The planetary ball mill is equipped with four ball mill pots on the same turntable. When the turntable rotates, the ball mill pan revolves around the turntable axis and at the same time rotates around its own axis, making planetary motions. The grinding balls in the tank collide with each other in highspeed motion to grind and mix the sample.
