High Energy Ball Mill
The Mini Planetary Ball Mill features four ball grinding tanks mounted on a single turntable. As the turntable rotates, the tanks revolve around their own axes, resulting in planetary movements. The high-speed movement of the balls and samples within the tanks leads to strong impact forces that eventually grind the samples into powder.
