The dual-planet structure enables the large planetary disk to drive the movement of the small planetary disk, amplifying the orbital radius and the rotation speed of the grinding jar compared to ordinary planetary ball mills of the same specifications. The centrifugal force acting on the grinding balls increases exponentially, significantly enhancing the collision, shear, and friction forces between the balls, thereby improving grinding effectiveness and efficiency. Some materials can be ground to the nanoscale. The dual-planet ball mill is a typical high-efficiency, high-energy ball mill.
