PLANETARY BALL MILL AND A MILLING METHOD

摘要

The energy for milling materials is mainly adopted from the ball mill's inertia instead of ball's gravity. In convention ball mill, the position of the separation point between ball and wall of the ball mill depends on the rotation speed. In the invented planetary ball mill, the position of the separation point has no dependence of the rotation speed. It is this reason that the impacting frequency and intensity can be increased. The invention introduced a unique and efficient method for mechanical alloying of multi-component materials and preparing of nano-sized powder.
