Working Principle. The Planetary Ball Mill has two or four ball grinding tanks installed on one turning plate. When the plate rotates, the tank axis makes planetary rotation in opposite direction and the grinding balls in the tanks grind and mix samples in high speed movement. The product can smash and blend various products of different materials and granularity with dry or wet methods.
Moreover, planetary ball mills are the most popular mills used in MA and MM processes for synthesizing almost all types of metastable and composite materials. In mills of this type, the milling media possess significantly high energy due to the movement of the milling stock and balls against the inner wall of the vial (milling bowl or jar).
The planetary ball mill is promising in that it makes grinding to submicron sizes possible by imparting high energy to the ground powder. In this context, there is a need to understand the dynamics of ultrafine grinding within the mill. ...
