The Mechanism and Grinding Limit of Planetary Ball

The surging phenomenon of the balls in the mill was confirmed by the photo­ graphic analysis. Based on this result, it is predicted that the grinding mechanism in the planetary ball mill consists of compressive, abrasive and shear stress of the balls, which is believed to be effective in producing very fine particles.
