1.Principle The spindle driving the agitator do high-speed rotating, making the grinding medium to do irregular movement. The grinding medium would be collided, extruded, crushed and sheared because of the disorderly movement. Further, if the size, shape and ratio of the grinding media is different, the grinding effect would be also different . Under normal circumstances, the greater the specifications of the grinding medium, the more coarse the material; conversely, the smaller the grinding media, the finer the grinding materials. The abrasive effective would be better with appropriate ratio of different grinding medias specifications, coupled with the appropriate adjusting for speed. 2.
