Attrition Mills - Powder Metallurgy - Beyond Discovery

2020-12-13  Milling in an attrition mill(Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills.
