Attrition Mills - Powder Metallurgy - Beyond Discovery
2022-1-7 · 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.. Fig. 24 Attrition ball mill
