Attrition MillsPowder MetallurgyBeyond Discovery
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
