The tumbler ball mill contains a cylinder with milling balls in which an axial rotation causes these balls to roll down and impact against the powder (Fig. 2 b). In an attrition mill, a higher surface contact is ensured between balls and powder because of horizontal impellers and vertical rotating shaft ( Fig. 2 c).
