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

When ball milling, always use about 2/3 balls by volume. Make sure the drum isn't going too fast--say 2 revolutions per second, max. It helps to glue a couple of wooden "paddles" inside the drum to aid mixing. If the drum goes too fast, it will no longer tumble and drop the balls, but just throw things outward due to centrifugal force.
