A ball mill is a drumgrinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. then the grinding media are again below.
The sample is added along with the grinding balls in a grinding bowl in a planetary ball mill. the grinding bowls are fastened to a so called sun disk and turn counter clockwise around the centre of the disk. due to impact, blow and friction effects.
