    Even in a Mixer Mill, which generally uses less grinding media and therefore creates less friction than a planetary mill, temperatures exceeding 100 ºC are not unusual. When using spherical media in a ball mill, the only way to reduce friction is to reduce the number of pieces of media however, this in turn reduces the efficiency of grinding.
