    The method, however, works for ball mills as well. Relating to ball mills, the estimation of ball charge can be done even more exactly, because a great portion of the mass of the mill contents is made up of balls. In this case, from the power taken by the mill an estimate of the amount of balls can be obtained exceptionally well even directly.
