University of Liège

mill depends not only on the operating conditions, i.e. mainly the rotation speed and the ﬁlling ratio, but also on the liner itself. For this reason, the slightest improvement of the liner design becomes a signiﬁcant competitive advantage. In general, the liner design depends on its material and its initial shape. Due to the collisions
