The dry grinding of alumina was performed in a planetary ball mill PM400 (Retsch ) with a sun wheel radius R SUN of 150 mm and a gear ratio of k = −2. The gear ratio is defined as relative rotational speed of grinding chamber n GC in relation to the rotational speed of the sun disc n SUN: (2) k = n GC n SUN = - 2.
