    Sep 10, 2020  The mill operation modes are as follows: The ”cascade” – the rolling the grinding balls inside the mill drum. Mixed mode – the rolling the grinding balls when part of the grinding balls move in a circular trajectory with further fall. Waterfall – the grinding balls move along a circular trajectory and change it further under gravity.
