THE MODE OF BALL MILL OPERATION - energosteel

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.
