THE MODE OF BALL MILL OPERATION -

2020-9-10  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.

The operating principle of the ball mill -

2017-2-8  The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
