Ball Charge and Grinding Efficiency - Grinding ...
The volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media …
Optimization of mill performance by using
For a better understanding of the decrease in the grinding efficiency, the media and pulp angles are recorded by the Sensomag®. From 69 to 73% of pulp solid content, the media angle keeps a constant value (184°) and the grinding zone fills up but remains unsaturated (media angle > pulp angle). From 74% the media angle exponentially increases with pulp
THE GRINDING CHARGE OF ROTARY MILLS - ugal.ro
between the wear of the grinding media and the wear of the lining parts is 4 – 10, especially in case of wet grinding where the specific, phenomena are more intense obviously, the wear of the grinding media depends of many factors, especially quality of the material and their thermal treatment, as well as the hardness and abrasive nature of
The operating principle of the ball mill
In a monolayer filling mill by grinding media, they rotate around their axis parallel to the drum axis of rotation. Grinding media are not subjected to a circular motion by a smooth lining, even at high speeds. In a multilayer filling mill by grinding media, depending on the rotational speed,...
Ball mill - Wikipedia
A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the balls, which may be made of steel (chrome steel), stainless steel, ceramic or rubber.
