Variables in Ball Mill Operation Paul O Abbe
The principle of mill operation is the impingement of the solids between pieces of media The majority of media motion and milling occurs on the surface of the bed of media where the media is cascading If there are too few solids then media will strike media with little milling effect but with accelerated wear of the media and mill shell.
