"A study of ball mills" by Robert Lee Kidd - Scholars'

"The study of the ball mill is very complicated, due to the varying conditions existing in the mill. Some of these conditions are: Size of grinding media, size of feed, moisture content, and speed with its effect on the paths of the grinding media. A brief history of fine grinding will first be outlines, after which some of the theories of ball milling will be stated.
