"A study of ball mills" by Robert Lee Kidd
"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.

How to choose the material of ball mill jar
Generally speaking, the selection of ball milling jar is mainly considered from hardness, corrosion resistance, pollution and vacuum grinding. First of all, the hardness of the sample needs to be smaller than that of the ball mill and the grinding ball. Otherwise, the sample will wear the ball mill jar and the grinding ball during the ball mill ...
