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.

     · Ball Mills are generally used to grind material 1/4 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers such as screens spiral
