Ball Mill Application and Design Paul O. Abbe

Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 1.5”. The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.

MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions: • The grinding of coarse particles; and, • The removal of the fine particles to make room for grind-ing more coarse particles in the ball mill. The overall efficiency of the ball mill circuit is therefore comprised of
