More2018-12-9 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
