why classifiers are used in ball mill

Ball Mills - Mt Baker Mining and Metals. Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to 200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.
