Feb 13, 2017 In present-day practice, the ore is reduced to a size many times finer than can be obtained with crushers. Over a period of many years, various fine grinding mills have been developed and used, but the ball mill has become standard due to its simplicity and low operating cost. A ball mill efficiently operated performs a wide variety of services
