A typical circuit of this type is shown below. As grinding becomes finer Ball Mills are required and closed circuit operation is generally recommended. Air separators do the sizing work as shown in a typical circuit. In dry grinding work, principally fine grinding, size reduction is accomplished predominantly by attrition rather than impact.
Its coverage area is reduced by 50% compared with ball mill, and the energy consumption is saved by 30%-40% similarly. This mill itself can crush, dry, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so it will reduce a large number of investment costs.
