The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.

The advantage of closed circuit system is eliminating over grinding phenomenon and reducing temperature of grinding chamber. Then the grinding efficiency and capacity is improved. In general, the capacity can be improved by 10%-20% compared with cement mill when these specifications are similar. And capacity can be improved by 30% when grinding ...
