  • Characteristics of open- and closed-circuit grinding

    Apr 15, 2004· A closed-circuit grinding system, using a continuous vibration ball mill has been applied to the production of fine particles. However in most cases, the operational conditions are determined empirically. The reason for using empirical operational conditions is that it is difficult to estimate grinding performance. The grinding rate constant or

  • What are the advantages of open circuit system and closed

    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
