2004-4-15 Abstract. 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.

Contact2016-10-12 Open Circuit Grinding. Open circuit grinding consists of one or more grinding mills, either parallel or in series, that discharges a final ground product

Contact2020-1-15 The open-circuit grinding is suitable for the first grinding. The material discharged from one section of the rod mill enters other grinding equipment and is then ground (fine). In this way, the first section of the rod mill has a smaller crushing ratio and higher production capacity, and the process is relatively simple.
