How to Choose Open-circuit Grinding or Closed

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.
