  • What is Closed Circuit Crushing

    Reply Closed-circuit crushing is a means of controlling product top size by screening the product and then returning oversize material to the feed end of the crusher for another pass through the machine. While it may be possible to obtain a specified top size from crushers without using a closed-circuit system it is not always desirable.

  • Closed-circuit Clinker Grinding Mill Closed-circuit

    In an open circuit system the feeding rate of clinker is adjusted to achieve the desired granularity of the product at the mill exit. In a closed circuit system coarse particles are separated from the finer product and returned for a further grinding. In a closed circuit mill the total throughput is higher and hence the size of material from
