Characteristics of open- and closed-circuit grinding systems

15/04/2004  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 the residence time in a continuous vibration ball ...

Grinding systems are either ‘open circuit’ or ‘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 ...
