Grinding systems are either ''open circuit'' or ''closed circuit.'' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.

Cement mill notebook SlideShare. Jan 07, 2015 Figure: Open circuit mill 2. Closed Circuit: A closed circuit is the system in which the material at the outlet of the mill passes through a separator, driving the material with the required fineness to the storage silo and the coarse particles back to the mill inlet.

Closed circuit grinding system. See the advantages of closed circuit grinding. The method of installing a bowl classifier to overcome the difficulty is shown in Fig. 27. This circuit is usually adopted in modern practice, but with a bowl instead of a straight classifier, if necessary, in the closed circuit of the secondary ball mill.

Wustner reported that 30% reduction in energy use was achieved after the conversion of closed circuit ball mill to a semi-finish grinding circuit with a HPGR. Applications of HPGR in different circuit alternatives have resulted in 10–50% energy savings compared to closed circuit ball milling operations [66] .
