Closed Circuit Grinding VS Open Circuit Grinding

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.

Besides its impact on circuit capacity, high-frequency fine screening reduces the specific grinding energy of the circuit. In Table 2, specific grinding energies of the ball mill in closed circuit with cyclones and the ball mill in closed circuit with screens are calculated as 15.5 and 13.5 kWh/t, respectively. Therefore, the grinding energy is ...

crushed ore is fed into a SAG/Ball mill circuit with a median size of approximately 12,000 microns. Most SAG Mills are operated in closed circuit with a screen. The screen fi lters undersized ore, normally minus ½ inch, to a ball mill discharge sump. The combined mill discharg-es are pumped to undergo classifi cation, normally via hydrocyclones.

However, the application of screens in closed circuit with ball mills can increase the circuit capacity in the order of 20% due to the favourable effect of high classification efficiency. A ball mill circuit in closed circuit with screens can be designed using power-based methods, similarly to circuits closed with cyclones.
