The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.

Open Circuit Closed Circuit; Path: The path in an open circuit is closed and has no continuity. The path in a closed circuit is open and has complete continuity: Flow: In an open circuit, the current does not flow due to an interrupted path. In a closed circuit, the current flows perfectly because the path is not broken anywhere. On/Off

The significant distinction between an open circuit and a closed circuit is that in a closed circuit, there is no damaged pathway, whereas the open circuit has at least one broken path. An open circuit is a damage in the pathway of current flow. There are two possible reasons for an open circuit – either there is a damaged cable or it is …

Also the open circuit distribution more closely follows the gradient of the cyclone overflow. If a ball mill circuit were to be fed two distributions, each with same P 80 but with the open and closed circuit gradients in Fig. 1, the closed circuit distribution would require more energy to grind to the final P 80. How much more energy is ...

This perspective comes from the practice that overall comminution is achieved by stages of crushing, followed by open-circuit rod milling and closed-circuit ball milling. Crushing is most often thought of as a semicontinuous, dry process with breakage by compressive failure, while grinding has been more typically in a continuously operating ...

Figure 3. Interestingly SMCT's data show that for HPGRs, closed circuit operation appears to require a lower specific energy to reach the same P 80 as in open circuit, even though the distributions for open and closed circuit look to have almost identical gradients.
