| Abstract: |
| An industrial closed-circuit comminution process is basically composed of comminution and classification operations. Eased on models of unit operations and the population balance principle, a new modeling approach was established for a generalized circuit configuration. The two most commonly used configuration of closed-circuit grinding can then be treated as special cases of this general circuit configuration. The steady-state simulation of a closed-circuit grinding process for interparticle breakage using this approach shows that the calculation results agree very well with the results obtained from laboratory locked-cycle tests. |
