Continues Ball Mills With Close Circuit. Continues Ball Mills With Close Circuit. Closed Circuit Ball Mill Basics Revisited Sciencedirect. Based on experience acquired over the years and the investigative work conducted by F.C. Bond, it was established that the optimum circulating load for a closed ball mill cyclone circuit is around 250%.

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 ...

Based on experience acquired over the years and the investigative work conducted by F.C. Bond, it was established that the optimum circulating load for a closed ball mill – cyclone circuit is around 250%. This value is used as guideline for the design of new circuits as well as to assess the performance of existing circuits.

There are two basic types of ball grinding systems: open circuit and closed circuit. In the open circuit system, the mill product has the fineness required for the next stage. In the closed-circuit system, the mill product is classified in a separator in a fine fraction that is then taken to the next step and a thick fraction that is returned ...
