Works for batch or continuous operation (as well as closed-circuit grinding) suitable for a wide range of materials simple design ensures less repairs . Whether you are in the market for a used ball mill for your business or you have a pre-owned ball mill you’d like to sell, USA-based Phoenix Equipment can help.
The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution water flow rate. Attempts to use this for density control were not successful. Because of the high magnetite concentration of the ore it was found that the actual density exceeded the required density,.

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.
Question 2. In a reverse closed-circuit ball mill-classifier circuit the new feed enters the classifier, the classifier oversize is fed to the mill, the mill discharges to the classifier, and the classifier undersize is the finished product of the grinding circuit. The following are the sieve analyses of the streams of such a circuit.
