There are different points for measuring density in the grinding circuit. One of the applications is to monitor the dillution of material in the ball mill discharge, to improve the efficiency of the process. Another important application is to monitor changes of density in the cyclone underflow, this can be done to check the process stability and increases or decreases of circulating load.
Water impacts the grinding process, therefore the efficiency of the ball mill can be greatly improved by better water dosage. This alone could improve the efficiency with 5-15% according to 911 mettalurgist. When this is combined with a control strategy, the improvement rate could be even higher.
