  • Grinding control strategy on the conventional milling

    2009-8-27 · 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,MILLING CONTROL & OPTIMISATION,2012-2-7 · MILL FEED CONTROL. Smooth operation of a milling circuit is difficult to achieve due to: • The varying nature of the feed material (size, ore hardness, etc.). • The unfavorable dynamics between feeders and the weightometer. These dynamics degrade the performance of PID controllers, making feed optimisation more challenging.
