2009-8-27  The only manipulated variable available in the closed millingcircuit (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 wasfound that the actual density exceeded the required density,causing the density control loop to become unstable. If theoperator did not intervene at this stage, the dilution water tocyclone would close
