From wet ball mill shall be discharged to mill overflow tank grinding water for the limestone ball mill shall be ratio controlled by the signal of gravimetric feeder to maintain specified solid content at outlet of mill hydro cyclone limestone slurry from mill overflow tank is pumped via mill circuit pump to hydro cyclone for classification
Depending on the nature of the feed and the circulating load at times the discharge of the ball mill may get choked this is indicated by the continued reduction in the discharge rate from the mill in such case often there is a tendency to increase the water flow rate inside the ball mill to flush out the choking amterial in many cases it
