  • TECHNICAL SPECIFICATION FOR LIMESTONE GRINDING

    Limestone is fed by gravimetric feeder from limestone silo to wet ball mill. The limestone slurry 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. As the mill feed becomes finer the greater the feed rate for the same power consumed considering a P 80 of 300 µm (Figure 2 and Table 3). In the ball compartment such behaviour is also influenced by the decrease in WI as the blend becomes finer. Figure 2 Results of the evaluation of the samples when feeding the mill
