The volumetric filling degree of modern finish mill is 27-30% for the first chamber and 24-27% for the second chamber.In your specific case first chamber may be loaded 114.76 MT- 127.52 MT and in second chamber you may load 197.91 MT - 222.65 MT.You should start media loading in both the chambers from lower value first and based on grinding performance you may increase the load in phase manner.Grinding media density for first chamber you should take 4.3 t/m3.
