· re REGARDING % OF GRINDING MEDIA IN THE MILL. Best for reference for ball mill. MILL CHARGE VOLUME VOLUME LOADING (%) =113 (126 *H/D) H Empty height above grinding media. D Effective Dia of mill.
· In semiautogenous grinding (SAG), the grinding mill inventory, ( volume of total charge, volume of ball charge, etc.) is important in determining the optimum operating condition for maximum production (tph), minimum specific energy (kwh/t) or lowest cost (/t). A twodimensional graphical method is presented for determining the actual ball charge within the total charge when .
· We draw your attention, a larger grinding balls need to use for future loads. As practice shows, the difference between the grinding balls average diameter in mill and loaded grinding balls diameter is 1015 mm. In our example, the grinding balls diameter needed to load into the mill must be equal to 4050 mm. Let's sum up.
