Abstract: in semi-autogenous grinding (sag), the grinding mill inventory, (i.e. 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 two-dimensional graphical method is presented for determining the actual ball charge within the total charge when.
Abstract: particle grinding is a final stage in the comminution process used to liberate minerals from gangue in mineral processing plants. semi-autogenous grinding (sag) occurs in tumbling mills which use both large ore particles and steel balls for grinding. grinding is the most energy intensive mineral processing unit operation and hence its optimisation is of considerable interest to.
