Abstract The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110 kWh/tonne, and around 40% of this energy is consumed for clinker grinding. There is potential to optimise conventional cement clinker grinding circuits and in the last …

cement mill optimization. i have a polysius ball mill with capacity 110 tph. normally i get blaine at mill outlet around 200 while my product blaine target is 400 . separator reject baline is around 90 . i think i should put more smaller grinding media in ii chamber to increase the fineness at mill outlet to obtain 230 to 240 blaine.
