The feed size of ball mill is 20 mm and the production size is 150 microns. So if you put this amounts in Bond equation you will see that the amount of power is 5853 HP. so if we divide this result with 2 we have 2926 HP to match with amount of table. It derived two ball mill with diameter and length of about 5 m. Is this calculations right?
