### Ball Mill Design/Power Calculation

The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill gives the optimum composition of 40 50.8 mm ball and 60 25.4 mm balls for a 1 m diameter mill and 27 50.8 mm and 73 25.4 mm for a 2 m diameter mill when grinding from a 90 passing 9.5 mm feed to an 80 passing 150 μm product. The portion of 50.8 mm balls decreases as the feed size or the product size
