Referring to Table VI the L/D can be between 1.75 and 2.0 or even greater. Referring to Table VII a 3.05 meter (10 foot) by 3.05 meter (10 foot) overflow ball mill with a 40 percent by mill volume ball charge, new liners and 50 mm (2″) balls draws 491 HP. Using equation 5 there will be a loss of 0.55 Kw (0.74 Hp) per metric tonnes of balls.
These mills use a unique grinding mechanism that involves rotating metal fins moving at high speeds to pulverize grains.
