TECHNICAL NOTES 8 GRINDING R. P. King
2009-7-30 The effect of mill charge is primarily through the shifting of the center of gravity and the mass of the charge. As the charge increases the center of gravity moves inward. The power draft is more or less symmetrical about the 50% value. A simple equation for calculating net power draft is P 2.00 3 cD 2.5 m LKl kW (8.12)
