How to Handle the Charge Volume of a Ball Mill .

As a result, mills are seldom run with charge levels greater than 45%. In rod mills, the charge is swollen by particles of feed which separate the rods. If the mill is shut down immediately after the feed is shut off, the charge level will be greater than if the mill had been "ground out" prior to shutdown. Because of this, rod mills .

TECHNICAL NOTES 8 GRINDING R. P. King

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) Kl is the loading factor which can be obtained from Figures 8.5 for the ...

How to Handle the Charge Volume of a Ball Mill .

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill.To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of ...
