Know

1.Feeding speed. Most ball mills can be controlled manually or automatically. No matter which way you choose, the velocity should be uniform. 2. Feeding size. The relationship between feeding size and ball mill capacity varies with mineral properties. In heterogeneous ores grinding, the finer the mineral slurry, the higher the ball mill capacity.

AMIT 135: Lesson 7 Ball Mills Circuits

It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n where n = 0.3 to 0.5. It is evident that mill power is a function of the height at which the media is lifted and the density of the media, i.e., PM = K ρ b LD 2.5 where k is a proportionality constant.
