Modern mills operate with load cells and mill optimizer's which synchronize the mill weight, power draw, ore feed and weight with density control. Where optimizers are not used, the rule of thumb for a overflow ball mill is a ball load up to about 12 inches below the trunnion discharge- this allows bed expansion by the slurry filling the voids ...
mill load, taking photographs from load surface and distributing load surface results to whole mill load and mill load sampling. However, sometimes due to plant condition limitations, some of these ways are impossible. A simple equation (Equation 1) exists for load percentage calculation that belongs to mill diameter (𝐷𝑚

Though, there are small differences in the mill speed (N: 0.6 versus 0.7) and ball load (J: 0.5 versus 0.4), in our opinion the main factor is the ball size distribution: a single size ball charge versus a ball charge made up of balls of three different sizes. The void space in the ball charge, the relative movement of different layers of balls ...
Re: Ball Mill Load & feed. Dear Bhasker Agate. When mill is going in chock condition mill main drive kw will reduced due material is not ground .but you say kw m.d will increased. Main drive kw only increase when less grinding media charge and small size of grinding media with respect feed size and feed rate ( due to material not pass through ...
