Oleg d neikov in handbook of nonferrous metal powders 2009 tumbling ball mills tumbling ball mills or ball mills are most widely used in both wet and dry systems in batch and continuous operations and on a small and large scale grinding elements in ball mills travel at different velocities therefore collision force direction and kinetic energy between two or more elements vary
Balllimited circuits where the t 80 hits the lower limit will result in the charge level in the sag mill dropping until its power draw matches the throughput limit dictated by the ball mill it is important to realize that once the sag mill charge level drops to be equal to the ball charge the model will be operating "out of range" and the
