Neikov, in handbook of non-ferrous 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.
When the amount of ore in the mills was the same, no appreciable difference between batch and continuous open-circuit ball-mill grinding was found.This should be so, because the progression in particle size for the duration of a batch run would be expected to be the same as the progression from the feed to the discharge ends in a continuous run.Table 10 illustrates the marked similarity of.
