oleg 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
ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills is typically vol.-% ore and 25% steel. the ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
the number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in sag mills. the increased frequency is due to the increase in charge volume higher mill speeds, and the larger number of balls per unit charge weight.
