### motion of charge in tumbling mill

Optimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput. Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimising ... first ones to track the motion of the ball charge in large-diameter ball mills using DEM simulation. Later, Powell and McBride 3 illustrated the media motion and grinding regions (head, departure shoulder, center of circulation, equilibrium surface, bulk toe, and impact toe). ... The power consumption of a ball mill is one of the
