- 9434 simulation of charge motion in ball mills part 1

Many unobservable facts about charge motion are revealed by this simulation approach: It is shown that larger balls segregate to the center at high speeds and to the shell at lower speeds. The frequency of collisions in a 4.75 m diameter mill mostly lie within one joule. The friction between the ball charge and the mill shell can increase the ...
