    It is the grinding media motion to generates the grinding effect Normally there are two types of motion patterns that are cascading and cataracting When grinding media are moving in cascading, media move up with the mill shell till a certain height and then fall down along the surface of charge ramp Rock material is grinded in the procedure of the media uprolling and downrolling While media tumble down to the bottom of the mill, partial impact the toe region, but the primary grinding effect is produced by slight impact in cascading On the other hand, under the circumstance of cataracting, after media rose to that height, they could be a projectile in a trajectory During the trajectory falling, there is no relative movement between grinding media and rock materials for their falling at the same velocity However, the impact of charge hitting the toe will be much stronger than what was mentioned above In cataracting,
