Aug 08, 2018 There are two well-known modes in which the ball charge moves inside the mill cascading and cataracting. The cascading motion of ball charge forms a compressive zone inside the mill where particles may break under slow compression. The cataracting motion, on the other hand, causes the particles to break under high-impact forces.
