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.Web

Ball mills can be classified into high-energy ball mills and low-energy ball mills by their rotation speed. Selection of certain ball mill depends on used technique; MA, MM or MD.
