WEBAug 8, 2018 · There are two wellknown modes in which the ball charge moves inside the mill: cascading and aracting. The cascading motion of ball charge forms a compressive zone inside the mill where particles may break under slow compression. The aracting motion, on the other hand, causes the particles to break under highimpact forces.
