How Ball Mills Lifter Bar Affects Charge Motion 911 Metallurgist

How Ball Mills Lifter Bar Affects Charge Motion 911 Metallurgist

There are two wellknown 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 highimpact forces.
