Grinding Media Charge Motion inside Mill - 911 Metallurgist

Nov 07, 2016  Cataracting Motion. The motion of the charge, that is the grinding media and the material undergoing grinding, within a mill is of considerable theoretical interest and practical importance, and for these reasons, has been the subject of considerable study by a number of workers, but, even so, no rigid and complete theory, covering all the ...

How Ball Mills Lifter Bar Affects Charge Motion

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.
