Grinding Media Charge Motion inside Mill

Grinding Media Charge Motion inside Mill

Now, clearly, in a real mill the balls which come up from the body of the ball mass must either be projected or must roll down to the toe of the charge and so, in cascading, this mathematical surface cannot represent the free surface of the ball charge.

Analysis on Grinding media Motion in Ball Mill by Discrete

It is the grinding media motion to generates the grinding effect. Normally there are two types of motion patterns that are cascading and cataracting[4]. When grinding media are moving in cascading, media move up with the mill shell till a certain height and then fall down along the surface of charge ramp.

Grinding in Ball Mills: Modeling and Process Control

The speed of rotation of the mill determines three basic types of operation modes: slow rotation (cascading), fast rotation (cataracting) and very fast rotation (centrifugation). Each type is characterized by a specific trajectory of motion of the charge in the mill and a different impact of the milling bodies on the ground material.

Ball mill Wikipedia

A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media is the balls, which may be made of steel (chrome steel), stainless steel, ceramic, or rubber.

The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile, which is known in the industry as the "angle of break." This angle can be between 40 to 65 degrees as measured from the horizontal. If the angle is too shallow, the media will not cascade much from one end to the other.

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
