Working: At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.

The axis of the shell may be either horizontal or at a small angle to the horizontal.
The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material. The shape of drum liners has a significant impact on mill's work. Drum Liners of ball mills operated on a large source material have ribs.
