Principle of ball mill. The ball mill works on the principle of impact between the rapidly moving balls and the powder material, both enclosed in a hollow cylinder. At low speeds, the balls roll over each other, and attrition (rub bing action) will be the predominant mode of action. Thus, in the ball mill, impact or attrition or both are ...
