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 ...

Ball Mill Working Principle. The working principle of a ball mill is based on the impact and attrition between the balls and the grinding media. As the mill rotates, the grinding media (usually steel or ceramic balls) are lifted to a certain height and then allowed to fall freely, causing the materials to be reduced in size by the impact and ...
