Ball Mill Principles Ball mills, sometimes referred to as pebble mills or tumbling mills, are milling machines that take the form of cylindrical vessels containing balls mounted on a metallic frame that can revolve around its longitudinal axis. Depending on the feed and mill size, balls with varying diameters occupy 30 - 50 % of the mill volume.

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 ...
