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 mills produce 1 to 50 ton/h power of which near about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t. In the case of the batchoperated mill, a measured quality of a solid to be ground is charged into the mill through an opening in the shell.

The rotation of the mill and the grinding media generate a centrifugal force, which causes the balls to move along a circular trajectory. This motion further enhances the grinding action. Ball mills are commonly used in the mining industry, as well as in cement, silicate, fertilizer, refractory materials, and glass ceramics.

The principle of action of a ball mill is as follows. A rather large number of grinding bodies and the material being ground are placed inside a cylinder rotating around its central axis. Due to forces of friction between the cylinder walls and the milling bodies, the bodies start to move and grind the raw material.

The ball mill operates on the principle of impact and attrition. In this, impact occurs between fast moving balls and the powder material while the attrition mode comes in action when the hollow cylinder rotates on its longitudinal axis.
