A. Jankovic, in Iron Ore, 2015 Ball mills The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.

Ball Mill Working Principle. In the case of a continuously operated ball mill, the material to be ground is fed from the left through a 60° cone, and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down from near the top of the shell

Principle A ball mill works on the principle of impact and attrition. size reduction is done by impact as the balls drop from near the top of the shell. Ball mills rotate around a horizontal axis, partially filled with the material to be refined plus the grinding medium. An internal cascading effect reduces the material to a fine powder.
