Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
Referring to Table VI the L/D can be between 1.75 and 2.0 or even greater. Referring to Table VII a 3.05 meter (10 foot) by 3.05 meter (10 foot) overflow ball mill with a 40 percent by mill volume ball charge, new liners and 50 mm (2″) balls draws 491 HP. Using equation 5 there will be a loss of 0.55 Kw (0.74 Hp) per metric tonnes of balls.

The ball mill is made of cylinders rotating on a horizontal shaft. They are filled with a grinding charge and fed with the material to be ground. The product is ground by impact, friction or attrition thanks to a precise rotation speed (optimised for grinding).
1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.
