How to Size & Design a Regrind Ball Mill
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.

What Is a Ball Mill and How Does It Work?
A ball mill and a tumbling mill are both types of grinding mills used to reduce material size. We mainly use a ball mill for mixing and grinding processes. In contrast, we generally use a tumbling mill for finer material reduction. What are the balls? Ball mills grind materials into an extremely fine form.

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.
