Ball Mill (Ball Mills Explained)
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

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.
Ball Mill
According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill, L/D ≥ 1–1.5 or even 2–3; and tube mill, L/D ≥ 3–5. According to the cylinder shape of the ball mill, it can be divided into cylindrical ball mill and cone ball mill.
What Is The Mechanical Design Of A Ball Mill?
