Introduction to Ball Mill Inside. A ball mill is a cylindrical drum that rotates around its axis, which is usually horizontal. Inside the cylinder, there are steel balls of different sizes that are used to grind the material. The material is fed into the mill through a hollow trunnion at the end of the cylinder.
