Overview of Ball Mills. As shown in the adjacent image, a ball mill is a type grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It's called a "ball mill" because it's literally filled with balls. Materials are added to the ball mill, at ...

Each time the grate enters the mill charge, the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge, the rubber assumes its original shape. This diaphragming action works the large particles ...

The power draw is driven mainly by mill diameter and length, ball and slurry charge level, and rotational speed. But the slurry charge in an overflow ball mill doesn't change very much because most of the slurry occupies the void space in between the balls, so as the circulating load increases, the discharge rate also increases.
