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 ...

Optimum filling ratio. U= (volume of powder in the mill)/ (volume of voids in the charge): between 60% and. 110%, optimum around 90%. In practical terms, material level should equal ball level in the first compartment. In practical terms, material level should be higher than ball level in the second.
