Ball Mills - an overview | ScienceDirect Topics

The ball mill is a cylindrical drum (or cylindrical conical) turning around its horizontal axis. It is partially filled with grinding bodies: cast iron or steel balls, or even flint (silica) or porcelain bearings. Spaces between balls or bearings are occupied by the load to be milled.

What Is a Ball Mill? - Monroe Engineering

2020-3-10 · 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 which point the balls knock around inside the mill. How a Ball Mill Works
