What Is a Ball Mill? - Monroe Engineering

What Is A Ball Mill? - Monroe Engineering

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. ball mills work by using balls to
