Ball Mill Overview
A ball mill is a type of 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. Material is added to the ball mill, at which point the balls are bumped around inside the ball mill.
How does a ball mill work?
The working principle of the ball mill is to use balls to grind materials. Add iron ore, bitter material, ceramics and other materials into the ball mill. Next, the ball mill is activated, causing it to rotate on a vertical or horizontal axis. As the beak spins, the ball bounces around while striking the enclosed material. The force of these impacts helps to grind the material into finer and coarser media.
For the ball mill to work, it must reach a critical speed. The critical speed refers to the speed at which the closed ball starts to rotate along the inner wall of the ball mill. If a ball mill cannot reach critical speed, the balls will remain stationary at the bottom where they have little or no effect on the material.
