Working of Ball Mill. The ball mill works by introducing the material to be ground into the feed hopper. The material is then pulled into the mill by the rotation of the drum. As the drum rotates, the balls inside the drum strike the particles, breaking them down into smaller pieces. The ground material is then discharged through the discharge ...

The operating principle of the ball mill consists of the following steps. In a continuously operating ball mill, the feed material is fed through the central hole into the drum (shell) and moves there along with grinding media (balls). : Cascade Operation in Ball Mill (a) Low Speed (b) High Speed (c) Correct Speed

Ball Mill Principle. Ball mills are a type of grinder used to grind and blend materials for use in various industries. The basic principle of ball mills involves two or more grinding media, such as balls or rods, rotating in a container to grind materials to a desired fineness. The principle of ball mills is based on impact and attrition.

It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls.
