Operating Principles of Ball Mill Description of How a Ball Mill Works. A ball mill operates by rotating a cylinder with steel or ceramic balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation of the cylinder is typically between 4 to 20 revolutions per minute, depending on the diameter of the mill.

Ball bearings are used to provide smooth, low friction motion in rotary applications. Ball bearings are able to provide high performance and long lifetime in order to transfer the load from the balls to the inner races. The balls have minimal contact with the inner and outer races due to their spherical shape and this allows them to spin smoothly.

Operation of Ball Valves in Pneumatic Systems. Ball valves work on a straightforward principle: the media flow is controlled by the rotating spherical disc inside the valve body. When the handle or actuator is turned to the open position, the ball rotates to match the disc's hole with the flow path, allowing media to pass through. ...

The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
A ball bearing is a type of rolling-element bearing that serves three main functions while it facilitates motion: it carries loads, reduces friction and positions moving machine parts. Ball bearings use balls to separate two "races," or bearing rings, to reduce surface contact and friction across moving planes.
