Ball Mill Principle, Application, Uses, Critical Speed, Diagram ...

The critical speed of a ball mill is the speed at which the centrifugal force is equal to the gravitational force acting on the balls. At this critical speed, the balls are held against the inner wall of the mill and do not fall to the bottom where they would be more effective at grinding the material.

If the mill is operated at very high speeds, the balls are carried right around in contact with the side of the mill, and the mill is said to be centrifugal. The minimum speed at which centrifuging occurs is called the critical speed of the mill, and under these conditions, centrifugal force will be exactly balanced by the weight of the ball.

The working principle of ball mill Meetyou Carbide

The working principle of ball mill Meetyou Carbide

The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact ...
