The working principle of the ball mill is to rotate the horizontal cylinder to drive the internal grinding body (usually a steel ball) to move. When the grinding body is brought to a certain height, it falls due to gravity, and the falling grinding body crushes the material in the cylinder like a projectile. In addition, during the rotation of ...

The Working Principle Of A Ball Mill
