What Is The Working Principle Of The Ball Mill?
The ball mill achieves material grinding by the movement of its internal grinding medium (usually steel balls, steel forgings, steel bars, pebbles, gravel, ceramic balls, etc.) inside the cylinder. When the ball mill rotates, the grinding body adheres to the lining surface of the inner wall of the cylinder under the action of centrifugal force and frictional force generated with the lining surface of the cylinder. It rotates together with the cylinder and is brought to a certain height before falling freely. When falling, the grinding body impacts the material at the bottom like a projectile, shattering the material. The grinding body will also slide and roll inside the cylinder, thereby grinding the material and making it finely ground. Due to the continuous feeding of new materials at the feeding end, there is a material level difference between the feeding and discharging ends, which can force the material to flow. In addition, the axial thrust generated by the impact of the grinding body on the material when it falls also forces the material to flow.
