causes and solutions of ball mill noise |mining pedia

The work of the impact force has a great relationship with the diameter of the steel ball and the diameter of the mill cylinder. If the liner material is of poor quality and unevenness, there will be a mismatch between the liner and the liner, the liner, and the cylinder wall, which directly affects the normal operation of the ball mill.
