Failure Analysis of Ball Mill Liner-Goldpro-Firstthe main function of the ball mill liner is to protect the mill barrel and drive the grinding ball inside the grinding to do the sloping movement to smash the material in the crushing mill. To this endthe mill liner is required to have sufficient lifting and disturbing ability for the grinding ball.
Abnormal noise during ball mill operation is one of the most common problems in ball mill failure. It is mostly caused by loose parts in the mill. When you hear the ball mill has abnormal noisestop feeding the mill. After the material in the mill is groundstop the mill for inspection.
2. Improvement measures for the wear of ball mill liner 1 . Select reasonable steel ball and liner. The hardness of ball mill lining plate and steel ball should be controlled within a reasonable range. The ball diameter of steel ball should be set reasonablyso as to prevent friction between liner and steel ball and cause wear. 2 .
