2019-10-29  Failure Analysis of Ball Mill Liner-Goldpro-First, the 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 end, the mill liner is required to have sufficient lifting and disturbing ability for the grinding ball.

It is fully explained that the mill load is too small, the feed quantity is too small, and the steel ball impacts the liner for a long time, resulting in fracture.

Dramatic shortcomings of mill liner designs, especially of large SAG mills, - such as rapid failure and even mill shell damage arising from impacting of the charge directly on the liner, and unsuitable spacing of lifter bars yielding unfavourable compromises between lifter bar height and liner life - have highlighted the significance of correct mill liner selection. Liners protect the mill shell from wear and
