Abstract The Selection and Design of Mill Liners

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
