Ball Mill Liner Replacement / Ni Hard Liners Sand Cast Process EB17019

AS2074 L2B Pearlitical Cr-Mo Alloy Steel SAG Mill Liners Sand Cast Process EB17019

SAG mill liners development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e.

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 transfer energy to the grinding charge, and a careful balance is required to optimise these conflicting requirements. This review serves to highlight these problems and how they can be tackled in a logical and often inexpensive manner by considering charge trajectories and liner spacing criteria, in conjunction with liner wear monitoring.
