ABSTRACT:
A longitudinal metal liner element is provided for lining the interior peripheral wall of a grinding mill. The metal liner element is formed of a plurality of longitudinal segments having inclined end faces such that the segments are cooperably longitudinally arrangeable with the inclined end faces thereof in end-to-end overlapping relationship. The overlapping inclined end faces of the segments are configurated to diverge towards the interior of the mill such that when the segmented liner is secured to the inner peripheral wall of the grinding mill and is subjected to the working stresses of grinding media in the mill, the stresses applied to the metal liner result in the generation of a vertical lifting force at the overlapping end faces due to linear strain along the liner which aids in the subsequent removal of the segments for maintenance purposes.
