Abstract
A liner assembly for the shell or drum of an ore grinding machine is disclosed with an insert used to facilitate its removal. The liner assembly comprises a plurality of liner segments mounted in side-by-side relation, with adjacent liner segments defining a pocket therebetween of generally triangular configuration. A wedge-shaped insert is disposed within each pocket to reduce the amount of particulate matter entering the pocket and to protect the inner surface of the shell. The wedge-shaped insert is formed from resilient material and includes a recess or groove taking the form of an inverted V extending upwardly from its bottom surface. The recess enables the insert to internally collapse if the pocket is of lesser cross-sectional dimension than that of the insert.
