Abstract The disclosure is directed to an improved liner assembly for an ore grinding mill. The liner assembly is of the segmented type, comprising a first plurality of holder segments which are mounted directly to the shell of the mill, and a second plurality of wear segments which are mounted to the shell in overlying relation to the holder segments, which are thus virtually unexposed to the ore comminution process and wear very slowly. The wear segments are formed with a plurality of downwardly pro- jecting bosses which are received in similarly configured recesses formed within the holder segments. Mounting openings or bores are formed in the wear segments, ex- tending from the top grinding surface to the center of each boss to receive a mounting bolt that extends through both segments and projects externally of the shell to receive a threaded lock nut. These mounting openings are countersunk so that the heads of the mounting bolts securing the wear segments are substantially recessed from the grinding surface. The holder segments are secured directly to the shell by identical mounting bolts through mounting openings which are protectively covered by the wear segments to preclude exposure to the ore fragments during the comminution process.
