A new procedure and apparatus for securing shell liners in ball and bar mills. The liners are formed with sockets of special shape at predetermined intervals therealong, and are held within the shell of the mill by bolts having heads, received in the sockets, and threaded shanks passing through the liners and the mill shell to nuts on the outside. The sockets and heads are shaped to provided continuous flat contact areas of substantial size regardless of variations in center distances of holes axially along the shell (i.e., the mounting holes are larger than the mounting bolt heads).
