Abstract
A liner system for installation in a rotatable mill shell having an inner side and an opposed outer side, the liner system including one or more lifter bars. The lifter bar includes a body, a channel plate secured to the body and defining a channel axis, including one or more lateral extensions extending transversely from the central portion in relation to the channel axis, and one or more insert elements positioned between the lateral extension and the inner side of the mill shell, for resisting outward movement of the lateral extension toward the inner side. The liner system also includes one or more attachment assemblies, each including a bolt, for securing the lifter bar to the mill shell. The insert elements are configured to maintain the bolt in a predetermined position in which an axis of the bolt is aligned with the channel axis.
