Abstract: A grinding mill including one or more lifter bar assemblies mounted on a shell rotatable around a central axis thereof. Each lifter bar assembly is for lifting at least a lifted portion of a charge including ore, and includes a main portion for lifting and directing a main part of the lifted portion in a main part direction substantially orthogonal to the central axis of the shell. The lifter bar assembly also includes one or more terminal lifter bars located proximal to one or both of feed and discharge ends of the shell, for lifting and directing terminal part(s) of the lifted portion of the charge. The terminal lifter bar is positioned for directing the terminal part of the lifted portion of the charge at least partially in a terminal part direction which is substantially non-aligned with the main part direction.
