Abstract (en)
A wear liner element (30, 30') for a grinding mill is provided with an expandable ejector unit (50) to be arranged between the outer surface of the wear liner element (30, 30') and the opposite inner surface of a shell or an endwall of the mill. The ejector unit (50) has a first part for abutting or engaging with the outer surface of the wear liner element (30, 30') and a second part for abutting or engaging with the inner surface of the shell or endwall and is operable to increase a spacing between its first and second parts to thereby increase the spacing between the outer surface of the wear liner element (30, 30') and the inner surface of the shell or endwall.
