Abstract
A discharge end liner attachable to a discharge end wall in a grinding mill. The discharge end liner includes a number of pulp lifter elements mountable on the discharge end wall for at least partially defining a number of chambers rotatable in the predetermined direction respectively between a submerged condition and a raised condition. The discharge end liner also includes one or more grate subassemblies positionable on the pulp lifter elements, for at least partially screening the slurry. At least a part of each grate subassembly is located by an outer portion of the pulp lifter element in a predetermined position relative to the discharge end wall. An inner portion of each pulp lifter element defines an obtuse angle between the inner portion and the outer portion, for permitting the retained portion of the slurry to evacuate from each chamber respectively while each chamber is in the raised condition.
