Claim 0:
1. A lifter bar for use in a grinding mill, the lifter bar comprising:
an elongate structural support defining a longitudinal axis and extending from (i) a first end transverse to the longitudinal axis to (ii) a second end transverse to the longitudinal axis;
a plurality of structural plates extending along the longitudinal axis in spaced relation, where each of the structural plates of the plurality of structural plates is transverse to the longitudinal axis, and each defines opposed edges; and
an elastomer enclosure surrounding the plurality of structural plates and at least partially surrounding the elongate structural support, to prevent each of the structural plates of the plurality of structural plates from being directly impacted by a grinding medium when used in a grinding mill.
