Claim 17:
18. A grinding mill comprising:
(i) a shell,
(ii) a plurality of lifter bars 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 structural plate is transverse to the longitudinal axis, and defines opposed edges, and
an elastomer enclosure surrounding the plurality of structural plates and at least partially surrounding the elongate structural support, to prevent the structural plates from being directly impacted by a grinding medium when in use,
the plurality of lifter bars being mounted on an inner surface of the shell in circumferentially spaced relation, and

(iii) at least one shell liner mounted between adjacent lifter bars.
