The mill comprises a cylindrical shell (16) lined with an interior lining and intended to contain material to be ground and a charge of grinding implements, in which the lining, which is made up of rings of juxtaposed individual lining plates, has interior longitudinal lifting profiles to encourage the lifting of the charge and of the material to be ground as the mill rotates. In order to adapt the lifting profile to the parameters and conditions in which the mill operates, each plate has, on the rear face, when viewed in the direction in which the mill rotates, a step (10b, 12b, 14b) of a radial height that is taller than the front face, and each ring of plates comprises several different types of plate (10, 12, 14) which differ at least in terms of the radial height of their step (10b, 12b, 14b) and which follow on from one another, in the circumferential direction, in a determined order. |
