All mineral grinding mills suffer high wear rates of their internal components. All cylindrical tumbling mills (AG, SAG, Ball and Rod Mills) feature cylindrical structural shells, protected from abrasion by removable, replaceable mill liners. Every tonne of mineral ore must be processed through the grinding mills.
