    multi-stream plants, where mill liner design and selection is only tackled on a cost consumables basis. However, the gains to be had through good liner design and selection are just as great as on the large SAG mills. This paper looks at recognising problems in liner design and selection in existing operations, and then at liner selection for new applications. TYPES OF LINERS . Design and
