The large mills of today process high tonnages, and every minute of production counts. Proper material selection, optimized lining design and constant design improvements are the keys to successful grinding. Metso offers steel linings that keep your mill running at top efficiency. Features Metso metallic mill linings are produced at our own foundries with very strict quality controls. Our Cr-Mo steel and high-chromium white iron alloys are specifically developed for mill lining applications and are carefully selected based on the operating conditions of each application.
