Increased performance, middle density alumina, providing high wear resistance in METSO SMD Mills, and reduced operating costs in High Intensity Mills.
“Keramos has saved us around AUD$2 million per year directly on media costs. The other savings are mill linings, agitator arms, maintenance costs, downtime, freight and storage. Consequently, we’ve awarded Keramos a long-term contract for the supply of their ceramic grinding media.” –
