A low cost, high performance alumina media, providing exceptional wear resistnace for the low density requirement, ideally suited for use in METSO SMD 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.”
