28.03.2013 / Metso Megaliner(TM) receives Mining magazine's award for innovativeness

Readers of the Mining Magazine have voted Metso MegalinerTM the winner of the 2012 Mining Magazine Mineral Processing award. The annual awards celebrate companies, products and projects within the mining industry that have been particularly innovative over the past year.

Metso introduced MegalinerTM Poly-Met shell liners for AG mills in 2012. The new product was the outcome of Metso's persistent research and development work to find ways to speed up mill lining installations and at the same time improve safety. The Metso MegalinerTM shell liner is now also available for use in ball mill applications. Today's large mills require quick replacement of linings because of high downtime costs. At the same time the standards are raised on installation safety. Keeping downtime in large mills to a minimum, MegalinerTM increases worker safety, as the liner is bolted into place from outside the mill, keeping workers out of the liner's drop-zone when performing maintenance.

"With MegalinerTM, mill availability is boosted by faster liner replacement. Installation is not only faster but easier, as MegalinersTM are secured with as few as half the number of attachment points as conventional liners. And with their larger than average size, fewer liners are required", says Tage Möller, Vice President, Mill Lining Solutions, Mining and Construction, Metso.

The rubber/metal composite liner weighs between 30 % and 60 % less than metallic liners of a similar size. Liner removal is straightforward, with gravity alone generally sufficient to dislodge old liners.  
Compared to the AG mill alternative, the profile of Metso's MegalinerTM for ball mills is more streamlined, with a larger face angle and lower lifter bars. Lifter bar spacing can be optimized for the best possible grinding performance and longest wear life, thanks to Megaliner'sTM larger size.
