Finnish company Metso will take complete responsibility for the supply, installation and optimisation of Kevitsa mine’s mill liners. Metso and Kevitsa’s common goal is to increase the mill’s availability and production efficiency and to reduce the total cost of ownership, Metso said.

“This solution will raise our utilisation rate to a new level and will contribute significantly our sustainable competitiveness in the challenging market situation,” said Timo Ikäheimonen, Kevitsa planning manager. 

Under the deal, Metso is aiming to increase the time between shutdowns through optimization of wear-parts selection as well as decreasing the duration of shutdowns.  Metso will reduce shutdown times through advanced planning and the delivery of its patented Megaliner grinding mill wear parts. 

Thanks to the fast installation process of Metso's Megaliner, downtime is reduced, the company said. Additionally, the use of Megaliner parts in grinding mills increases work safety as the attachment parts are inserted from the outside of the mill. With this set-up there is no need for the workers to be in the danger-zone of the liners while installing liner bolts.

“We aim to reduce the concentrator plant downtime, secure availability and commit ourselves to the continuous development of enhancing the plant's operations," commented Olli Kellokumpu, sales director, Finland, minerals at Metso.

Installation will begin in the latter part of 2015. The agreement will be booked in phases into Metso's orders received throughout the term of the agreement.
