Zinkgruvan Mining AB in Askersund/Sweden, has signed a new Life Cycle Services (LCS) agreement with Metso. The agreement covers mill lining and related services for five grinding mills and is valid for three years. A “cost per ton” agreement ensures that both Zinkgruvan’s and Metso’s goals are aligned for maximum production as well as safer operations, and is a result of the longstanding partnership between the companies. Under the new LCS contract, five mills in total, including a new autogenous mill that was commissioned in April of this year, will be maintained and serviced at Zinkgruvan. The new mill is expected to help increase production by 10 %. The order was booked in Metso’s first-quarter 2017 orders received.
Metso has delivered most of the process equipment for the mine and is working with the entire process, from crushing, grinding, and beneficiation to finished metal concentrate. There are normally three fixed maintenance shutdowns per year. Every stoppage costs money and therefore all unplanned downtime needs to be avoided. HSE work is the main item on the daily agenda at the mine. Metso’s service personnel are also actively working to find new measures to improve safety. As an example of extra precautions, there is a protective structure built around the mill during a maintenance shutdown.
