SKF Performance Contracts for Horizontal Grinding Mills

For many producers in hard rock mining, the horizontal grinding mill is the most critical asset, and unplanned outages have a major impact on uptime and the cost of operations. Increase availability for the mill by reducing the risk of failures and unplanned stops to improve KPIs – extending the mean time between failures is a sure way to reduce the cost per ton.
