Case Study: Jeonju Paper restores PM7 stability with Valmet's on-site vibration analysis

Jeonju Paper restores PM7 stability with Valmet after eliminating vibration at the 4P roll position

Jeonju Paper, a paper mill in South Korea, faced a challenge when abnormal vibration was detected at the PM7 4P roll position, risking mechanical issues and unplanned downtime. To identify the root cause and maintain operational stability, they engaged Valmet for an on-site technical assessment and vibration analysis service.

Valmet's specialists conducted on-site vibration measurements and a detailed drive-system analysis. They identified a faulty universal joint as the source of the problem and provided a clear recommendation. Following the replacement of the universal joint, the vibration was eliminated and stable operation was restored. This solution allowed Jeonju Paper to focus its resources effectively and improve machine reliability, demonstrating the value of Valmet's condition monitoring and troubleshooting expertise.
