Condition-based roll maintenance mindset at Anhui Shanying

Dec 1, 2021

In 2016, Shanying International invested in Valmet’s online condition-monitoring system to monitor the key rolls of five paper machines at Anhui Shanying in China. To ensure effective maintenance and troubleshooting, a comprehensive Roll Service Agreement initiated in 2017 has recently been renewed. The aim of condition monitoring is to eliminate problems in the early stage to enable efficient operation and maintenance practices to extend roll lifetime.
