New testliner line for Henan Longyuan Paper in China

Key technologies and automation systems for Henan Longyuan Paper’s new PM7 testliner line at its mill in Henan province in China have been ordered from Valmet. The order also includes a quality control system for the rebuild of the mill’s PM3 machine.

“The good cooperation with Valmet started with the headbox installation project for PM6,” said Yuzhou Wang, vice general manager of Henan Longyuan Paper.

“Valmet’s intelligent technology operating with low carbon emissions fits perfectly together with Henan

Longyan Paper’s efficient and environmentally-friendly concept, contributing to the local economy. We are looking forward to collaborating with Valmet again.”

The delivery includes a bottom dilution headbox and a Tri-nip press section and an automation package, including DNA machine controls (MCS), IQ Quality control system (QCS), dilution profiler for headbox, steam profiler, as well as Valmet services.

After the installation, PM7 will produce testliner products with a basis weight between 90-140 g/sqm and a design speed of 1,100 metres per minute.
