Valmet to Rebuild Paper Machine Press Section for Marusumi Paper

The existing press section of PM 2 will be rebuilt into Valmet's OptiPress Center press section.

Nov. 9, 2015 - Valmet said that it will supply a paper machine rebuild to Marusumi Paper's Ohe mill in Japan. The rebuild includes a new press section utilizing Valmet's modern shoe press technology.

The main target of the rebuild is to decrease energy consumption at the plant.

“The trend in newsprint production has recently been towards lighter paper weights, driven by resource and energy savings,” explained Toru Shinohara, Director and Mill Manager, Marusumi Paper Co., Ltd. “To further meet this lighter weight tendency, Marusumi Paper has decided to proceed with a press rebuild project in order to improve productivity and end product quality.”

Valmet's delivery includes a new center roll based press section with modern shoe press technology as well as related runnability solutions, new press section frames, installation, motors and electrification. The existing press section at PM 2 will be rebuilt into Valmet's OptiPress Center press section. With this tri-nip solution, the new 1st press, the 2nd press and the 3rd press shoe nip maximizes the dry content, decreases steam consumption and increases the wet strength of the paper.

The 9000-mm-wide (wire) PM 2 produces newsprint grades at the design speed of 1200 m/min.

The rebuilt machine will be started up during fourth quarter of 2016.
