Valmet containerboard lines for nine dragons

Valmet will supply two containerboard production lines and related automation systems for Nine Dragons Industries Co., Ltd. in China. The new lines (PM 39 in Quanzhou and PM 40 in Chongqing) are to use 100% recycled raw materials to produce high-quality testliner and fluting grades in a basis weight range of 75 - 140 g/m2. Start-ups are scheduled for 2018.

Valmet says the typical value of an order of this type and scale is around €110-130 million. The delivery will include LED lighting and video screens at both ends of the machine. In addition to increasing safety and usability, they have a positive effect on the customer’s brand, says Valmet.

Both machines will include: pulpers for stock preparation; two OptiFlo Fourdrinier headboxes for high productivity; an OptiFormer Multi-forming section; a center-roll-based OptiPress press section; a dryer section with OptiAir highhumidity hood combining systems for ventilation, runnability and heat recovery; an OptiSizer Combi sizer with film and pond application; coating air dryers; an OptiCalender Hard-nip calender; an OptiReel Center-driven linear reel; a high-capacity OptiWin Drum two-drum base winder. Also included are process ventilation equipment and Valmet DNA machine control systems.

With the OptiReel center-driven linear reel, the parent reel is moved and built up on solid rails. This new technology increases productivity and improves safety and usability, says Valmet. The OptiWin Drum two-drum base winder has Dual Unwind enabling the parent roll to be changed in only one minute.

Founded in 1995, Nine Dragons Paper Group claims to be the world’s largest recovered paper based paper manufacturer in terms of production capacity. The group produces printing and writing paper in Dongguan and Taicang and packaging paperboard and specialty paper in Leshan, Sichuan Province. The group has also acquired 100% control equity interest in Hebei Yongxin Paper Co., Ltd.
