Nine Dragons Industries invests more than EUR 100 million into expansion of containerboard production at its Quanzhou and Chongqing mills in China. The company placed an order with Valmet for two containerboard production lines able to produce high-quality testliner and fluting grades out of 100% recycled raw materials. The start-ups of the machines are scheduled for 2018.

PM 39 in Quanzhou mill and PM 40 of Chongqing will produce testliner and fluting grades with a basis weight range of 75 – 140 g/m2.

According  to the announcement, both board machines will include pulpers for stock preparation, two OptiFlo Fourdrinier headboxes to ensure higher productivity, OptiFormer Multi forming section, a center-roll based OptiPress press section, a dryer section with OptiAir high humidity hood combining systems for ventilation, runnability and heat recovery, OptiSizer Combi, a sizer with film and pond application, coating air dryers, OptiCalender Hard nip calender, OptiReel Center driven linear reel and OptiWin Drum two-drum base winder. The scope of the equipment supplier also includes process ventilation equipment for the board machine and Valmet DNA machine control system.
