In 2011, the world’s largest and fastest woodfree-producing paper machine was started-up at the Zhanjiang Chenming mill in China. During its first operational year, it achieved on several occasions a new world speed record. In November 2012, the recorded speed was 1,808 m/min. During a 24-hour run, the 11.15-meter-wide PM 1 produced high quality printing paper at a basis weight of 70 g/m2.
Valmet’s full-scope supply Zhanjiang Chenming PM 1 is wide and large and comes equipped with the very latest technology. In addition, in terms of energy and raw material consumption/produced tonne of paper, it is also an economical and ecological paper machine.
This world record-holding paper machine features the latest in technological innovations for improving machine efficiency, runnability, paper quality, and raw material efficiency. For example, the new OptiFormer Gap with shoe and blade technology has all the tools required for managing excellent formation at high machine speeds in a wide basis weight range.
Revolutionary OptiDry Twin impingement drying technology offers the possibility to radically reduce machine length, leading to savings in construction work; however, it can also be used to increase bulk, save raw materials, and reduce paper grammage.
With all its featured high technology, environmental care, and exceptional production capacity, it is safe to say that Zhanjiang Chenming PM 1 is the best paper machine in the world.
Jia Huadong, PM Deputy General Manager of Zhanjiang Chenming says: “We are very proud to have this world-class paper machine - the fastest in the world. We have a lot of Valmet’s new technology adapted in this new paper machine and with new technology we get more and better profit from the machine.
The OptiDry impingement dryer is the pearl of the machine. Without OptiDry the new world record speed would not have been possible.”
Mechanical Mill Manager Wang Zongzhou also comments on the new technology: “Implementation of new technologies is challenging for both parties and requires good cooperation. With the key Valmet persons, the communication was good and now we have this superior paper machine as proof of that cooperation.”
