Valmet’s supplied paper machine for Zhanjiang Chenming PM 1 is wide and large and is equipped with the very latest technology
Jul 25, 2018
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.
“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."
Jia Huadong, PM Deputy General Manager of Zhanjiang Chenming

The PM 1 features Valmet’s paper making and automation technology from headbox to reel, air and chemical systems and two winders. The machine's 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.
