Rebuild increases production by 10% at Stora Enso Sachsen
After Voith carried out a rebuild of the Eilenburg PM 1 at Stora Enso Sach-sen, Germany, the paper machine was successfully started up again in May 2012. The aims of Stora Enso were to improve runability and to elimi-nate existing bottlenecks in the system. Furthermore, the maximum operat-ing speed of the paper machine was increased to 2,000 m/min, corre-sponding to a production increase of about 10% (depending on the grade range). Already one month after rebuild, the operation speed exceeded 1,900 m/min.
With the rebuild a new NipcoFlex press module was installed, which has increased the dryness content after the press by 3-4% after just a short time. In addition, a new exhaust system in the wet end and a JetCleaner for cleaning the bottom wire provide for more cleanliness and thus im-proved runability. The old calender was replaced by a Janus calender so as to increase the paper quality. The project also included a rebuild of the dryer section together with fabric stretchers, fabric guides and the machine air ventilation system. A new trim cutter and a new threading system com-pleted the scope of supply.
