The PM 6 start-up was successful with record-breaking results. “The whole start-up was perfect. It took less than three hours in total from having stock on the machine to get the web on the reel, and we had a very good start-up speed of 800 min/min. No paper tails were seen on the hall floor during the start-up period,” Xue Rong Jun, Project Manager of Fujian Liansheng, proudly says.

The new 7.25-m-wide PM 6 production line has an annual production capacity of approximately 300,000 tonnes of recycled fluting in the basis weight range of 65 to 100 g/m2. The design speed is 1,200 m/min. Metso’s delivery included a complete OptiConcept M boardmaking line from headbox to reel with air systems, a machine control system, a quality control system, two winders and Metso clothing.

The PM 6 OptiConcept M production line is designed for high productivity with low operating costs. Industrial design and new engineering innovations provide for simple assembly of the production line. “The installation required 30 to 40% less working hours compared with a conventional project,” comments Xue Rong Jun.
