Liansheng Paper Industry Co., China, has started up a new Metso-supplied containerboard production line, PM 6, at its Longhai site in the Fujian Province of China. This is the first startup of Metso's OptiConcept M production line that "represents a new way to design, build, and operate a paper machine."
The PM 6 startup was successful with record-breaking results. "The whole startup was perfect. It took less than three hours in total from having stock on the machine to getting the web on the reel, and we had a very good startup speed of 800 m/min. No paper tails were seen on the hall floor during the startup period," Xue Rong Jun, project manager of Fujian Liansheng, said.
The new 7.25-m-wide PM 6 production line has an annual production capacity of approximately 300,000 metric tons of recycled fluting in the basis weight range of 65 to 100 gsm. 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," Jun reported.
Also, usability and safety aspects are at a new level. For instance, the design allows for easy, fast, and safe changing of wear parts, which reduces the duration and costs of maintenance shutdowns, Fujian Liansheng explained. "The design of walkways is very ergonomic, spacious. Walkways are on one level, no running up and down stairs, so the machine is very safe and convenient to operate and maintain. Since there are no cantilevering beams at the wet end, the drive side and tending side are symmetric, and the machine drive side is very spacious compared with a traditional machine construction," Jun said.
