Metso-supplied Ningbo APP board machine sets new production and speed records

The world's largest paper and board production line, the Ningbo Asia Pulp & Paper PM 6 in Xiaogang, Ningbo city in Zhejiang province, China, repeatedly sets new production and speed records. In April, this year, the machine once again broke its own world production record by producing 3,500 t/day of 350 g/m2 art board in 24 hours.

The PM 6 has set a new world speed record as well. The board machine ran at a speed of 950 m/min for a period of 24 hours, producing art board with a basis weight of 300 g/m2. The speed record was set on June 3, 2008, during normal production running.

The line’s previous world records from November, last year, were 3,110 t/day and 900 m/min.

The 410-m-long Ningbo Xiaogang PM 6, which was started up in November 2004, produces high-quality Duplex and Triplex grades of white lined chipboard (WLC) and art board in the basis weight range of 250 to 450 g/m2. The line has a trim width of 8.1 m and a design speed of 900 m/min. Supplied by Metso Paper, the line consists of a complete eight-line stock preparation system for both virgin and recycled fiber, and a complete five-ply board machine including a five-station on-line coater.
