The first line delivery from Metso Paper and its joint venture company Valmet-Xian to Dongguan Jianhui Paper Co, Ltd was successfully started up in late May of 2004. BM1 produces high-quality coated White Lined Chipboard (WLC) at an annual rate of over 300,000 tons per year. The machine produced saleable paper only a few days after the start-up. Commissioning and start-up was short and easy thanks to the one supplier seamless co-operation between all parties, Dongguan Jianhui, Metso Paper and Valmet-Xian.
The four-layer, on-machine coated board machine has a wire width of 4.95 m and a design speed of 700 m/min. Metso Paper's delivery to Jianhui included all the key components while the base machine was delivered by Valmet-Xian. Metso Paper's scope includes 4 SymFlo headboxes, one of which is dilution controlled for improved profiles, and a SymFormer MB unit, which is installed in the filler ply to improve dewatering capacity and formation. In the press section a SymBelt shoe press was installed to improve dryness and bulk. Surface sizing is done with a ValSizer. The on-line coating section includes an OptiHard calender, four ValCoat applicator roll stations, and an OptiSoft calender.
Metso Automation has delivered IQDilution Lite actuators for SymFlo D headbox, IQWeightCD control system for profiling and the PaperIQ quality management system.
