High-quality fibre is perfect for top layer
Until the end of 2015, Dongguan Jianhui Paper imported virgin fibre to produce the top layer of its high-quality coated board products. Today, recycled fibre has been substituted for costly virgin fibre thanks to a new three-loop deinking plant supplied by ANDRITZ. The lower-cost fibre meets all expectations of customers and mill management. PPL reports
“T
his was good timing for such an investment,” says Li Guihua, chairman and general manager
of Dongguan Jianhui Paper when referring to the €13.8 million his company put into a new deinked pulp (DIP) production line. “Even though it was made to enhance our competitiveness and lower our overall cost, we had also the advantage of our currency against the Euro.” Dongguan is a major industrial city at the Pearl River Delta in Southern China. Dongguan Jianhui Paper is a rather new company, established in 2002. The mill site is strategically located in the midst of convenient water sources and a good land transportation network. First production of coated board products began in 2004. A second machine followed in 2005. Development has been fast. After some upgrades, capacity surpassed 800,000 tonnes per annum. The installation of a third 600,000 t/a line boosted total capacity to 1.4 million t/a.
Top quality, high standards According to Mr Li, his company’s capacity for the production of coated board ranks second in the Pearl River Delta, and very high in the whole country. “Most important, our quality ranks at the top, if not the very best,” he says. Dongguan Jianhui Paper

The company has been chosen as an enterprise with National Quality Level ‘A’ trust. With quality certain, Dongguan Jianhui Paper set its sights on optimizing costs. A major cost factor was the import of virgin fibre for the top layer, fibre imported from Indonesia, Canada, and Brazil. In technical discussions,
representatives from ANDRITZ
showed the results of mills using 3-loop DIP systems to produce pulp that achieved the brightness and quality needed for top layer production. The ANDRITZ 3-loop system – including drum pulping, three flotation stages, two dispersing stages, screening/ cleaning systems, and sludge handling – is state-of-the-art. Due to the high quality standards
at the mill, choosing the right supplier for a DIP system was a careful and meticulous process. The expectation was to get good quality stock with the most economical fibre, and also to lower energy consumption and fresh water consumption. “As
DIP references in China and around the world, and nine 3-loop systems in China – far more than any other supplier. One important reference in China, was a 3-loop DIP plant with 550 t/d capacity producing pulp for a new LWC machine. “Andritz has the most complete and advanced deinking system in the world,” Mr Li says. “They not only offer a competitive price, but also good quality and a package of services that we considered as being the most superior.
