First fibers produced with the world’s largest pressurized refining system

Guangxi Chongzuo Lelin Forestry Development Co. Ltd., China, has successfully produced the first fibers with its high-capacity pressurized refining system delivered by Andritz. The new system features a design capacity of 80 bdmt/h and is currently, according to Andritz, the largest of its kind in the world to form part of the largest MDF line.

Andritz installed the complete system, from chip washing to refining. It comprises a 74” single-disc refiner with the largest flat refining surface available and highest axial load capacity ever built. With an impressive height of nearly 2.4 meters and a total weight (empty) of 21.7 tons, the HC refiner, type S2074M, is a real giant – built for outstanding production rates.

Wei Rengang, General Manager, Guangxi Chongzuo Lelin Forestry Development, says: “The entire line, and especially our new HC refiner is really impressive – not only because of its dimensions. It has already shown very promising performance. Our thanks go to Andritz for their hard work and the exceptionally good collaboration.”

Guangxi Chongzuo Lelin Forestry Development Co. Ltd. is part of the Lelin Group, headquartered in Nanning, Guangxi, which has been focusing on wood-based panel production for nearly 20 years. In addition to two biomass power plants, the company owns four wood-based panel manufacturing enterprises and will have an annual fiberboard output of 1,300,000 m3 after the new line is completed. The Guangxi Lelin Group is well-known for its high-quality products, ranging from door panels, engraving and milling panels to formaldehyde-free board and furniture board.
