In a press release by Andritz, Guangxi Chongzuo Lelin Forestry Development has successfully produced the first fibres with its high-capacity pressurised refining system delivered by Andritz.

The new system features a design capacity of 80 bone dry metric tonne per hour, and is reportedly “the largest of its kind in the world” now to form part of “the largest medium-density fibreboard (MDF) line”.

Andritz installed the complete system, from chip washing to refining. It comprises a 74-inch single-disc refiner with a large flat refining surface and a high axial load capacity. With a height of nearly 2.4m and a total weight of 21.7 tonnes, the high-capacity refiner, type S2074M, is built for optimal production rates.

Wei Rengang, general manager of Guangxi Chongzuo Lelin Forestry Development, said: “The entire line, and especially our new high-capacity 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 is part of the Lelin Group, headquartered in Nanning, Guangxi, China, 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 1.3 million m3 after the new line is completed.
