Liansheng Pulp & Paper reaches record high daily BCTMP production
In January 2025, a delegation from Valmet visited Liansheng Pulp & Paper’s Zhangzhou mill for in-depth discussions, reinforcing the strong collaboration between the two companies. At the same time, the two BCTMP production lines in phase 1 of the Liansheng Zhangzhou project were awarded for record high daily production.

Cooperation to create new heights
The exchange meeting was held in the conference room of the office building of Liansheng Zhangzhou. During the exchange, Xue Rongjun, General Manager of Liansheng Pulp & Paper said that the integrated development of pulp and paper in Zhangzhou is steadily advancing, and the pulp and paper balance of the mill is taking shape.
“At present, Liansheng's self-produced pulp has basically achieved full production, and it has been added to the production of cardboard, cultural paper and toilet paper to a great extent. The construction of the second phase of the BCTMP line and white cardboard machine project is also progressing in an orderly manner. Special thanks to Valmet for its comprehensive support and cooperation in terms of timely delivery, cooperation at the installation site, and availability of start-up experts,” Xue Rongjun added.
Subsequently, the awarding ceremony was carried out in the office of the workshop, and Liu Jingwei and Wang Zhenhua from Valmet presented the BCTMP team with the inscription; Strive to be the first. The double production line is the world's best with stable and smooth operation, low consumption, high efficiency and excellent quality.
"The new record was made possible not only by the excellent reliability of Valmet's BCTMP technology, but also by the collaboration between both teams. Of course, this achievement is also a testament to the meticulous management, precise operation, and determination to overcome challenges demonstrated by the Zhangzhou BCTMP team,” says Zhang Bin, BCTMP mill manager.

High yield, low consumption, and outstanding pulp quality
"At present, the production of our two lines in the first phase can be said to be the largest domestic and even international single-line machine for pulp production. The quality of the pulp fully meets the needs of the paper machine. Given that the current slurry consumption is below the maximum capacity, we usually arrange one line to run at high production and the other line to flexibly adjust production according to the actual demand to ensure optimal production efficiency and resource utilization,” Zhang Bin elaborated.
During the exchange, Zhang Bin spoke highly of the stable operation of Valmet's TwinRoll presses. In addition, Valmet's grinding discs have a proven service life: more than 2.5 months for high-consistency grinding and more than 5.5 months for low-consistency grinding.
Regarding the two existing lines and the two BCTMP lines under construction, Zhang Bin adds "We have just placed an order with Valmet for the HT CTMP-system. I am confident that the introduction of HT technology will further improve the quality of the finished pulp, not only in terms of bulk thickness, but also in terms of power consumption.”

Creating more opportunities
In the first phase of the Liansheng Zhangzhou project, Valmet delivered an all-in-one solution. With the advancement of the second phase of the project, Valmet will continue to uphold the customer-centric concept and deepen the strategic cooperation. This will help Liansheng achieve greater breakthroughs in the integrated development of pulp and paper and create more opportunities in future markets.
