Supplier: Andritz

Description: Andritz will relocate and upgrade a fiberline for Yueyang Forest & Paper to produce premium quality fibers for its new paper machine. The P-RC APMP (Pre-Conditioning Refiner Chemical Alkaline Peroxide Mechanical Pulp) line was originally supplied by Andritz in 2011 to the mill in Yuanjiang city, Hunan province. Andritz will now transfer it to Yueyang city, Hunan province, where it will process mixed hardwood for the production of printing and writing papers.

By adding new high-efficiency equipment and refurbishing existing machines, the upgrade will raise the line’s minimum design capacity to 650 admt/d and improve fiber quality while saving energy and chemicals.

Details: Mr. Xu Jianhong, Project Manager of Chemi-mechanical Pulp Lines’ Reform Department, Yueyang Forest & Paper, says: “Andritz successfully completed a similar relocation and modernization project for us in 2018. Their extensive experience, proven technology for mechanical pulping, and highly professional service team were decisive factors why we chose Andritz again as our partner for this project.”

Andritz will modernize the line by adding a second stage impregnation and a second bleaching system. A PrimeMSD Impressafiner will ensure efficient pre-treatment and optimum chemical impregnation of the wood chips to improve fiber quality at reduced energy and chemicals consumption. In addition, Andritz will rebuild two existing HC refiners, upgrade a sealing system and refurbish three screw presses and two pressure screens used in a former DIP line. This will significantly reduce investment costs while meeting all technological requirements. Andritz will also provide the supervision of installation, commissioning, start-up, and training.

Start up: Start-up is scheduled for the second half of 2024.
