Andritz to supply sixth P-RC APMP system for Sun Paper

According to Andritz, this will be the sixth P-RC APMP (Pre-Conditioning Refiner Chemical Alkaline Peroxide Mechanical Pulp) line for Sun Paper and part of the new greenfield paper mill in Beihai. The new fiber line will process eucalyptus woodchips as raw material and features a capacity of 600 admt/d.

Guangxi Sun Paper was established in July 2019 to build an integrated greenfield pulp and paper mill in Beihai, Guangxi. The mill will be constructed in two phases over approximately five years. When fully completed, it will have a total annual pulp and paper capacity of 3.5 million tonnes.

The excellent performance by the five P-RC APMP systems operating in our Yanzhou mill convinced us to trust once more in Andritz. Their impregnation technology, in particular, with the MSD Impressafiner will enable us to produce excellent mechanical pulp quality again, which will be an essential precondition for our production of printing, writing, and culture paper here in Beihai, said Ying Guangdong, Vice General Manager and Chief Engineer at Sun Paper.

The scope of supply, the value of which has not been disclosed, comprises all main equipment from chip washing to pulp storage. Andritz will also supply basic engineering and training and provide support in mechanical installation, commissioning, and start-up.

The P-RC APMP system features the following technological highlights:

• MSD Impressafiner for woodchip maceration to enable optimum chemical impregnation;
• High-consistency (HC) refining stage with two parallel Andritz S2070 single-disc refiners for superior fiber properties and highest production flexibility;
• Low-consistency (LC) refining stage with six Andritz TwinFlo refiners to develop optimal pulp strength and lowest shive content.
