2025/01/23

International technology group ANDRITZ has received an order from Sun Paper Nanning Paper Co., Ltd to supply two stock preparation systems and a complete P-RC APMP (Pre-Conditioning Refiner Chemical Alkaline Peroxide Mechanical Pulp) line for the mill in Nanning, China.

Start-up is scheduled for the third quarter of 2025.

The new equipment will enable Nanning Sun Paper to increase production of their paper production lines and to reduce energy consumption.

ANDRITZ’s scope of supply includes two state-of-the-art stock preparation, paper machine approach, UTM (under machine pulper), and broke systems to provide superior pulp for the two paper machines. PM11 produces high-quality testliner with a maximum capacity of 1,438 admt/d, while PM12 produces high-grade offset paper with a maximum capacity of 1,100 admt/d.

The P-RC APMP line, the seventh ANDRITZ is supplying to Sun Paper, will have the capacity to process 450 admt/d of eucalyptus to provide high-quality pulp for the production of premium printing and writing paper. ANDRITZ will supply core equipment from the silo discharger to wood chip impregnation, bleaching, LC refining, screening, and rejects treatment. The scope of supply also includes:

  • PrimeMSD Impressafiner for efficient wood chip pre-treatment and optimal chemical impregnation, effectively reducing energy and chemical consumption in the high-consistency refining stage
  • Eight sets of newly developed TwinFlo Prime refiners for user-friendly operation and high efficiency in reducing both freeness and shive content, with minimum maintenance requirements
  • PrimeScreen X for high screening efficiency while significantly reducing energy consumption

ANDRITZ will also provide installation supervision, commissioning, training, and start-up assistance.

Mr. Ying Guangdong, Deputy General Manager and Chief Engineer of Sun Paper Group says, “Based on our long-standing partnership, we have full confidence in ANDRITZ's commitment to deliver high-performance, reliable, and energy-efficient technological solutions.”
