Andritz has received an order from Nine Dragons Paper Industries to supply two chemi-thermomechanical pulping systems for their mills in China. The start-ups are scheduled for spring and summer 2022.

Andritz will install its well-proven P-RC APMP (pre-conditioning refiner chemical alkaline peroxide mechanical pulp) technology to ensure optimum pulp quality at lowest energy consumption and highest availability. The fiberlines will have a capacity of 1,000 admt/d and 670 admt/d, respectively, and will process a mixture of eucalyptus, acacia and poplar wood chips for the production of folding boxboard (FBB).

Andritz will supply the main equipment - from chip washing to the storage tower - for both fiberlines, featuring the following highlights:
- MSD Impressafiner for wood chip maceration to enable optimum chemical impregnation.

- High-consistency (HC) refining stage with TX68 refiner, including an advanced feeding system for optimum fiber development and lowest shive levels.

- Low-consistency (LC) refining stages with TwinFlo refiners for low specific energy consumption and well-developed fibers.

- Four newly developed PrimeFilter D disc filters for fiber recovery and thickening. The innovative disc filters feature the so-called HHw (high consistency, high freeness, wider space between discs) technology for advanced feeding and optimum flow conditions within the filter as well as CC bagless sectors for advanced operation and reduced maintenance.

The scope of supply also includes the basic engineering as well as supervision of mechanical installation, commissioning and start-up.

Nine Dragons Paper is part of the Nine Dragons Paper Group, an important global player in the pulp and paper industry with mills in China, Vietnam, Malaysia, and the United States.
