REBUILD BY ANDRITZ GIVES SHANDONG HUATAI PAPER THE WORLD’S LARGEST MECHANICAL PULPING LINE
Shandong Huatai Paper has successfully started up a mechanical pulping line rebuilt by ANDRITZ at the mill in Dongying, Shandong Province, China.
ANDRITZ rebuilt the two high-consistency (HC) refiners and the screw presses, disc filters, and screens, and supplied new equipment for other process steps. The line now features the following technological highlights:
- New PrimeMSD Impressafiner for optimum wood chip maceration and chemical impregnation
- New Side-Entry Plug Feeder (SEPF) feeding system for constant and efficient HC refiner feeding
- New DCS system as a future-oriented control system for the new fiber line
- ANDRITZ Hydraulic Commander to improve the HC refiners’ operability and supply top-quality fiber with lower energy consumption
ANDRITZ also provided the basic engineering and supervised the mechanical installation, commissioning, and start-up.
The rebuild not only increased the line’s capacity from 100,000 t/a to 300,000 t/a, making it the world’s largest mechanical pulping line for printing and writing paper production. It also considerably reduced the line’s energy consumption and increased its pulp yield and quality.
