Shandong Huatai Paper has successfully started up a mechanical pulping line rebuilt by ANDRITZ at the mill in Dongying, Shandong Province, China. 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.

Wei Lijun, Director of Shandong Huatai Paper, says: “Thanks to the close cooperation between the teams of ANDRITZ and Shandong Huatai, we were able to start up the rebuilt line as scheduled. We are delighted about the massive increase in capacity as well as the additional benefits of the modernization. Energy consumption has dropped by about 15% and pulp quality has greatly improved. The amount of fiber shives has also gone down significantly. As a result, we are able to cut back on imported chemi-mechanical pulp in our raw material structure, which lowers costs and supports our environmental performance.”

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 fiberline
  • 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.
