ANDRITZ rebuild 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. 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. 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
