The rebuild 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.
