Metso's delivery will include a SuperBatch cooking plant and fiberline equipment for screening, brown stock washing, oxygen delignification, post oxygen washing and bleaching as well as basic engineering, supervision and spare parts. The brown stock washing in the line will be performed on TwinRoll wash presses and washing after each bleaching stage on vacuum filters.
The new fiberline is an important investment for the Yunnan Yun-Jing mill for ensuring high-quality and environmentally beneficial operation. Processes and equipment delivered by Metso provide sustainable production with a low use of chemicals, water and electricity.
Yunnan Yun-Jing Forestry and Pulp Mill CO., Ltd's first production line was built in 1995.
