Voith will supply the complete XcelLine process line from wet end process to winder, which it says will reduce the number of interfaces to a minimum and provides cost transparency for the entire project.

The order is the result of the long and successful cooperation between the companies to build the BM1 and BM3. Bohui Paper Group says its experts have already been impressed by the fast and smooth commissioning of these two machines in 2003 and 2013 respectively, adding that the subsequent efficient production process also ensured a high degree of customer satisfaction.

From December 2018, the new BM4 will operate at a speed of 1200 m/min to produce folding box board with a basis weight of 250 g/m2. The production line offers a range of special technical features that promise to improve the quality of the finished paper and reduce energy consumption. The wet section of the BM4 impresses with a new Clean Design concept that achieves particularly high runnability, the parties note. In the BM4, the use of a Triple NipcoFlex press not only ensures “tremendous dewatering” efficiency while preserving volume, but also achieves a smooth surface on the board.
