World’s most modern board machine successfully commissioned at BillerudKorsnäs in Gruvön
- New performance benchmarks in board production
- Cutting-edge technologies and smart digital solutions
- Features other innovations like highly specialized coating units and use of carbon fiber components
State-of-the-art: outstanding technological features
Some of the standout features of the former section include a three-ply wire section with a DuoFormer D II hybrid former, two state-of-the-art DuoShake shakers and a fiber orientation control system. The scope of supply also includes various MasterJet Pro F systems with additional IntraDamp modules for the headbox. In the press section, a Tandem NipcoFlex shoe press with SolarPress roll covers ensures optimum dewatering.
In the dryer section, EvoDry steel cylinders are being used in a board machine for the first time. The special cylinders allow highly efficient and safe paper drying thanks to higher heat transfer and greater working width. Another first at a European paper mill is the high performance winder VariFlex XL.
In the finishing section, the BM 7 is also the first board machine worldwide to be fitted with Curl Control. For maximum flexibility and optimum product quality, the machine also has four different coating units: two SpeedSizer systems, one JetFlow F and one DynaCoat AT. Both the SpeedSizer units and the DynaCoat AT have carbon fiber supporting structures to ensure stable CD profiles with consistent coating performance.
Papermaking Next Level: integrative digital solutions
The Papermaking 4.0 solutions OnEfficiency and OnCare, which allow all process data to be monitored and controlled online in a user-friendly format, are also major components of the BM 7. Among other things, OnEfficiency Forming enables de-watering, retention and flocculation to be stabilized and coordinated at the same time. The OnCare package including integrated asset management ensures maximum machine availability thanks to highly efficient preventive maintenance of the entire paper machine. This in turn also helps reduce project costs.
Initial clothing of BM 7 by Voith
Voith was engaged to supply the initial clothing for the BM 7. In addition, as main supplier for the BillerudKorsnäs mill, Voith will over the next three years supply the CleanWeave dryer fabrics, Kinetic and Infinity press felts and I-Series forming fabrics. This will ensure consistently high paper quality and is yet further evidence of the customer’s trust in Voith and confirmation of Voith’s success as a full-line supplier.
