Stora Enso: Voith’s DuoShake improves formation on PM 6 in Oulu mill significantly

Thanks to the installation of a Voith DuoShake at the PM 6 of Stora Enso´s Oulu mill, Northern Finland, in August 2013 the Ambertec value was improved significantly for the production of paper with a basis weight of 250 g/m². Stora Enso places high quality demands on the paper grades produced in Oulu and wanted to improve the paper quality. After start-up and optimization of DuoShake, however, the expectations were exceeded by far.
Voith’s DuoShake improves Formation.
The Stora Enso mill in Oulu is one of the world's largest and most modern paper mills for the production of high-quality paper grades. PM 6 is equipped with a hybrid former and produces 620,000 t of wood-free coated paper per year on a wire width of 9.100 mm.

DuoShake is a reaction force-free shaking unit for the breast roll which ensures homogenous fibre distribution and improved CD fibre orientation, resulting in better formation, reduced MD/CD ratio and thus higher CD strength. Thanks to its compact design the DuoShake can easily be retrofitted to nearly any paper machine.
