GL&V Sweden refiner deflaker system to BillerudKorsnäs Gruvön

GL&V Sweden AB said that the BillerudKorsnäs Gruvön mill has ordered a complete refiner and deflaker system and a combined save-all/broke thickener together with DuFlo® pump technology for its new Board Machine, Next Generation project.

GL&V will deliver 13 DD®6000 refiners and three DF-20-2 deflakers for print-, middle- and back-ply. The energy efficient DD6000 refiners will have the patented anti-plate clash system, (APCS) which detects and prevents refiner plate clashing. GL&V s laser-based refiner plate wear indicator will be included.

The combined save-all/broke thickener and DuFlo pump will be the fifth Celleco® Centerdisc® CDI disc filter for the BillerudKorsnäs group. The unique, strong design of the CDI filter makes it perfect for this type of application, says GL&V. The ability to combine the saveall and broke thickening applications saves the need for a separate broke thickener filter. The CDI filter will have stainless steel covers to improve runnability and reduce maintenance costs.

The DuFlo technology is well known in the pulp and paper industry and in the Gruvön mill particularly. The DuFlo pump will take care of the big difference in both flow and consistency which is common when operating a disc filter as a save-all/broke thickener. A key reason for this is the efficient DuFlo Impeller and the possibility of turning the internal vacuum system on and off. Planned start-up is scheduled to spring 2019.
