BillerudKorsnäs Orders New GL&V Equipment for Gruvön Board Mill

GL&V Sweden AB reports that BillerudKorsnäs Gruvön Mill, Sweden, has placed an order for 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 DD 6000 refiners will be equipped with the patented Anti-Plate Clash System, APCS, which detects and prevents refiner plate clashing..

The GL&V Refiner Plate Wear Indicator, an accurate laser-based system that measures the refiner plate wear, is also included in the scope of supply.

The Duflo technology is well known in the pulp and paper industry and in the Gruvön Mill specifically. The Duflo pump will take care of the big difference in flow as well as in consistency, which is common with the operation of a disc filter installed as a save-all/broke thickener. A key success for this is the efficient Duflo Impeller and the possibility to easily turn the internal vacuum system on and off.

Planned startup is scheduled for spring 2019.
