The Arne Asplund Award

Bengt Åkerblom wins the Arne Asplund Mechanical Pulping Award 2020
We are delighted to announce that the founder of our company, Bengt Åkerblom, was the proud recipient of the Arne Asplund Mechanical Pulping Award 2020.

Taken from Valmet’s website:
The way in which Bengt Åkerblom has developed the True Disc Clearance (TDC) and Adjustable Gap Sensor (AGS) for chip and pulp refiners has enabled tremendous improvements to be made in both the availability and control of refiners, thereby increasing pulp quality and reducing specific energy consumption. These sensors are installed in the vast majority of high-consistency mechanical pulp refiners around the world. Lately, his work has enabled the development and usage of refining processes based on feeding refiner segments. Such systems, in which the very accurate control of extremely small refiner gaps is fundamental, allow significant specific energy reductions to be made.
