|Location||PowerFlute operated paper Mill at Savon Sellu in Kuopio, Finland|
|Customer challenge||Too low capacity, old equipment that had reached it's end of a lifecycle.|
|Solution||Low energy, two stage, low consistency refining process that optimizes the stiffness values (CMT and CCT). The second refining stage has two new OptiFiner Pro refiners for high capacity. Old refiners equipped with new refiner segments were moved to the first stage. Additionally, a new OptiFiner Conflo refiner was installed to the first stage.|
|Results||More accurately controlled refining process, up to 30% less energy while achieving the same freeness value as before, lower maintenance costs.|
