“Our target was to increase sheet dryness after the 3rd press for increased speed. We also wanted to reduce the draw and specific energy consumption and at the same time maintain the high quality level as before the rebuild,” says Andreas Vogel, production manager of SCA Graphic Laakirchen PM 10.

Metso’s delivery comprised a rebuild of the press section with a new SymBelt shoe press. In addition, the delivery included mechanical drives for the whole press section and an automation system upgrade for the shoe press. The SymBelt shoe press significantly increases sheet dryness which in turn reduces steam consumption, improves machine runnability, helps reach higher speed and increases production.

The 7.3-m-wide PM 10 produces uncoated wood-containing paper (SC-A) within a basis weight range of 45-60 g/m² at the design speed of 1,600 m/min. The production capacity of PM 10 is 260,000 t/y.
