SCA Graphic Laakirchen AG, Laakirchen, Austria, reports that its PM 10 has successfully started up after a Metso-supplied press section rebuild. The main goal of the modernization was to increase production and decrease energy consumption.
"Our target was to increase sheet dryness after the third 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 on PM 10.
Metso, Finland, rebuilt the press section with a new SymBelt shoe press. In addition, its 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 speeds, 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 gsm at a design speed of 1,600 m/min. The production capacity of PM 10 is 260,000 metric tpy.
