Apr 03, 2008. /Lesprom.com/. Metso Paper has received an order to rebuild the existing fiberline at the Sappi Austria Produktions-GmbH & Co. KG, Gratkorn Mill in Austria. The mill, producing fine paper mainly from spruce, is located 20 km from Graz. The start-up of the rebuilt fiberline is scheduled for April 2009. The rebuild is part of Sappi Gratkorn’s pulp mill upgrading project to decrease the energy consumption and to lower the maintenance costs. Two older wash lines with pressure filters for washing will be replaced with one modern wash line based on TwinRoll presses. Metso Paper's scope of delivery consists of screen room upgrade and new brown stock washing based on TwinRoll Press technology. The modernized line is designed for a daily production of 760 ODT/D (oven dry tonnes).
