MM Board & Paper, Austria, has successfully re-started its KM3 board machine at the Frohnleiten mill after ANDRITZ completed a major rebuild.

Mag. Gernot Schleiss, Managing Director of MM Frohnleiten, explains: "The main objective of our investment was the modernization of the KM3 to enhance the quality of the end product, to reduce specific energy consumption and to increase productivity across the entire product range. We are convinced that ANDRITZ's innovative PrimeLine technology will help us reach our targets." Georg-Michael Sautter, ANDRITZ Key Account Manager Paper Board adds: "The new PrimeFlow AT headbox improves the quality of the end product, the two PrimePress X shoe presses lead to energy and bulk savings, and the PrimeRun web stabilizers ensure improved runability. All in all, the perfect package for highly efficient and high-quality production."

KM3 has a design speed of 800 m/min and a wire width of 5 m. It produces folding boxboard (chromo duplex quality) with 230-450 gsm. The rebuild comprised the modernization of the wire section including approach flow systems, headboxes and hybrid former. In addition, ANDRITZ's scope included a new press section, the rebuild of the pre-dryer section, an upgrade of two under-machine pulpers, machine clothing and roll covers, adaption of the automation system, as well as assembly, start-up and production assistance.

MM Board & Paper is Europe's largest board producer (excl. liquid packaging board). With a capacity of 540,000 t/y, the mill in Frohnleiten, Austria, is Europe's largest recycled cartonboard mill.
