Andritz to convert PM for Burgo Avezzano, Italy

Graz, Austria-based Andritz has an order from the Italian Burgo Group to rebuild and convert its PM2 from producing printing and white writing paper to a modern brown packaging paper machine at the Avezzano mill, Italy. The conversion will put Burgo in the packaging business which is part of its diversification strategy.

The new PM 2 will have a capacity of over 200 kt/, a design speed of 1200 m/min and a paper width at reel of 5340 mm. The machine will use recycled OCC and mixed waste paper to produce corrugating medium and two-ply testliner with a basis weight range of 80-170 g/m2 for the production of containerboard. Start-up is scheduled for the end of 2017.

A 700-bdt/d stock preparation line will comprise a pulping system with FiberSolve FSR pulper, cleaning, screening, fractionation, thickening and reject handling. The approach flow system will be rebuilt and a ShortFlow deaeration system installed.

Also included is a new PrimeFlow SW headbox for the top-ply and a new PrimeForm SW top former, as well as elongation of the bottom Fourdrinier. The pre- and after-dryer sections will be equipped with PrimeRun web stabilizers for the single- and double-tier dryer groups to optimize machine runnability. A PrimeAir Glide air turn will be installed after the existing film press. To reach the maximum drying capacity needed, 10 PrimeDry Steel cylinders will be added to extend the after-dryer section.

The order includes basic engineering, erection supervision, start-up, commissioning and training.
