Andritz has successfully completed the start-up of PM2’s dryer section at Smurfit Kappa’s Hoya mill, Germany. As a result, Smurfit Kappa – one of the leading producers of paper-based packaging in the world with more than 41,000 employees in 32 countries, can achieve its goals to increase capacity, improve product quality, and reduce energy consumption.
The rebuild of the test liner and fluting machine comprised the following Andritz performance:
■ Complete dismantling of the dryer section and rebuild with new frame and new rolls, supply of a PrimeRun web stabilization system, ropeless tail-threading (PrimeFeeder), a film press (PrimeCoat Film), and a new energy-recovery hood. In spite of the average paper weight being reduced, the capacity could thus be increased by 17%, formation improved, and energy consumption significantly reduced.
■ In a second rebuild phase, the machine’s output was increased again by 17%. In order to achieve this goal, Andritz Pulp & Paper moved the complete reel and enlarged the after-drying section by adding a PrimeDry ST and a PrimeDry DT dryer section, as well as a PrimeRun web stabilization system. The new components have a design speed of 1,200 m/min, at a width at reel of 7,600 mm.
