International technology group Andritz has successfully started up a newly converted stock preparation system at Heinzelpaper Laakirchen, Austria.
This significant upgrade represents a key transition for the PM11 paper machine, which will now produce high-quality packaging board from 100% recycled wastepaper.
The conversion process involved transforming the stock preparation system from a deinked pulp line to an old corrugated containers (OCC) line. Heinzelpaper Laakirchen chose a combination of the Andritz FibreFlow drum Prime (FFD) for pulping and Andritz ADuro shredders for reject treatment. This innovative setup ensures superior fiber quality for the company´s high-end products while optimizing resource usage and reducing waste.
Andritz's scope of supply included the FFD, key equipment for screening, cleaning, and reject handling, as well as the rebuild of certain individual components. Additionally, Andritz provided comprehensive engineering services, supervision of the erection process, the start-up, and training.
The FFD pulper, with a feed capacity of up to 2,000 admt/d, is now the largest Andritz FFD in operation in Europe. The integrated recycled fiber (RCF) line, in combination with the FFD 450, can produce an impressive 1,600 tons of high-quality fiber per day, setting a new benchmark for efficiency and sustainability in fiber production.
Heinzelpaper comprises the mills Laakirchen and Steyrermühl in Upper Austria. The Laakirchen mill specializes in the production of environmentally friendly, lightweight corrugated base paper based on recycled paper for the European market.
Andritz Pulp & Paper provides sustainable technology, automation, and service solutions for the production of all types of pulp, paper, board and tissue.
