Five-stage cleaner system for the new PM3


due to the preliminary tests carried out at the Andritz Stock Preparation Pilot Plant in Graz. This raises the general questions of how PM3 has performed in the first five months of operation and expectations for the future. “We haven’t completed all of


the performance tests yet, but our experience has been very positive so far,” says Jürgen Rieger, chief operations manager at Zellstoff Pöls AG. “The start-up phase was impressive. Operation is very stable, and the paper grades with basis weights between 20 and 52


With its industrial companies Zellstoff Pöls and Laakirchen Papier (Austria) as well as Raubling Papier (Germany) and Estonian Cell (Estonia), the Heinzel Group is one of the largest manufacturers of market pulp, speciality and magazine paper, and corrugated base paper in Central and Eastern Europe.

g/sqm were produced successfully. We are optimistic that the machine will also run well under full load.” Nevertheless, this is by no means the end of the story. In Pöls, there are a number of considerations as to how paper production can be further optimised, for example, by increasing use of digitally supported tools, ‘big data’, algorithms, and machine learning. Andritz offers its Metris solutions as a partner, especially as these products are already being used in the stock preparation plant at Pöls. In papermaking, they could also increase efficiency by using sensors to collect and


generated annual sales of around €324 million in 2018. It is the largest manufacturer of high- grade, elemental chlorine- free, bleached, long-fibre sulphate pulp in Central and south eastern Europe. Pulp is brought to market with the brand name ‘Orion’, white kraft paper is sold under the brand name ‘Starkraft’.


Key components in stock preparation:


● Vertical Screw Thickener (VST)


● FibreSolve FSV pulper ● Five TwinFlo disc refiners ● Five-stage cleaner system ● Five ModuScreen screens in stock preparation and ShortFlow approach flow system


statistically analyse real-time process variables in order to initiate additional improvements directly in operation. Without a doubt, the PM3 marks a milestone for Pöls.
