International technology Group ANDRITZ has received an order from Cartiere del Polesine to rebuild an existing OCC line including reject treatment at the mill in Adria, Italy. In addition to all main process components, ANDRITZ will also install two newly developed PrimeScreens X for primary-stage fine screening as well as fractionation. Start-up is scheduled for the first quarter of 2020.

The fluting and testliner production line will have a line capacity of 400 bdmt/d and process AOCC (American Old Corrugated Container) as well as special waxed waste paper as raw material.

An ANDRITZ FibreFlow drum pulper with extended pulping and screening section will slush the difficult-to-handle raw material in order to ensure gentle pulping, high fiber yield, and reliable operation. Specific trials on the industrial-scale drum pulper at the ANDRITZ Stock Preparation Pilot Plant in Graz, Austria, confirmed future pulp properties and operating characteristics in advance.

Different types of ANDRITZ ModuScreen pressure screens as well as two next-generation PrimeScreens X will be part of the screening processes. The innovative top-feed concept of the new screen was decisive for Cartiere del Polesine to order ANDRITZ’s new screening technology. The top-down design takes advantage of gravity to remove heavy contaminants quickly and minimize wear on rotor and screen basket. Top-down also improves the removal of light rejects, preventing their accumulation in the feed area, which again extends the life of wearing components.

The scope of supply also includes reject treatment, basic engineering and site services.

Cartiere del Polesine is a major player in the Italian and European containerboard industries and focuses on sustainable and innovative production. Four paper machines in two different mills produce around 300,000 tons of containerboard per year.

International technology Group ANDRITZ has successfully started up the latest innovation in dewatering – the Vertical Screw Thickener (VST) – at Zellstoff Pöls AG, Austria. The VST has been operating successfully since the beginning of December 2018 and supplying the existing MG paper production line PM2 with the maximum capacity of 360 t/d.

The pioneering Vertical Screw Thickener is a screw press with a vertical configuration and a very small footprint, making it suitable for retrofit installations in existing buildings. The pulp suspension is fed into the top of the machine, and its downward transport is gravity-assisted. At Zellstoff Pöls, the VST is located just before the finished pulp storage tank that feeds the paper production line and thus enables separation of the pulp mill and paper machine water loops.

ANDRITZ Vertical Screw Thickener manufactured in Graz, Austria.ANDRITZ Vertical Screw Thickener manufactured in Graz, Austria.

The VST dewaters the pulp suspension from 3% inlet to 25-30% outlet consistency, and the water removed is recycled and re-used in the pulp mill. The ability to dewater from low-consistency inlet to high-consistency discharge is an important advantage compared to conventional dewatering equipment: Paper machine water is added to the dilution conveyor after the VST. Separation of the water loops results in savings in paper additives (e.g. sizing agent) at the paper machine. The VST replaces an existing gravity table at Zellstoff Pöls and feeds the MG paper production line for PM2.

Jürgen Rieger, Chief Operations Manager at Zellstoff Pöls, points out: “Our expectations of the new Vertical Screw Thickener were more than fulfilled. After the fast and trouble-free start-up, we are now already seeing the positive effects, like reduction of sizing agent consumption.” Patrick Wohlmuth, Process Technology Manager at Zellstoff Pöls, continues: “The results of our previous tests in the ANDRITZ Stock Preparation Pilot Plant were perfectly implemented in our mill-site production process with the VST 1005.”
