Cartiere del Polesine orders screening systems for Adria OCC line
I
talian containerboard manufacturer Cartiere del Polesine is having the existing OCC line
at its mill at Adria rebuilt by Andritz.
In addition to all main process
components, Andritz will also install newly-developed equipment for primary-stage fine screening as well as fractionation. The fluting and testliner
production line will have a capacity of 400 bdmt/d and process AOCC (American old corrugated container) as well as special waxed waste paper as raw material when it starts up in the first quarter of 2020. A FibreFlow drum pulper with
extended pulping and screening section will slush the difficult- to-handle raw material to ensure gentle pulping, high fibre yield, and reliable operation. Specific trials on the industrial- scale drum pulper at the
PrimeScreen Xs will be part of the screening processes. The innovative top-feed
Andritz Stock Preparation Pilot Plant in Graz, Austria, confirmed future pulp properties and operating
characteristics in advance. Different types of ModuScreen
pressure screens as well as two next-generation
New tissue maker in Romania orders lines from Andritz
Newly-formed Romanian tissue maker MG TEC Industry has ordered two complete tissue making lines from Andritz. The order for a mill at Dej
comprises two PrimeLineCompact V tissue machines with steel Yankee dryers along with complete stock preparation systems, pumps, automation, hall ventilation, and electrification. Start up for the TM1 line is planned for 2020 with the TM2 line starting up two years later.
Each line will be equipped with a stock preparation system including approach flow system and broke handling. The proven TwinFlo disc refiner technology is used in a separate long- fibre line to achieve optimum development of fibre properties. The approach flow systems feature the ShortFlow concept, which allows a minimised number of equipment items and very low storage volume as well as fast grade changes at the
tissue machine.
The tissue machines have a design speed of 1,900 m/ min and a width of 2,850mm, and are equipped with 15ft PrimeDry Steel Yankees. The drying components for each line comprise a PrimeDry Hood G, a PrimeDustEXT dust extraction system, and a PrimeMistEXT mist extraction system as well as the hall ventilation system and will be delivered by Andritz Novimpianti. The pumps, with efficiencies
of up to 90 per cent, enable long life cycles at highest cost- effectiveness. An automation system combined with the latest drive technology ensures modern and efficient plant operation. MG TEC project coordinator Ioan Tecar commented: “Decisive criteria for the order were the innovative technologies of Andritz that enable easy and safe operation with high quality and the capability to deliver everything from a single source.”
July/August 2019
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 minimise 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.
