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.
