approximately 20 per cent. The new Andritz ModuScreen A44 in the fine screening plant has achieved excellent screening as a result of the special screen basket/rotor concept. The new Bar-Tec rejector screen baskets used in coarse screening (slot width 0.4 mm) with patented bar profile achieve better removal of impurities compared to the perforated screen baskets used so far and feature low energy consumption. In order to secure the energy


savings of more than 20 per cent as agreed in the contract, a few optimisations were needed first, but were completed quickly. “There are always small snags in


any project. But everything was resolved very well overall,” says Leipa project manager Gerhard Laue, confirming the satisfactory completion of the project. “At last, we no longer have to think about screening any more after this rebuild – that is certainly the biggest compliment for Andritz as supplier. “Just like the screw press


rebuild in 2013, this optimisation demonstrated that changes to individual units or sub-systems influence the ecological footprint of the entire company,” adds Stockfisch.

With 1,700 employees Leipa


Georg Leinfelder GmbH has sales of €565 million a year, producing 530,000t of magazine papers, 700,000t of liner, 125,000t of board, 21,000t of special papers and 400 million square metres of flexible packaging. Leipa’s most recent investment


was in the restarting of its PM5 machine in April 2018 after it was


converted to uncoated White Top Testliner. Commenting on the project, Leipa group chief executive Peter Probst said: “We look forward to growing successfully with our customers and partners. The demand for White Top Liner remains consistently high and the trend is rising. Prices are at a high level as well. These factors


result in excellent conditions for the market launch of the PM5.” Christian Schürmann,


operations chief at Georg Leinfelder GmbH added: “The entire project team has done a great job rebuilding the PM5. We will produce a state-of-the-art testliner on this machine – the world’s most powerful of its kind.”
