The 24 ft MG steel
Yankee is the largest of its kind worldwide
company in its aims. Says Andreas Rauscher, chief executive of Zellstoff Pöls AG: “We have a strong intention to achieve together something extraordinary at all levels of cooperation, whether in management or in technology. “Andritz does not simply supply machines, but also supports us in the role of consultant and system supplier from the first to the last moments of a project. The formula ‘one plus one is more
than two’ really does apply to the relationship between our two companies.”
A special machine concept The PM3 project launched in August 2017 bears witness to this. As with PM2, Andritz developed and supplied the new production line, including stock preparation and approach flow system, automation technology, process pumps and, of course, the paper machine itself.
PM3 went into operation at the end of May 2019, two weeks in advance of the scheduled project date, and has since been producing kraft paper for a wide range of packaging applications as well as release papers. With an annual capacity of 100,000 tonnes, a design speed of 1,400 metres per minute, and a working width of 5.4 metres, it is the largest machine of its kind in Europe. The customised concept, which is characterised by efficient refining, a specially-designed wire section, and a closed draw press, among other elements, is said to be unique. The configuration allows flexible production of paper qualities with maximum strength, high printability, and low basis weight.
“PM3 specialises in high-quality papers with basis weights of less
than 28 g/sqm, thus perfectly complementing PM2,” says Werner Hartmann, managing director of the Starkraft business unit of Zellstoff Pöls AG. “Due to their low basis weight, these paper grades are environmentally friendly and have a very good price-performance ratio. This is precisely why our customers in growth markets are increasingly asking for these grades.” Some special machine
components are required to produce MG paper. An impressive component is the high-precision steel Yankee, where the paper is dried and the required surface property of the paper is created. The PrimeDry MG Steel Yankee from Andritz, with a diameter of 7,315mm (24ft) and a weight of 200 tonnes, is the largest of its kind worldwide. “Logistics was one of the most
exciting phases of the project,” recalls Siegfried Gruber, head of project engineering at Zellstoff Pöls AG. “On 4 August 2018, the individual parts were brought to the site on trucks on the interstate freeway as scheduled before being welded together by Andritz experts on site in the weeks that followed. In November, a huge, special crane lifted the Yankee into the machine hall.” MG cylinders (Yankees) made of 4
