Multifunctional and very flexible, the stock preparation is equipped with the Voith LowEnergyFlotation (LEF), the latest generation of deinking flotation for removing ink and hydrophobic contaminants from recovered paper. The LEF is easy to operate, low-maintenance and self-cleaning. The energy requirement is low at 10 to 15 kWh/day. The LEF thus promises high energy savings of up to 50% compared with the model previously installed.
Schönfelder Papierfabrik decided in favor of the new InfiltraDiscfilter in the BlueLine product line, along with other products. It guarantees that the pulp suspension is dewatered reliably and in an almost maintenance-free way. The core of the InfiltraDiscfilter is its bag-free BaglessPlus disc. This disc filter has an especially high capacity, since the filter surface is increased due to the corrugated surface. In addition, Schönfelder Papierfabrik chose a new dispersion system from Voith.
Holger Hampel, Manager of Schönfelder Papierfabrik, emphasizes the success of this project: “You can rely on Voith’s quality. On the basis of the very good quality and performance data achieved from the very beginning, we were able to approve the system without warranty runs. The result simply convinced us.”
Schönfelder Papierfabrik in Annaberg-Buchholz, Germany, produces more than 50,000 metric tons of graphic paper and specialty paper annually on a working width of 3,300 mm in a basis weight range of 45 to 120 g/m². The product line includes various paper grades such as offset, office, volume, envelope and improved newsprint as well as wallpaper base and liner paper.
