Nov 14, 2005. /Lesprom Network/. By modifying two older type Finckh screens from centripetal to centrifugal operation at Metsä Tissue Raubach, Germany, the mill has achieved an increase in production while improving screening efficiency and reducing specific energy. Both screens operate in parallel as first stage screening in the approach flow system ahead of PM 3 headbox. A new, second screening stage ensures continuous, economic reject discharge with minimum fiber losses. Rebuilding the Finckh screens required no foundation work but just the exchange of the rotors and screen baskets as well as some piping adaptation work. This meant the mill could carry out the rebuild during a minor shutdown in summer this year. Shortly after start-up PM 3 was running smoothly and with excellent screening results. Voith screens operate with both hole and C-bar wedge wire screen baskets. Metsä Tissue's combination of the Voith Contour small hole screen basket with the MultiFoil rotor has proven most successful. Following the rebuild, production on PM 3 has increased by 20% to approximately 85 t/24 h (air dry) over a basis weight range of 15.2 to 17.1 g/m2. The Raubach mill produces hygiene papers and paper towels on two paper machines using recovered paper and chemical pulp. Several converting lines at the same site process the products ready for sale. Voith Paper is a division of the Voith Group and one of the leading partners to the paper industry. More than one third of the world's paper production is produced on Voith Paper machines. Voith sets standards in the paper, energy, mobility and service markets. Founded on January 1, 1867, it has a current workforce of 30 000, sales of Euro 3.5 billion and over 200 locations worldwide, and is one of the largest family-owned enterprises in Europe.
