Jun 02, 2006. /Lesprom Network/. Danish paper company Dalum Papir is to upgrade its 15-year old disperger system in its deinking plant in Naestved with a high-efficiency disperger from Voith Paper. Aim of this investment, scheduled for completion in July of this year, will be to further improve the optical quality of the deinked pulp. This is produced mainly from higher quality recovered paper grades, including office papers. This will be the second time in two years that Naestved’s stock preparation plant, originally supplied by Sulzer Escher Wyss, undergoes systematic technological modernization to suit market requirements based on customized solutions from Voith. In the first upgrade the existing MC screening was equipped with MultiFoil rotors and C-bar screen baskets and this is now followed by the installation of the new disperger. The DIP produced in Naestved is used for the production of high-grade coated and uncoated graphic papers in Dalum Papir’s mill in Odense. 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 paper technology, power transmission engineering, power generation and industrial services. Founded on January 1, 1867, it has a current workforce of approximately 30 000, sales of Euro 3.5 billion and over 200 locations worldwide, and is one of the largest family-owned enterprises in Europe.
