Feb 02, 2006. /Lesprom Network/. UPM reports selecting Voith Paper to optimize high density cleaning and coarse screening at its Schwedt/Germany mill. The existing single-stage high consistency cleaning will be modified to the HiPRO Protector system. The special feature of this two-stage system is its reduced sensitivity to process fluctuations. After commissioning in February this year, UPM expects to reduce heavy contaminants in the accepts and fibre losses both by 50%. To reach the project goals, which call for not just a reduction in fibre losses with a simultaneous improvement in stickies removal but also an increase in production capacity, the coarse screening will be rebuilt to the so-called combi-screening system using the existing machines. With this combined hole and IC slot screening the accepts of the second and third hole stages are subsequently screened in a two-stage slot screening system. This strategy offers cost-efficient use of the technological advantages of IC slot screening in partial flows. Major advantages of this well-proven system philosophy are a high degree of operational reliability together with maximum screening efficiency and low fibre losses. Voith will supply various screen baskets to reduce existing hole and slot width sizes, a MultiScreen pressure screen equipped with C-bar screen basket and MultiFoil rotor, as well as a Combisorter as final stage hole screen. The Combisorter is combined with a centrifugal cleaner for additional heavy contaminants removal. Two spiral feed screws provide for reject transport. The scope of supply includes erection supervision and start-up assistance as well as basic process and control engineering. The UPM Schwedt mill was founded in 1991 in Schwedt/Oder, and in 1993 a high performance Voith paper machine started up, equipped with the latest state of the art for newsprint paper production. Today, the mill belongs to the Finnish forestry and paper group UPM, with about 300 people employed at this location, and an annual production of 300 000 tonnes of high quality newsprint paper. 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.
