Andritz upgraded screw presses for Metsä Board

Graz, Austria-based Andritz will upgrade two of its screw presses at Metsä Board’s Kaskinen mill in Finland. Start- up is scheduled for 1Q19.

With the upgrade, the presses can be used as bleach presses in parallel with two existing Andritz twin-wire presses. The upgraded screw presses will ensure the availability of the BCTMP line even during maintenance work.

The scope of supply includes: New screw shafts equipped with modern wear protection (wear shoes and body plates); new lowand medium-pressure screen baskets in a split design with exchangeable, grooved screen plates; new headboxes. Relocation of the presses, erection work and assembly with new components, and start-up support are part of the order.

Metsä Board produces premium fresh fiber paperboard including folding boxboard, food service board and white kraftliner. The Kaskinen mill produces market BCTMP as well as pulp for Metsä Board’s own board mills.
