International technology Group ANDRITZ has received an order from Metsä Board, Finland, to upgrade two ANDRITZ screw presses at its Kaskinen mill in Finland.

Start-up is scheduled for the first quarter of 2019.

ANDRITZ will upgrade two pulp screw presses so that they can be utilized as bleach presses in parallel with two existing ANDRITZ twin wire presses. The upgraded screw presses will ensure the availability of the BCTMP (bleached chemi-thermomechanical pulp) line even during maintenance work.

The scope of supply includes:

  • New screw shafts equipped with modern wear protection (wear shoes and body plates)
  • New low-pressure and medium-pressure screen baskets in split design; with exchangeable, grooved screen plates
  • New headboxes
  • Relocation of the screw presses, including erection work and assembly with new components
  • Start-up support

Metsä Board decided to place this upgrade order with ANDRITZ based on their very good experience with joint screw press projects in the past at Metsä Board's Joutseno mill in Finland.
