The core equipment supplied by Andritz originates mainly from Finland, with a significant part being fabricated at the Andritz workshop in Savonlinna.

Andritz supplied the following equipment to Metsä Group’s bioproduct pulp mill:

• a wood processing plant, including three debarking and chipping lines, boasting the highest capacity in the world (pine/spruce/birch: 470/350/270 m3 solid-over-bark per hour);
• a flexible softwood/hardwood fiberline, promising the highest softwood capacity in the world (3,900 tonnes per day);
• what it says is the world’s most energy-efficient black liquor evaporation with the highest capacity in Europe (1,650 tonnes/hour); and
• what it describes as the largest recausticizing plant in Europe (white liquor production of 16,000 m3/day).

“Andritz is our long-term co-operation partner with whom we have developed our mills consistently. In the bioproduct mill project we have used an open-book project model, which has created good prerequisites for co-operation useful to both partners. The result is a world-class mill, which was built on time and on budget,” noted Timo Merikallio, project director from Metsä Group.
