ANDRITZ to modernize DIP line at Metsä Tissue, Finland
International technology Group ANDRITZ has received an order from Metsä Tissue to modernize and upgrade the existing DIP line at the Metsä Tissue mill in Mänttä, Finland.
The new DIP line is to supply the furnish for all three tissue machines at the Mänttä mill and will process medium- to high-quality recycled paper grades to be used as raw material for production of various tissue products.
ANDRITZ will upgrade the pulping process with a new detrashing system – comprising a FibreGuard Detrasher, a FibreWash Drum, and a Detrashing Pump – to increase pulp quality through early removal of non-disintegrated reject materials.
In the three-stage coarse screening process, three new screens – type ModuScreen F and TC – with the latest slotted screen baskets and an AhlCleaner RB will be installed to ensure efficient removal of coarse contaminants at minimum fiber loss.
An ANDRITZ SpeedWasher will separate inorganic material, such as filler and coating pigments, from the fiber suspension to enable low ash content at the end of the line. An ANDRITZ Pulp Screw Press further dewaters pulp that is suitable for subsequent dispersing.
In order to meet the high quality requirements of certain tissue products, Metsä Tissue opted for installation of an ANDRITZ SelectaFlot flotation unit to improve brightness and remove ink particles at low fiber loss and energy consumption.
Basic engineering, dismantling of the existing equipment, erection, commissioning, start-up, and training will likewise be supplied by ANDRITZ to minimize the shutdown period.
Metsä Tissue is part of the Metsä Group, one of the largest forest industry groups in the world. The Mänttä mill has approximately 400 employees and produces toilet tissue, household towels, paper tissues, industrial tissue rolls, and greaseproof paper for baking and cooking. Mänttä was the first mill in Finland to use recycled fibre in tissue paper.
