Dewatering equipment for TMP washing stage

Andritz has received an order from Hol­men Paper, a part of the Hol­men Group, Swe­den, to refur­bish and install dewa­ter­ing equip­ment for a new TMP (ther­mo-mechan­i­cal pulp) wash­ing stage at PM 12 in Hall­stavik. Basic engi­neer­ing, erec­tion as well as com­mis­sion­ing and start-up, which is sched­uled for the final quar­ter of 2018, are also part of the deliv­ery scope.
The com­pa­ny will refur­bish two used Andritz twin wire press­es and relo­cate an exist­ing pulp screw press. After re-instal­la­tion as the TMP wash­ing stage, the dewa­ter­ing equip­ment will improve the pulp qual­i­ty, thus ensur­ing high­er prod­uct qual­i­ty on the paper machine. PM12 man­u­fac­tures book paper and newsprint grades.
Scope of Supply

• Refur­bish­ment of two used Andritz twin wire presses.
• Relo­ca­tion and over­haul of an exist­ing pulp screw press used in the for­mer deink­ing plant at Hall­s­ta paper mill.
• Instal­la­tion of a new con­vey­or for pulp dilu­tion and shred­ding after washing.
• Rebuild and relo­ca­tion of two exist­ing screw conveyors.
