International technology Group ANDRITZ has received an upgrade order from Sappi North America for a high-capacity debarking line and woodyard equipment to be installed at Sappi’s Somerset Mill in Skowhegan, Maine. The new line will further reduce wood losses and enhance the mill’s reliability and performance. Commissioning of the new line, which has a design capacity of 300 t/h of hardwood chips and 270 t/h of softwood chips, is scheduled for the fourth quarter of 2017.

Over 100 HHQ-Chippers have been sold worldwide since being introduced to the market in 2001. The delivery to Sappi Somerset includes an extra-large (XXL) size chipper. This order is the second order for ANDRITZ in North-America in 2016 for a high-capacity debarking line with HHQ chipping technology.

ANDRITZ’s scope of supply includes upgrade of the log infeed, delivery of a new 38-m long debarking drum with energy-efficient steam de-icing, an extra-large (XXL) HHQ-Chipper with ANDRITZ TurnKnife and ChipperEKG condition monitoring systems, installation of a new scalping screen, and upgrade of the chip handling equipment. ANDRITZ will also deliver an advanced Automation & Industrial Internet package, including optical systems for scanning wood, chips, and bark to optimize the debarking and chip production processes, as well as data acquisition and analysis tools to improve the mill’s operational performance. 

ANDRITZ and Sappi North America have had a good business relationship for many years. Recently, ANDRITZ completed a successful project to convert the Somerset Mill’s lime kiln from oil to gas firing, which resulted in significant savings in energy costs for the mill.
