ANDRITZ successfully starts up an innovative reject handling line at Sun Paper Savannakhet, Laos

ANDRITZ’s scope of supply includes a compete reject handling line that processes rejects from the mill’s two OCC lines and the pulp drying line on site and has a design capacity of 400 t/d.

The innovative reject line delivered and started up by ANDRITZ comprises the following key equipment:
- Reject Compactor ReCo for dewatering the light rejects from coarse and drum screening to highest dryness
- ADuro P shredder equipped with a unique knife system and a robust rotor to ensure that the material is cut to the required particle sizes in only one step
- ADuro C shredder with special coupled shafts to facilitate knife exchange during maintenance and thus reduce downtime

Ying Guangdong, Vice General Manager and Chief Engineer at the Sun Paper Group, says: “We managed a very successful start-up ahead of schedule despite the challenging impact of the pandemic. We will definitely benefit from the highly energy-efficient equipment, its long lifetime, easy maintenance and, in particular, from the powerful new reject handling system.”

In addition, ANDRITZ installed approach flow systems and broke handling as well as several stock preparation components as part of two OCC lines. The stock preparation systems feed two paper production lines that feature a maximum capacity of 1,434 t/d each and produce high-quality test liner and corrugated paper as their final product.

This successful start-up strengthens ANDRITZ’s strong position as a technology and service provider for reject handling lines in Southeast Asia. ANDRITZ has supplied three reject handling systems to Sun Paper since 2014.

Sun Paper Savannakhet was established in August 2010 as part of the Sun Paper Group, a leading player in the pulp and paper industry, and produces about 800,000 tons of packaging paper per year.
