In close cooperation with its customer Jiangsu Bohui Paper Industry, international technology group ANDRITZ recently achieved a milestone in high-consistency (HC) refining by processing a peak capacity of 1,300 admt/d of local hardwood chips per day and achieving sustainable production of 1,150 admt/d at the mill in Dafeng, China.
ANDRITZ supplied two separate fiberlines with capacities of 1,500 admt/d and 750 admt/d, respectively, featuring the well-proven P-RC APMP (Pre-Conditioning Refiner Chemical Alkaline Peroxide Mechanical Pulp) technology for the new chemi-thermo-mechanical pulping system. With a total capacity of 2,250 admt/d, this system is the largest worldwide.
The world record was achieved with the ANDRITZ TX68, the world’s largest HC refiner, as part of the second P-RC APMP system despite a defined single-line capacity of 750 admt/d. The TX68 refiner with an advanced feeding system is the centerpiece of the process and the latest innovation by ANDRITZ in HC refining.
Chen Bo, Pulp Production Manager at Jiangsu Bohui Paper Industry, comments: “Aiming at more flexibility for our folding boxboard production, we adapted the system in close cooperation with the ANDRITZ experts and were finally able to achieve this impressive milestone. We are especially proud that we succeeded in obtaining the necessary system configurations despite several challenges due to the Covid-19 situation. ANDRITZ China provided excellent on-site support in parallel with ANDRITZ’s key experts in Europe using remote solutions.”
