GRAZ, Austria , August 3, 2022 (press release) –

International technology group ANDRITZ recently received the Final Acceptance Certificate for the upgrade of two ANDRITZ P-RC APMP (Pre-Conditioning Refiner Chemical Alkaline Peroxide Mechanical Pulp) fiberlines delivered to APP’s Guangxi Jingui Pulp and Paper, Guangxi Province, China.

The fiberlines – originally supplied by ANDRITZ in 2010 and the first mechanical pulping systems ever supplied to APP – were rebuilt to expand the aggregate capacity significantly and thus meet the considerably raised mechanical pulp demand resulting from the customer’s new board production line.

The project comprised the rebuild of the chip pre-treatment system for optimum chemical impregnation and the upgrade of the existing high-consistency (HC) refining stages with advanced feeding systems to ensure high capacity and even feeding. A new fiber-steam separation stage contributes to energy-efficiency by maximum steam recovery and low fiber losses in the steam.

The successful start-up was managed by the mill staff, supported by experienced engineers from ANDRITZ China on site as well as with the remote support from ANDRITZ experts in Europe.

Guangxi Jingui Pulp and Paper was established in 2003 and is part of Asia Pulp and Paper (APP), a leading global player in the production of a broad range of tissue, packaging, and paper products.
