The Archangelsk Pulp & Paper Mill (APPM), the largest producer of packaging papers in Russia, recently put its BM 1 board machine in Archangelsk back into service following an extensive rebuild by Voith.
Voith‘s scope of supply included the approach flow system, the headbox and a new top wire. The bottom wire was rebuilt by Voith to meet the new requirements.
The new approach flow system for the top wire consists of IntegraGuard and MultiScreen screens and the associated pumps. The headbox is a MasterJet Pro. The former section was extensively modernized and a new TopFormer F installed to further improve dewatering and quality.
In addition to the machine rebuild, Voith also undertook the basic engineering and supervised commissioning. The rebuild and assembly took just ten weeks and the warranted parameters for the machine were successfully achieved within three months after startup.
Not only did the rebuild of the wet section of the BM 1 improve board quality — following startup of the new semi-chemical pulp mill and depending on a few other technical measures — the production capacity of the BM 1 will also be increased in the future.
APPM is owned by Pulp Mill Holding GmbH, an Austrian-German group headquartered in Vienna, Austria. The company produces paper, board and corrugated grades in Russia and Ukraine.
