The rebuild of the packaging paper machine covered the upgrade of the press and calender sections, including extensions to the existing automation system. To improve the machine’s capacity and the surface quality of the paper, ANDRITZ relocated the existing press from the second to the third press position and installed a new PrimePress X shoe press in the second position. Due to its special shoe design, the PrimePress X enables gentle dewatering and reduced energy consumption. In the calender section, a new PrimeCal Hard hard-nip calender was installed to provide a consistent CD caliper profile, bulk control, and excellent surface finish.
The BM1 has a design speed of 800 m/min and a working width of 4.2 m. It produces White Top Liner, White Lined Chipboard, and Testliner in a range of 125–420 gsm. Start-up of the rebuilt BM1 ran smoothly according to schedule and achieved the promised guarantee values for dryness, bulk and smoothness right away. PJSC Kyiv Cardboard and Paper Mill, part of the Austrian Pulp Mill Holding, is one of the largest European cardboard and paper producers. The main raw material used for production at Obukhiv is recycled paper.
