Andritz has received an order from AO Knauf Petroboard to rebuild the KM 2 board machine at its mill in Kommunar, Russia. The board machine – with a basis weight range from 100-320 g/m2, a working width of 4,260 mm, and a design speed of 700 m/min – has an annual capacity of 155,000 t/a for production of gypsum board made of 100% waste paper raw material. Start-up is scheduled for the fourth quarter of 2018.

The rebuild includes the supply of a new wire section with three PrimeForm SW Fourdrinier wires and new PrimeFlow SW headboxes, one of which contains a PrimeProfiler F consistency profiling system.

Andritz will also supply the main components in the approach flow systems for the top, filler, and back layers at KM 2. The scope of supply comprises several ModuScreen HB-E screens, which combine lowest energy requirements with minimum pulsations at lowest fiber loss. A new Andritz couch pit pulper will manage broke handling. In order to significantly improve water management of the mill, a fiber recovery system with an Andritz save-all Disc Filter will be installed.

Andritz Automation will deliver a complete new Multi Motor Drive for the entire machine as well as the electrification and automation equipment. The delivery will be handled on an EPC basis, where Andritz takes responsibility for the installation work, including piping and cabling, as well as the required supervision works related to erection, commissioning, and training.
