Valmet to rebuild three board machines in North America
Valmet will rebuild three North American board machines with start-ups scheduled for 2017 and 2018. The customers remain confidential. Amongst the goals of the rebuilds are increased production and the use of recycled and non-bleached fibers.
The value of the orders was not disclosed but Valmet says the combined value of these types of orders is typically €20-30 million.
“Due to (the) large installed base of paper and board machines in North America and their ageing technology, the need for machine modernizations is quite constant. (In) a number of cases, (an) important reason for the modernizations is to increase energy and resource efficiency. This is also linked to the growing trend of lightweighting in board production. Additionally our customers want to increase the use of recycled and non-bleached fibers,” said Valmet sales director Jari Siitonen.
The deliveries will include modifications to two stock prep systems and an approach flow system, a number of modifications to the wet ends of the board machines, including a new headbox, and a rebuilt forming section, a new press section, a press section rebuild and modifications to two dryer sections.
Valmet will also supply a white liquor pressure disc filter to Japan’s Mishima pulp mill in Japan. The delivery includes an OptiDisc WL filter, pumps, piping, valves, platforms, erection and start-up services. The OptiDisc WL filter is designed to produce completely clear white liquor and wash the lime mud.
