Valmet to supply a wet end rebuild for Sappi Gratkorn Mill in Austria

Finland-headed energy and forest industry technology major Valmet Oyj has announced that it will supply a wet end rebuild with installation for Sappi Gratkorn Mill in Austria. The goal of the rebuild is to improve paper machine (PM 9) efficiency, reliability and energy efficiency. The start-up of the rebuilt machine is scheduled for 2019. Although the value of the order has not been disclosed, an order of this type is typically around EUR 10-20 million.

Headquartered in Brussels, Belgium, Sappi Europe is a leading European producer and supplier of coated fine paper, packaging and speciality papers. In Europe, the company has seven mills, 14 sales offices and 5 100 employees.

Located in in Gratkorn, Austria, the Sappi Gratkorn Mill produces 980 000 tonnes of high-quality double and triple coated papers annually which are used for premium quality publications all over the world. The mill produces 250 000 tonnes totally chlorine free (TCF) chemical pulp for own consumption and it has an annual sheet finishing capacity of 875 000 tonnes.

According to a statement, Valmet’s delivery includes a number of modifications to the paper machine wet end. The press section will be rebuilt into an OptiPress Center with modern shoe press technology and the best runnability components available in the market. OptiPress Center provides higher solids and better runnability, thus, lowers energy consumption and improves efficiency. The off-machine coater will be equipped with Valmet Water Jet Turn-up Device for fast parent roll changes. All the equipment will be delivered with the installation.

Sappi has been relying firmly on Valmet in the past years. In addition to this new rebuild for Sappi Gratkorn, six other major ongoing or already started-up projects for Sappi are Valmet-supplied, the latest ones for Sappi Lanaken (start-up in 2019), Sappi Maastricht (2018), Sappi Sommerset (USA) (2018), Sappi Kirkniemi (start-up 2017) and Sappi Gratkorn PM 11 (2014). Our good OptiPress pressing technology references combined with the outcome of higher solids and better quality were success factors in this case, too, said Riikka Antikainen, Senior Paper Technology Manager from Valmet.
