Valmet Coater Roll Cover CC provides four times longer operating cycles at Metsä Board Husum mill
Aug 25, 2015
The Metsä Board Husum mill had problems with wear at backing roll due to the hard-coated blades wearing the rubber cover edge.
Since Valmet Coater Roll Cover CC was taken into use, we haven’t had to worry about how long the rolls will last. This has made it much easier to plan roll changes in a controlled manner.”
