With a belt dryer, the substrate lies on a belt running through a drying kiln. This substrate can be either flexible or non-flexible. On the belt dryer at Finipur, we can treat materials up to a width of 300 cm. For example, we have completed several projects in which we treated cardboard panels with a conductive and fire-retardant coating. Here, too, the coating is applied to the material by means of a certain technique (various possibilities), after which it passes through the drying kiln on a belt.
