UPM's Chapelle Darblay mill in Grand Couronne, France, has recently successfully retrofitted and started-up a Voith Paper C-bar C screen basket in an existing Kadant-Lamort SPN 15 screening machine.The extra screening capacity allowed the permanent shutdown of one of the two parallel SPN 15 screens, which is equivalent to a saving of approximately 560 MWh per year or more than 30,000 Euros per year. The unique manufacturing concept with more open area and an optimum profile performance resulted in a higher screening capacity. Therefore, the installation of the C-bar C led to an improved sticky removal efficiency by eleven percent (85 percent instead of 74 percent).
