First experiences with CeraGuide B at DS Smith Aschaffenburg
Since CeraGuide B has been installed, forming fabric edge damage is now a thing of the past thanks to a unique roll end and edge radius treatment process, and wire drive stability has been excellent throughout without a single instance of slippage. The longest serving CeraGuide B cover has now been running in the machine for 5 years without interruption on the drive position of the bottom wire, where previous rolls with rubber covers had to be changed after 150 to 400 days of operation.
An additional potential for cost reduction is offered through doctoring in those roll positions. Whereas former rubber covers needed a high amount of lubrication water to avoid wear or damage from the doctor blade, CeraGuide B can be doctored without any lubrication water. For example, on PM 1, 550 l/m/min of doctor lubrication water can be saved per doctoring position. Walther Böhm, technical director at Aschaffenburg, emphasizes that in addition to the water savings, equipment costs for providing that amount of water, like pumps etc, disappear.
Against the background of a more and more critical raw material situation and the resulting sensitivity to wear in the wire section, the market request for CeraGuide B is growing constantly. This coating suits graphical as well as board and packaging applications and has proven its quality in more than 120 installations over the years. Unlike competitor products on the market, CeraGuide B is a full plasma ceramic of utmost hardness without fast wearing epoxy components. Due to its numerous benefits, CeraGuide B shows a return on investment of less than one year in most applications.
DS Smith is one of the leading manufacturers of high quality containerboard in Europe and PM 1 at Aschaffenburg produces more than 280.000 t of testliner and corrugated board annually in a basis weight range from 80-120 g/m².
