Case study: Vibration monitoring on paper machine

Swedish paper mill Stora Enso Kvarnsveden applies vibration monitoring on the PM8 super calender to optimize its operation and extend the service life of the rollers. The PM8 super calender has twelve rollers on one stack, half of which are soft (elastic) rollers that frequently become worn and corrugated and therefore need regular grinding.
