Condition monitoring of refiner bearings

Norwegian pulp mill MMK FollaCell AS monitors critical equipment with the Intellova Compact online system. This case study describes three individual bearing damages found in two refiners.

Due to the refiner design, the conditions for measuring these bearings are not optimal, and the damage development process is often fast. Although the measured signal is dampened, it was still possible to detect these three damages in time for planned bearing changes using HD condition monitoring technology.
