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.

This case study describes three cases of bearing damage detected on the aft bearings of two refiners in a Norwegian pulp mill.

HD Technologies

Condition monitoring with High Definition (HD) technologies provides extremely long pre-warning times, thus maximizing the planning horizon for maintenance and repairs.

The Intellinova family

The Intellinova online systems combine HD measurement technologies with high-performance digital hardware to ensure the earliest possible warning of deteriorating mechanical condition.

SPM in Pulp and Paper

Condition monitoring is a cornerstone in the asset management of pulp and paper plants. Having control of the operating condition is a must to optimize plant profitability.
