A paper machine never sleeps: rolls, dryer cans, and refiners run around the clock, and any stop in the dryer section stops production and quality with it. Continuous vibration monitoring on the machine detects roll imbalance and bearing deterioration before they print defects into the sheet. TenBN supplies the proximity systems and monitors used across press, dryer, and stock-preparation sections.
Machinery covered in this application
Typical machinery in this application:
- Press & dryer section rolls — sleeve bearings in hot, wet, vibrating frames
- Dryer cans — steam-heated, thermally loaded cylinders
- Refiners — high-energy discs whose condition drives fiber quality
- Calender rolls — precision surfaces sensitive to vibration marks
- Stock & process pumps — constant duty around the machine
What is monitored — parameters and typical faults
- Radial vibration — unbalance, misalignment, shaft rub, and journal bearing wear show up first in shaft vibration.
- Rolling-element bearing condition — spalling and raceway defects on ball and roller bearings are detected while still repairable.
- Frame & bearing-cap vibration — looseness, soft foot, and structural resonance on smaller or slower machines.
- Speed & phase reference — one keyphasor pulse per revolution anchors overspeed protection and phase analysis.
Recommended Bently Nevada building blocks
