Paper Industry

Background

Paper production involves continuous processes with high-speed rotating equipment such as extraction fans, vacuum pumps, refiners, blowers, pulper motors, and conveyor systems. These machines operate in environments with high humidity, fiber dust, steam, and heavy workloads.

Frequent cleaning, water exposure, and long operating hours accelerate mechanical wear such as unbalance, misalignment, and bearing degradation.

Predictive maintenance is critical to ensure machine stability and avoid sudden failures that interrupt production lines or cause paper quality issues.

Diagnosis Process

Novaseer’s predictive maintenance system uses a standardized diagnostic workflow for all rotating equipment in paper mills:

Trend Monitoring

Abnormal vibration or temperature increases were noted during operation, often coinciding with load changes, cleaning cycles, or shifts in moisture content.

Waveform Evaluation

Time-domain waveforms showed disturbances or impact signals commonly associated with:

• Moisture-induced misalignment
• Fiber buildup on impellers or rotors
• Bearing wear from continuous operation
• Looseness caused by structural vibration

Spectrum Analysis

Frequency-domain analysis identified:

• High rotating-frequency amplitude (unbalance)
• Harmonics and sidebands (looseness/misalignment)
• Bearing characteristic frequencies (early fatigue)
• Broadband noise (water ingress or fiber buildup)

Based on combined evidence, the system issued an early warning and recommended inspection.

On-Site Inspection & Maintenance

Technicians commonly discovered:

• Pulp or fiber accumulation on blades, filters, or pump components

• Loosened bolts due to heavy vibration

early bearing wear accelerated by water or steam exposure resized

• Misalignment from moisture expansion or structural shifts

• Early bearing wear accelerated by water or steam exposure

• Rust or corrosion in humid environments

Typical corrective actions include cleaning, balancing, tightening, alignment correction, and component lubrication or replacement.

Before & After Comparison

Condition	Before Maintenance	After Maintenance
Vibration Trend	Increasing / unstable	Stable and significantly reduced
Waveform Shape	Distorted with impacts	Smooth and consistent
Spectrum	Large rotating-frequency peaks	Lower and more balanced

These improvements confirm the mechanical issue was successfully addressed.

ROI — For equipment in paper mills, Novaseer typically delivers:

• Unplanned downtime avoided: 3–8 hours

Estimated average: ~6 hours

Early detection of abnormal equipment behavior allows plants to shift corrective actions into scheduled maintenance windows, reducing costly production interruptions.

• Maintenance labor saved: 1–3 hours

Estimated average: ~2 hours

Technicians can locate failure points more quickly with system-assisted diagnostics, improving repair efficiency and reducing troubleshooting overhead.

• Secondary damage prevented: $2,000–$8,000

Estimated average: ~$5,000

Advanced warnings help avoid cascading failures—such as increased wear on drive components, overheating motors, or misalignment-related losses.

• Total estimated value: $15,000–$40,000+

Estimated average: ~$30,000

For critical assets (e.g., lehr drives, forming equipment, cold-end inspection lines), timely alerts significantly reduce the likelihood of catastrophic failures and extended downtime.

Customer Feedback

Paper mill maintenance teams report more stable machine operation, reduced vibration alarms, and fewer stoppages. Early warnings enable maintenance during scheduled downtime instead of interfering with production runs.
