Paper Mill Equipment

Troubleshooting Tips for Paper Mill Machines

• Inconsistent Paper Quality: Check the pulp consistency and inspect forming fabrics, as uneven slurry or worn components can lead to paper defects. Adjust press and drying pressure to maintain smoothness and strength.
• Equipment Vibration or Noise: Misaligned or loose components often cause vibration and noise—check alignment, bearings, and fasteners regularly. Lubricate or replace worn parts to ensure quiet operation.
• Low Dewatering Efficiency: Inspect vacuum systems for leaks or reduced suction, and clean filters or screens that may be clogged. Monitor machine speed to optimize water removal from the pulp.
• Frequent Breaks in Paper Web: Uneven moisture or poor edge trimming can cause web breaks, so check drying levels and trimming accuracy. Maintain consistent tension throughout the production line.
• Pump or Gearbox Failure: Ensure pumps and gearboxes are properly lubricated and not overheating, as these are signs of overload or wear. Abnormal sounds often indicate potential failure and should be addressed promptly.
• Stock Preparation Issues: Look for clumping fibers or dirty screens, which affect pulp uniformity and sheet quality. Refine fibers accurately to prevent strength loss or runnability problems.
• Electrical or Control System Malfunctions: Faulty wiring, sensors, or programming settings can disrupt machine performance. Inspect and safely restart systems while following manufacturer guidelines.
