1. Pre-Start Inspection
Check rollers, bearing housings, and drive belts for proper tension; ensure no looseness, cracks, or abnormal noise
Confirm the cooling water system is unobstructed, with normal pressure and temperature, and no leakage or blockage
Inspect the binder spray system and atomizing air lines; ensure no nozzle blockage or adhesive leakage
Clean residual fibers from the feed inlet and fiberizing chamber to prevent blockage and uneven loading
Lubricate all designated points with high-temperature grease; verify oil level and quality meet specifications
2. Monitoring During Operation
Continuously monitor temperatures of the main shaft and roller bearings; stop immediately if overheating occurs
Ensure motor current and rotational speed remain stable, with no significant fluctuations or abnormal vibration
Check cooling water flow and temperature to ensure effective cooling in high-temperature zones
Listen for abnormal sounds such as friction, impact, or high-pitched noise
Ensure binder spraying is uniform and stable, with no interruption, dripping, or uneven distribution

3. Post-Shutdown Maintenance
Thoroughly clean rock wool fibers and buildup from rollers and the chamber
Shut off water, air, and adhesive systems; drain residual media to prevent freezing, blockage, or curing
Clean the machine exterior and inspect fasteners, guards, and seals
Record operating data and any abnormalities for maintenance tracking
For long-term shutdown, periodically rotate the shaft and apply anti-corrosion and dust protection
4. Maintenance of Wear Parts
Rollers / Sleeves: Inspect for wear, deformation, and cracks; replace if out of tolerance
Bearings: Re-grease regularly; monitor vibration and temperature to prevent failure
Belts / Couplings: Check for wear, slippage, or misalignment; adjust or replace as needed
Nozzles & Glue Valves: Clean and unclog regularly to maintain proper atomization
Seals: Ensure resistance to high temperature and fiber abrasion; replace if aged or damaged

5. Key Practices to Extend Service Life
Do not operate under overload, overspeed, or over-temperature conditions
Maintain a stable and reliable cooling system-it is critical to equipment performance
Prevent foreign objects from entering the fiberizing chamber to avoid roller damage
Follow proper lubrication practices (correct type, quantity, and intervals); do not mix lubricants
Address minor issues promptly to prevent major failures
