Wet Grinding Mill Maintenance Guide
Daily Maintenance
Lubrication Management
Inspect bearings, gearboxes, and gears daily for proper lubrication. Ensure oil levels are adequate and clean.
Replace lubricating oil every 1 month after initial operation, then every 6 months or as per intermediate maintenance schedules. Use high-temperature anti-wear grease to prevent failure due to excessive bearing temperatures (≤80°C) .
Cleaning and Inspection
Remove residual materials from the grinding basin daily to prevent damage from hard debris (e.g., metal fragments).
Check belt tension, bolt tightness, and abnormal vibrations/noises in components.
Periodic Maintenance
Routine Servicing
Weekly: Inspect wear-prone parts (e.g., liners, gears) and replace damaged components.
Monthly: Thoroughly clean internal components, check gearbox wear, main bearing clearance, and adjust grinding roller-to-basin gaps .
Critical Component Maintenance
Bearings: Monitor temperature (max 55°C temperature rise) and noise weekly. Replace if abnormal.
Rollers/Basins: For split-type rollers, replace only worn rings. Basin replacement requires realigning the buffer sand layer and securing the new basin .
Operational Protocols
Pre-Startup: Allow 3–5 minutes of no-load rotation to confirm normal operation. Avoid overloading.
During Operation: Continuous monitoring is mandatory. Halt immediately if vibrations, motor overheating, or abnormal noises occur.
Post-Shutdown: Clear residual materials and conduct post-operation inspections.
Safety Precautions
Assign a dedicated supervisor when inspecting the grinding basin interior.
Avoid bolting the frame to the foundation; use shock-absorbing pads to minimize vibrations .
By adhering to these protocols, equipment reliability and service life can be significantly enhanced. Maintenance intervals may vary based on mill type (e.g., 1600/1200 models) and operational intensity.
