Rotary dryers are widely used in chemical, pharmaceutical, food and other industries. Long-term operation can lead to problems such as component wear, lubrication failure, and seal aging. Regular maintenance can effectively:
✔ Reduce unexpected downtime
✔ Extend equipment life
✔ Improve drying efficiency
✔ Reduce maintenance costs
Daily maintenance steps for rotary dryers
1. Daily inspection
• Check the operating status: Observe whether the motor and transmission system have abnormal vibration or noise.
• Monitor temperature: Ensure that the heating system is stable to avoid overheating damage.
• Clean the inlet/outlet: Prevent material accumulation from affecting the drying effect.
2. Weekly lubrication and maintenance
• Bearing lubrication: Use high-temperature grease (such as lithium-based grease) and replenish it every 100 hours of operation.
• Chain/gear inspection: Remove old grease and reapply to avoid dry friction.
• Motor heat dissipation: Clean the dust on the fan and heat sink to ensure good heat dissipation.
3. Monthly in-depth maintenance
• Seal ring inspection: If aging or damage is found, replace it in time (high-temperature resistant silicone seal ring is recommended).
• Belt tightness adjustment: Too loose will cause slipping, too tight will increase the bearing load.
• Electrical system detection: Check whether the terminal is loose to avoid short circuit risk.
Common troubleshooting and solutions
Failure phenomenon
Possible cause
Solutions
Dryer failed to start
Power failure, motor damage
Check circuit, test motor resistance
Large running noise
Bearing lack of oil, loose parts
Add grease, tighten bolts
Unstable temperature
Heating tube damage, thermostat failure
Replace heating element, calibrate thermostat
Too much material residue
Too low speed, insufficient air volume
Adjust speed, clean filter
Annual maintenance recommendations
Comprehensive disassembly and inspection: Clean the inner cylinder and check the wear.
Replace wearing parts: Including seals, belts, bearings, etc.
System calibration: Recalibrate the temperature control and speed meters.
Safety test: Ground detection, overload protection function verification.
Precautions for safe operation
⚠️ Be sure to cut off the power supply and release the pressure before maintenance!
⚠️ Do not rinse the motor or control panel directly with water.
⚠️ Use original accessories to avoid compatibility issues.
Following the maintenance process in this guide can greatly reduce the failure rate of the rotary dryer. If you need technical support, it is recommended to contact the equipment manufacturer or the professional maintenance team.
