1. High Moisture Content in Dried Material
Causes: Excessive feed moisture, obstructed condensate drainage, insufficient material residence time, steam leakage.
Solutions: Check the extruder's dehydration effect, clean the steam trap, adjust steam pressure, and repair leaks.
2. Abnormal Equipment Operation
Abnormal Start-up: Check the power supply line, motor, and control circuit.
Excessive Noise: Tighten the fan or replace the bearings.
Improper Material Feed/Discharge: Clean any blockages at the feed inlet.
3. Temperature and Energy Consumption Issues
Poor Drying Effect: Adjust the temperature setting and check the fan airflow.
High Energy Consumption: Repair the insulation layer and replace aging parts.
4. Shaft Wear
Repair Method: Repair on-site using carbon nanotube polymer material; no disassembly required.
5. Sealing and Leakage
Steam Leakage: Replace the sealing ring or repair the valve body.
Air leakage: Check the sealing of the double piston valve and cone valve.
6. Routine maintenance recommendations
Regularly clean scale buildup in the tubing bundle, check the lubrication system, and follow standard operating procedures.
