The average service life of the core components of the Darin® fish feed machine depends on usage intensity, raw material type, maintenance frequency, and operational settings. That said, our machines are built with durable industrial-grade components and designed for long-term operation.
| Component | Estimated Service Life | Remarks |
|---|---|---|
| Main motor | 8–10 years (or more) | From top brands like Siemens or equivalent; life extended with proper voltage and load |
| Gearbox / Reducer | 6–10 years | Heavy-duty build; periodic lubrication required |
| Screw elements | 1,500–3,000 operating hours (normal wear) | Depends on formulation abrasiveness and cleaning frequency |
| Barrel segments | 3–5 years | Wear-resistant alloy lining; longer life with high-quality materials |
| Cutting blades | 300–800 hours (replaceable) | Sharpening or replacement required depending on feed hardness |
| Bearings & seals | 1–3 years | Regularly greased and replaced as part of preventive maintenance |
| Heating elements | 2–4 years | Depends on stability of power supply and operating temperature |
| PLC & electrical parts | 5–10 years | Industrial-grade, typically maintenance-free under proper conditions |
Use properly pre-ground and mixed feedstock
Regular cleaning and lubrication (follow our O&M manual)
Avoid running machine under overload or voltage fluctuations
Install inline magnetic separators to reduce metal wear
Keep extruder within designed moisture and fat input ranges
For normal commercial use (8–10 hours/day), we recommend stocking:
Screw elements: 1 full set every 12–18 months
Cutting knives and bushings: Monthly or quarterly
Bearings/seals: 1–2 sets per year

Great question. Below is a structured summary of the most common failures that may occur with a fish feed machine (extruder-based), along with causes and practical solutions, based on Darin®’s experience with global installations:
| Issue | Possible Cause | Solution |
|---|---|---|
| 1. No material discharge / blocked extrusion | - Screw jamming |
Raw material moisture too low
Foreign object inside barrel | - Check and clean screw/barrel
Adjust feed moisture (12–15%)
Inspect and remove any blockage |
| 2. Unstable pellet shape or size | - Worn or misaligned die
Inconsistent raw material mixing
Cutter speed mismatch | - Replace or clean die
Ensure consistent mixing in pre-processing
Adjust cutter motor speed |
| 3. Pellet not floating / too dense | - Low starch content
Insufficient barrel temperature
Incorrect screw configuration | - Add more starch (10–15%)
Increase preconditioning or barrel temp
Optimize screw layout |
| 4. Pellet breakage / powdering | - Overdrying
Die too small or worn
Low binder or fat in formula | - Reduce dryer temperature or time
Replace die
Adjust formulation (add binder/fat) |
| 5. Motor overload or sudden stop | - Material buildup or blockage
Overfeeding
Bearing or gearbox issues | - Stop machine and clean barrel
Adjust feed rate
Inspect motor/bearing temperature and lubricate |
| 6. Abnormal noise / vibration | - Loose bolts or couplings
Worn bearings or misaligned shafts
Screw damage | - Tighten mechanical parts
Replace bearings
Inspect and replace screw if needed |
| 7. Control panel (HMI/PLC) not responding | - Power fluctuation
Faulty wiring or screen
Software crash | - Check power supply and wiring
Reboot system
Contact Darin for firmware reload |
| 8. Oil coating not uniform | - Clogged nozzles
Low oil temperature or poor atomization
Uneven feed flow | - Clean sprayer
Warm oil to improve flow
Adjust flow rate or use vacuum coater |
| 9. Dryer not working properly | - Fan motor failure
Belt misalignment
Temperature sensor fault | - Inspect fan and motor
Adjust belt tension
Calibrate or replace temperature sensor |
| 10. Output below rated capacity | - Screw wear
Raw material variation
Moisture or feed rate too low | - Replace worn screw elements
Adjust formulation
Recalculate feed input rate |
Conduct daily cleaning of screws and feeding zones
Follow the lubrication schedule for motors and bearings
Keep a spare parts stock of high-wear items (cutters, seals, heating elements)
Regularly calibrate sensors and check HMI logs
Maintain proper voltage and grounding to protect the control system
