Floating Aquatic Feed Pellet Machine Maintenance: Prevent Vibration, Noise and Jamming

 

Floating fish feed extruder machine maintenance isn't a chore-it's a control system. When inspection, lubrication, cleaning, calibration, and operation form a closed loop, your machine shifts from "trouble-prone" to "production powerhouse" 🚀

 

 

1. Vibration and Noise Inspection

• Observe the vibration of the pet food extruder machine and listen for abnormal noises (impact/friction/rumbling).
• Check bearing temperature (≤70℃); stop the machine immediately if abnormal.
• Record current fluctuations to assess load stability.

 

2. Transmission and Foundation Inspection

• Check anchor bolts and flange connections; tighten them promptly.
• Check belt/chain tension; adjust or replace if necessary.
• Check couplings and gearboxes to ensure they are secure. Abnormal Noise

 

3. Material and Discharge Inspection

• Monitor raw material moisture and impurities to ensure compliance.
• Observe the discharge status to determine uniformity and stability.
• Inspect the die head and clean any minor blockages.

 

 

1. Bearing Lubrication

• Spindle Bearing: Add grease weekly, replace monthly.
  
• Gearbox: Check oil level monthly, change lubricating oil quarterly.
• Ensure adequate lubrication to prevent dry running and abnormal noise.

 

2. Transmission Component Lubrication

• Chain: Apply oil weekly to prevent rust and jamming.
  
• Coupling: Check lubrication monthly to ensure good elasticity.
• Sliding Parts: Apply anti-rust oil and lubricant regularly.

 

 

1. Barrel and Screw Cleaning

• Before each shift, empty the material and clean the machine at low speed.
  
• Disassemble and inspect the barrel weekly to thoroughly remove accumulated material and charred residue.
• Never use sharp tools to scratch the inner wall of the barrel.

 

2. Die Head and Discharge System Cleaning

• Clean the die head and unclog the discharge hole each shift.
  
• Disassemble the die head weekly for deep cleaning and wear inspection.
• Ensure smooth discharge without blockages or material accumulation.

 

3. Raw Material System Cleaning

• Clean the hopper and feed inlet daily to prevent impurities from entering.
  
• Clean the magnetic separator and screen weekly to ensure effective impurity removal.
• Clean the conveying pipeline regularly to prevent material residue from clumping.

 

 

1. Installation Precision Calibration

• Monthly calibrate the equipment's levelness and foundation anchor tightness.
• Quarterly calibrate the coaxiality of the motor and main unit.
• Yearly check the foundation rigidity and reinforce as necessary.

 

2. Component Clearance Calibration

• Monthly check the clearance between the screw and barrel (0.1-0.3mm).
• Quarterly check the bearing clearance and adjust as needed.
• Replacement Ensure precise component fit to reduce vibration and wear

 

Frequency	Task
Daily	Inspection, cleaning, lubrication check
Weekly	Bearing temperature & vibration check
Monthly	Alignment calibration, system cleaning
Quarterly	Full maintenance & wear part replacement

 

 

• Before Start-up: Fully preheat; feed only when the temperature reaches the target.
• During Operation: Stable feeding; avoid sudden load changes.
• Before Shutdown: Empty material and clean at low speed.
• In case of abnormality: Stop the machine immediately; forced restart is strictly prohibited.
• Training: Operators must be certified and possess expertise in fault diagnosis and handling.
