Aquatic Feed Pellet Extruder Issues: Vibration, Noise and Jamming Solutions

 

Aquatic feed pellet making machine vibration, noise, and jamming are not separate issues-they are a linked system failure. Solving them requires a holistic approach, addressing mechanical integrity, process stability, and raw material consistency.

 

By implementing systematic diagnosis, targeted repair, and preventive maintenance, you can transform your extruder into a stable, efficient, and long-lasting production system-running smoothly, quietly, and reliably 🚀.

 

 

• nitial Stage: Slight vibration + noise, small fluctuations in current
  
• Mid Stage: Increased vibration, harsh noise, unstable output
• Late Stage: Sudden increase in current, screw jamming, equipment shutdown

 

 

• Component Wear (Screw/Bearing/Gear) → Increased Vibration → Increased Noise → Abnormal Clearance → Obstructed Material Flow → Blockage and Jamming
• Process Imbalance (Temperature/Feed/Moisture) → Abnormal Material → Sudden Load Changes → Vibration/Noise → Accelerated Component Wear → Jamming
• Material Impurities → Impact on Components → Vibration/Noise → Widened Clearance → Blockage and Jamming

 

 

1. Data Acquisition

• Record vibration values, noise levels (decibels), current, temperature, and pressure.
  
• Check raw material moisture content, impurity content, and feed rate.
• Disassemble and inspect the screw/barrel, bearings, and gearbox.

 

2. Root Cause Location

• Mechanical: Component wear, installation deviation, transmission failure
  
• Process: Temperature/ Pressure/Feed Mismatch
• Material Issues: Moisture/Impurities/Formula Abnormalities
• Operational Issues: Lack of Maintenance, Non-standard Processes

 

 

1. Mechanical System Repair

• Comprehensive overhaul of screw/barrel, repairing wear and calibrating clearances.
• Replace all damaged bearings and gears, standardize lubrication.
• Correct coaxiality, tighten foundation feet, and install shock absorbers.

 

2. Prawn Feed Pellet Making Machine Process Parameter Optimization

• Set temperature (120-180℃) and pressure according to raw material characteristics.
  
• Stable feed rate, matching screw speed.
• Precisely control moisture to ensure uniform plasticization of materials.

 

3. Material and Operation Management

• Upgrade the impurity removal system to prevent hard objects from entering.
• Standardize preheating, feeding, and shutdown procedures.
• Establish a daily inspection, weekly maintenance, and monthly overhaul system.

 

 

• Set early warning thresholds for automatic alarms in case of abnormalities.
• Regularly train operators to improve fault prediction capabilities.
• Establish equipment health records and continuously optimize maintenance strategies.
