Why Do Some PP Manure Belts Fail Early? 4 Common Issues

① Low-Quality Material (High Recycled Content)

• Symptoms: Brittleness, rough texture, cracks within 3-6 months.
• Solution: Choose virgin PP material and request material test reports.

② Insufficient or Uneven Thickness

• Symptoms: Thin belts (<1.5mm) puncture easily, especially in cattle/hog farms.
• Solution:
  • Poultry: ≥1.5mm
  • Swine: ≥2.0mm
  • Cattle: ≥2.5mm (reinforced belts recommended).

③ Poor UV Resistance (Outdoor Degradation)

• Symptoms: Hardening, fading after 3 months of sun exposure.
• Solution: Opt for UV-stabilized modified PP or install shade structures.

④ Improper Installation (Misalignment Causes Edge Wear)

• Symptoms: Rapid edge wear, reducing lifespan by 30%+.
• Solution:
  • Adjust tension properly (should depress ~1cm when pressed).
  • Regularly check tracking systems.
