Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Abrasive wear of chute lining
Cause: Continuous impact and sliding of bulk materials (e.g., ores, aggregates) causing gradual material loss, accelerated by high material velocity, sharp edges, or abrasive particle content.
Structural fatigue or cracking at pivot/weld points
Cause: Cyclic loading from rotational motion and material impact leading to stress concentration, exacerbated by misalignment, improper balancing, or material defects in high-stress areas.
Maintenance Indicators
  • Visible material spillage or uneven material distribution during operation, indicating lining wear or misalignment.
  • Abnormal vibrations, grinding noises, or irregular rotational motion suggesting bearing failure, structural imbalance, or obstruction.
Engineering Tips
  • Implement a routine inspection and wear monitoring program using ultrasonic thickness gauging for lining wear, and laser alignment checks for rotational components to detect issues early.
  • Apply specialized wear-resistant linings (e.g., ceramic, ultra-high molecular weight polyethylene) tailored to the material handled, and ensure proper balancing and lubrication of rotating parts to reduce dynamic stresses.
