Erosion-Corrosion Wear in Paddle Dryers

Erosion-Corrosion in Paddle Dryers: Challenges and Solutions

Paddle dryers are workhorses in industries like sewage sludge, chemical processing, pharmaceuticals, and food production. Their rotating paddle shafts agitate and dry materials, but over time, they’re vulnerable to erosion-corrosion wear. This phenomenon can lead to costly repairs, downtime, and compromised product quality.

Understanding Erosion-Corrosion Wear

Erosion-corrosion occurs when the abrasive action of solid particles (erosion) combines with the corrosive effects of chemicals or moisture (corrosion). In paddle dryers, this wear typically affects the leading edges of the paddles, where contact with material is most intense.

Key Factors Influencing Erosion-Corrosion in Paddle Dryers:

  • Base Material Type: Low-alloyed steel wears faster than higher alloys.
  • Particle Size and Hardness: Larger, harder particles accelerate erosion.
  • Chemical Composition: Corrosive substances worsen wear rates.
  • Temperature and Moisture: High temperatures and moisture can exacerbate erosion and corrosion.

Thermal Spray Cladding: A Powerful Solution for Agitators’ Life

Thermal spray cladding is a proven method to protect paddle dryer components from erosion and corrosion. This process involves applying a thin cladding of wear-resistant material to the paddle shaft surfaces. The result? A barrier that drastically extends the equipment’s lifespan.

Key Advantages of Thermal Spray Cladding for Paddle Shafts:

  • Improved Wear Resistance: Cladding materials for Agitators are selected for their exceptional resistance to abrasion and corrosion.
  • Extended Equipment Life: Protected paddle shafts last significantly longer, reducing the frequency of replacements.
  • Enhanced Efficiency: Smoother, coated surfaces can improve heat transfer and mixing efficiency within the dryer.
  • Reduced Maintenance: Fewer repairs and replacements mean lower overall maintenance costs.
