Choosing Toughness: Material Selection for Wear Resistance in Dilute Phase Conveying


Abrasive Material Plant

Dilute phase pneumatic conveying, while offering high throughput and efficiency, presents unique challenges when handling abrasive materials. The high-velocity air stream propels material with significant force, leading to potential wear and tear on system components. Selecting the right materials is paramount to maximizing system longevity and minimizing maintenance costs. Delta Ducon prioritizes material selection to engineer dilute phase systems that withstand the rigors of abrasive material handling.


Understanding Wear Mechanisms:


To effectively combat wear, it's crucial to understand the different ways materials can degrade in a dilute phase system:


  • Abrasion: This occurs when hard particles slide or rub against a surface, gradually wearing it away.

  • Erosion: This is caused by the impact of particles on a surface, often at high velocities, leading to material removal.

  • Impact: This involves direct collisions between material particles and system components, causing deformation or damage.


Delta Ducon's Material Solutions:


Delta Ducon employs a range of advanced materials to combat these wear mechanisms in our dilute phase systems:


  • Piping:

    • Specialized Alloys: We utilize alloys with increased hardness and toughness to resist abrasion and erosion.

    • PERMA/flo: Delta Ducon PERMA/flo pipe & fittings are specifically designed to withstand the wearing action of abrasive materials when transported pneumatically.    


  • Rotary Valves:

    • Construction: Cast Iron or Stainless Steel Construction

    • Rotor Options: Closed End Rotors

    • Extreme Rotary Valves: For Severely Abrasive Applications

      • P-33 Alloy (550+ BHN) Cast Closed End Rotor & Inlet Wear Shoe    

         

  • Other Components:

    • We carefully select materials for housings, diverters, and other components based on the specific application and the abrasive nature of the material.


Conclusion:


Delta Ducon's commitment to material selection ensures that our dilute phase pneumatic conveying systems are built to last. By utilizing advanced materials we provide solutions that minimize wear, reduce maintenance, and maximize the return on your investment.
