What is Dilute Phase Pneumatic Conveying: Delta Ducon's Solutions for Abrasive Materials

Dilute phase pneumatic conveying is a method of transporting dry, bulk materials through a pipeline using a high-velocity gas stream, typically air. In this system, material is suspended within the air stream and conveyed to its destination. While challenges exist when conveying abrasive materials, Delta Ducon has the expertise and solutions to engineer effective dilute phase systems for these demanding applications.

How Dilute Phase Conveying Works

In a dilute phase system, a blower or fan generates a high-velocity air stream. The material is introduced into this air stream through a feeding device. The air stream propels the material through the pipeline, and at the destination, a receiver or cyclone separates the material from the air for collection.

Key Characteristics

• High Velocity: Dilute phase conveying relies on high air velocities to maintain material suspension within the pipeline.

• Low Concentration: The material is conveyed in a relatively low concentration, resulting in a high ratio of air to material.

• Delta Ducon's Focus on Abrasive Materials: While high velocities can pose challenges with abrasive materials, Delta Ducon specializes in designing dilute phase systems that can effectively handle these applications.

  
  

Delta Ducon's Solutions for Abrasive Materials in Dilute Phase Systems

Delta Ducon recognizes the potential challenges of abrasive wear and material degradation in dilute phase conveying. That's why we offer specialized solutions to mitigate these issues and ensure efficient and reliable operation:

• Specialized Component Engineering: Delta Ducon provides and manufactures a complete line of rotary valves (airlocks), abrasion-resistant pipes and fittings (elbows) called PERMA/flo, and more designed to withstand the harsh conditions created by abrasive materials.   

• PERMA/flo Solutions: Delta Ducon PERMA/flo pipe and fittings are specifically designed to resist the wearing action of abrasive materials transported pneumatically.  This significantly extends the life of the system and reduces maintenance.   

• Extreme Rotary Valves: Delta Ducon's line of rotary valves includes Extreme Duty options featuring P-33 Alloy (550+ BHN) Cast Closed End Rotor & Inlet Wear Shoe, field adjustability, and replaceable components for severely abrasive applications.    

• System Optimization: Delta Ducon's experienced engineers carefully design dilute phase systems to minimize wear points and optimize airflow, ensuring efficient material transport while reducing component stress.
