Dense phase pneumatic conveying is a method of transporting dry, bulk materials through a pipeline using a gas, typically air, as the conveying medium. Unlike dilute phase conveying, where material is suspended in a high-velocity air stream, dense phase conveying moves material in a more concentrated manner at lower velocities.
How Dense Phase Conveying Works
In a dense phase system, a lower velocity, high-pressure gas stream is used to move material through the pipeline. The material is introduced into the pipeline in slugs or plugs, with a higher solids-to-air ratio compared to dilute phase conveying. This mode of transport minimizes the material's contact with the pipeline walls.
Key Characteristics
Low Velocity: Dense phase conveying operates at lower air velocities, reducing wear and tear on the system.
High Concentration: The material is conveyed in a high concentration, meaning the ratio of material to air is high.
Suitable for Abrasive or Fragile Materials:
Dense phase conveying is particularly well-suited for abrasive materials or fragile materials that are prone to degradation in high-velocity systems.
Applications
Dense phase conveying is used in various industries to transport materials such as:
Abrasive materials (e.g., cement, fly ash)
Fragile materials
Materials that need to be conveyed over long distances
Advantages
Reduced wear and tear on the system
Minimized material degradation
Lower energy consumption compared to dilute phase in some applications
Considerations
System complexity can be higher than dilute phase systems
May require higher initial investment
