Dilute Phase Pneumatic Conveying
High velocity, low pressure and low solids loading – simple and economical.
Overview
- Conveying mode
- Positive-pressure dilute phase
- Characteristics
- High velocity, low pressure, low solids loading
- Suitable materials
- Materials that tolerate attrition
- Air control
- ACU air control unit
- Scope
- Design, supply, installation and commissioning
Dilute phase conveying moves material at high velocity, low pressure and low solids loading. The system is simple and economical, suited to materials that tolerate attrition. We define the solution from your material properties, conveying distance and capacity, and provide design, supply, installation and commissioning.
Dilute or dense phase?
If the material tolerates attrition and a simple, economical system matters most, start with dilute phase. If the material is fragile or high-value, or dust and streamers must be minimized, consider dense phase pneumatic conveying.
System components
Feeding in
Big-bag stations, sack tip stations, container discharge units
Metering
Rotary valves for pellets or powders
Piping & diverting
Conveying pipes, diverter valves, knife gate valves
Air control
Air control unit (ACU) adjusts valve opening and air flow from pipeline pressure
Storage
Storage silos, blending silos and other process silos
Dust collection
Silo-top filters and bag filters
Industries
Plastics production and compounding projects can use dilute or dense phase as required. For food, pharmaceutical and battery materials with cleanliness or metal-contamination requirements, the conveying mode is confirmed for each application.
Reference applications of the same equipment series
| Material | Capacity | Conveying distance |
|---|---|---|
| PMMA | 12 t/h | Up to 93 m |
| PMMA | 8 t/h | Up to 75 m |
| ABS | 10 t/h | Horizontal 190 m, vertical 40 m |
Reference applications of the same equipment series. Distance is the longest run, or the horizontal and vertical distance. Each solution is confirmed by material testing, conveying distance and capacity.
FAQ
What is dilute phase pneumatic conveying?
It is a way of conveying powders and pellets with gas through a closed pipeline, characterized by high velocity, low pressure and low solids loading.
