In bulk material handling system design, many manufacturers face the choice between Tubular Chain Conveyors and Pneumatic Conveying Systems.
Both solutions are widely used for transporting powders and granules, but the ideal option depends on material characteristics, process requirements, and application conditions.
Tubular Chain Conveyor – Key Features
A Tubular Chain Conveyor transports materials through a fully enclosed pipeline using chains and discs to move materials steadily and gently.
Advantages
• Low-speed conveying reduces material breakage
• Fully enclosed system minimizes dust leakage
• Flexible layout: horizontal, vertical, and multi-bend routing
• Lower energy consumption
• Suitable for multiple inlets and outlets
Typical materials include:
Plastic pellets, coffee beans, animal feed, chemical powders, food ingredients, and more.
Pneumatic Conveying – Key Features
Pneumatic conveying uses air flow and pressure differences to transport materials at high speed through pipelines.
Advantages
• Suitable for long-distance conveying
• High level of automation
• Ideal for continuous high-volume transport
• Flexible pipeline configuration
System Considerations
• High conveying velocity may affect sensitive or fragile materials
• System performance varies depending on powder properties (abrasion, cohesion, moisture)
• Higher energy demand compared to mechanical conveying systems
How to Choose the Right System?
If your priorities include:
✔ Minimizing product breakage
✔ Strong dust control requirements
✔ Limited space requiring flexible routing
✔ Lower energy consumption and maintenance needs
→ A Tubular Chain Conveyor is typically the better choice.
If your requirements include:
✔ Ultra-long conveying distances
✔ High-capacity, continuous high-speed transport
✔ Existing compressed air and dust collection systems
→ Pneumatic conveying may be more suitable.
Different conveying methods directly impact production efficiency, material quality, and long-term maintenance costs.
