Pressure Conveying in Dense Phase

Best suited for long distance conveying using high pressure compressed air.
Dustex Dense Phase Pneumatic Conveying Systems are designed for efficient, dust-free transfer of bulk materials using compressed air in pushing. Operating at low velocity and high pressure, these systems are ideal for handling fragile, abrasive, and high-density materials while minimizing product degradation and pipeline wear.
The system is suitable for long-distance conveying and ensures controlled material flow with high operational reliability.

Key Features
• Low-velocity conveying system designed for gentle material handling.
• Minimizes pipeline wear and reduces product degradation or material breakage during transfer.
• Ideal for long-distance conveying applications across industrial processing lines.
• Available with integrated pressure vessel for efficient material transfer.
• Manufactured in Carbon Steel, SS304, and SS316 construction.
• Custom-engineered solutions designed to match specific process and application needs.

Dense Phase Conveying System

Ways of Working – Dense Phase Conveying

1. Batch Conveying (Empty Pipe)

In this mode, the pipeline is emptied after every conveying cycle. Material is transferred in batches using compressed air.

Best Suitable For:
  • Short to medium conveying distances
  • Intermittent conveying applications
  • Powder and granular materials

2. Full Pipe Conveying

The pipeline remains filled during conveying, allowing material to move in dense plugs at low speed.

Advantages:
  • Ideal for long-distance conveying
  • Reduced material degradation
  • Lower pipeline abrasion
  • Energy-efficient operation

3. Full Pipe Continuous Conveying

This system uses twin pressure vessels working alternately for continuous material transfer without interruption.

Benefits:
  • Continuous conveying operation
  • Stable material flow
  • Higher productivity
  • Suitable for automated processes
