How can I determine the right pneumatic conveying system for my needs?

How can I determine the right pneumatic conveying system for my needs? – Choosing the right pneumatic conveying system depends on multiple factors related to the material being conveyed, the process requirements, and installation constraints. Here’s a step-by-step guide to help you determine the right system:


✅ 1. Understand Your Material Properties

Key characteristics of the material will directly influence the design:

  • Bulk density (kg/m³)

  • Particle size and shape

  • Moisture content

  • Flowability

  • Abrasiveness

  • Fragility

  • Hygroscopicity

  • Explosiveness (ATEX zone?)

📌 Example: Fine, hygroscopic powders like lactose or starch may require dense phase vacuum transfer to prevent clogging and moisture absorption.


✅ 2. Determine Required Conveying Rate

  • Throughput rate (kg/hr or tons/hr)

  • Distance (horizontal + vertical)

  • Number of transfer points

  • Batch or continuous conveying

📌 Longer distances and higher flow rates often favor pressure systems.


✅ 3. Select Between Lean Phase and Dense Phase

Lean Phase (Dilute) Dense Phase
High air velocity (15–30 m/s) Low air velocity (2–8 m/s)
Lower material-to-air ratio High material-to-air ratio
Suitable for non-fragile, free-flowing materials Best for fragile, abrasive, or cohesive powders
Faster, more common Gentler, energy-efficient

✅ 4. Choose Pressure vs. Vacuum System

Pressure System Vacuum System
Best for long distances, multiple discharge points Ideal for short distances, multiple pickup points
Higher throughput Cleaner (no leakage)
Used in dense and lean phase Often used for fragile or dusty powders

✅ 5. Consider Layout & Plant Conditions

  • Space availability

  • Access to utilities (air compressor, blower, vacuum pump)

  • Explosion protection (ATEX)

  • Cleanability (CIP/SIP)

  • Product changeover frequency


✅ 6. Automation & Integration

  • Do you need PLC-based automation?

  • Should it integrate with your existing SCADA or MES systems?

  • Level sensors, diverter valves, rotary airlocks, etc.


✅ 7. Consult with a Specialist

Given the complexity and importance of proper design, always consult with a pneumatic conveying system supplier like Pneuconveyor System & Engineers. They can:

  • Analyze your material (lab testing)

  • Propose suitable conveying technologies

  • Provide custom engineered solutions


🔧 Example Scenarios

  1. Transferring milk powder to a packaging lineVacuum dense phase system for hygiene and gentle handling.

  2. Moving cement from silo to hopperLean phase pressure system for high capacity over long distance.
