Pneumatic Conveying System FAQs

A pneumatic conveying system transports powders, granules, pellets, and bulk solids through pipelines using air or gas as the conveying medium.

The main types are Lean Phase Conveying, Dense Phase Conveying, Vacuum Conveying, Pressure Conveying, and Closed Loop Conveying Systems.

3. What is the difference between lean phase and dense phase conveying?

Lean phase uses higher air velocities while dense phase uses lower velocities and higher pressure for gentler material handling.

Flour, starch, sugar, milk powder, PVC resin, carbon black, calcium carbonate, talc, pigments, fly ash, and many other powders and granules.

Dust-free transfer, flexible routing, reduced contamination, lower manual handling, and improved automation.

6. How far can a pneumatic conveying system transport material?

Distances vary from a few meters to several hundred meters depending on material characteristics and system design.

It is the speed of air inside the conveying pipeline required to transport material.

Low air velocity, poor system design, material build-up, excessive moisture, or incorrect feeding.

Yes. Dense phase conveying is often preferred for abrasive materials.

Yes. Hygienic food-grade designs are widely used in food processing industries.

A vacuum conveying system transports material using negative pressure.

Engineered for Reliability

A pressure conveying system uses positive air pressure to move material through pipelines.

A system that uses inert gas instead of air for oxygen-sensitive or hazardous materials.

Food, dairy, pharmaceutical, chemical, plastic, mineral, pigment, recycling, and battery material industries.

Bulk density, particle size, moisture content, conveying distance, capacity, and material characteristics.

The minimum air velocity required to keep material moving without settling.

Yes. Diverter valves and automation can direct material to multiple locations.

Using cyclones, filters, receivers, or dust collection systems.

Yes. Existing conveying systems can often be modified for improved performance.

Selection depends on material properties, distance, capacity, product sensitivity, and budget.
