Low Velocity Pneumatic Conveyor Solution for Fragile Materials

Product introduction for Low Velocity Pneumatic Conveyor

The low velocity pneumatic conveying system is an advanced bulk material transport solution that uses compressed air to transfer materials through enclosed pipelines. Unlike high-speed dilute phase systems, it operates at low air velocity, ensuring gentle handling of fragile materials.

It is widely used for transporting powders, grains, cement, fly ash, sugar, salt, plastic pellets, starch, and chemical materials. The system can operate under positive pressure or vacuum (negative pressure) conditions, depending on process requirements.

Made of stainless steel 304 or SS316, it is suitable for hygienic, corrosive, and industrial environments requiring reliable and continuous conveying performance.

Working principle

Step 1: Air Compression
Compressed air is generated by a blower or air compressor system.

Step 2: Material Feeding
Bulk materials are introduced into the conveying pipeline from storage silos or feeding hoppers.

Step 3: Low Velocity Flow Creation
Controlled airflow creates low-speed dense phase movement inside the pipeline.

Step 4: Pipeline Transport
Materials are pushed or pulled through enclosed stainless steel pipelines with minimal damage.

Step 5: Separation Process
At the discharge point, air and material are separated using cyclone or filter systems.

Step 6: Material Discharge
Final materials are discharged into silos, reactors, or packaging systems.
