Lean Phase Pneumatic Conveying System

Advanced Lean Phase Conveying Systems Engineered for Reliable Material Handling

AERONIX Systems LLP specializes in the design, engineering, manufacturing, installation, and commissioning of Lean Phase Pneumatic Conveying Systems for handling powders, granules, pellets, flakes, and bulk solids across diverse process industries.

With over 17 years of practical experience in powder handling and bulk material conveying applications, our engineering team develops customized lean phase conveying solutions designed to maximize productivity, improve plant efficiency, reduce manual handling, and maintain product quality.

Lean phase conveying remains one of the most widely used pneumatic conveying technologies due to its simplicity, flexibility, lower capital investment, and suitability for a broad range of materials and applications.

Lean phase conveying is a pneumatic conveying method where material is transported through a pipeline while being fully suspended in a high-velocity air stream.

In a lean phase system, conveying air velocity is maintained sufficiently high to keep all particles moving continuously through the pipeline without settling.

The material-to-air ratio remains relatively low, which is why the system is referred to as “lean phase.”

This technology is widely used for conveying free-flowing powders, granules, pellets, and lightweight materials over short to long distances.

• Rotary Airlock Valve
• Screw Feeder
• Venturi Feeder
• Eductor
• Vacuum Receiver

• Roots Blower
• Positive Displacement Blower
• Vacuum Pump
• Centrifugal Blower

Material is transported through enclosed pipelines to the destination point.

• Horizontally
• Vertically
• Around obstacles
• Across multiple plant areas

At the receiving point, product separation is achieved using:

• Cyclone Separator
• Dust Collector
• Filter Receiver
• Product Hopper

Lean phase systems generally require lower capital investment compared to dense phase conveying systems.

Pipeline routing flexibility allows easy integration into existing facilities.

Suitable for handling large material transfer rates.

• Material spillage
• Dust generation
• Product contamination

Improves operator safety and workplace cleanliness.

• Weighing Systems
• Batching Systems
• Mixing Systems
• Packaging Systems
• Process Control Systems

Material is conveyed under positive pressure.

• Silo Loading
• Process Feeding
• Long Distance Transfer
• Centralized Material Distribution

Material is conveyed under negative pressure.

• Food Processing
• Pharmaceutical Production
• Chemical Manufacturing
• Packaging Operations

Used where multiple pickup and discharge points are required.
