PNEUMATIC CONVEYING SYSTEM
— Industrial pneumatic conveying systems for powders, granules, pellets, flakes and all types of bulk materials — engineered for food, chemical, plastics and battery industries.
WHY CHOOSE WIJAY SYSTEMS
——————WIJAY——————
Pneumatic conveying systems use gas to move granular, powdered, or fibrous materials through pipelines. Depending on air pressure, they operate as vacuum, positive pressure, or mixed systems, and as dense- or dilute-phase flows. They also support process controls like batching, impurity removal, metering, weighing, mixing, and recovery.
- +20% Production Efficiency: Automation boosts speed and reduces labor needs.
- –20% Labor Costs: Only 1–2 operators per line.
- Eco & Health Friendly: Dust-free, sealed, and precise material handling.
- Leak-Free & Low-Maintenance: Stable, simple, and easy to service.
- High-Precision Metering: Accuracy up to 2‰ ensures quality and fewer defects.
- User-Friendly: Highly automated for easy operation.
TYPES OF PNEUMATIC CONVEYING SYSTEMS
——————WIJAY——————
Positive Pressure Conveying System
Positive pressure pneumatic conveying systems are primarily used to transport materials from a single feeding point to multiple receiving hoppers. Compared to negative-pressure conveying systems, this system allows for a higher solid-to-gas mixing ratio and requires smaller pipe diameters and a smaller footprint.
Negative Pressure Pneumatic Conveying (Vacuum Conveying)
Vacuum conveying systems are suitable for conveying materials from multiple feeding points to a single receiving point. The conveying pressure is typically limited to approximately -0.5 bar.
Rotary Valve Pneumatic Conveying

Silo Pump Pneumatic Conveying
With high-pressure resistance and excellent sealing performance, this system is suitable for long-distance, high-capacity conveying, with a conveying pressure of up to 6 bar.
Dense Phase Conveying System
Utilizes low-velocity, high-pressure airflow to transport material in a dense plug flow or dune-like formation at high concentrations and low velocities;
The material fills most or all of the pipe cross-section. Solid loading is high, and conveying velocity is relatively low.
Dilute Phase Conveying System
Utilizes high-velocity airflow to suspend the material, enabling low-concentration, high-speed conveyance; The material is distributed almost uniformly across the pipe cross-section. Solid loading is low, and conveyance speed is relatively high.
