Pneumatic Conveying System
It is widely used in industries requiring clean, flexible, and automated material conveying, such as cement, chemical, food, fly ash, lime powder, and biomass industries.
Pneumatic conveying systems are ideal for transferring fine powders over long distances while minimizing dust pollution, material leakage, and environmental contamination. Depending on the application, the system can operate under positive pressure or vacuum conveying modes.
Positive-Pressure Dense-Phase Pneumatic Conveying System | Positive-Pressure Dilute-Phase Pneumatic Conveying System | Negative-Pressure Suction Pneumatic Conveying System |
| Main equipment of positive-pressure dense-phase pneumatic conveying includes: silo-type conveying pump, air compressor, pneumatic rotary feed valve, ceramic lined wear-resistant elbow, electrical control system, etc.These systems are used across many different bulk handling industries to convey bulk products. Higher conveying rates and longer conveying distances are often possible with dense phase conveying systems.Some of the handled bulk materials include sand, limestone, gypsum, fly ash, cement, CaCO3 and many more. | Positive-pressure dilute-phase pneumatic conveying systems are suitable for conveying pressure ≤ 100 kPa and conveying distance ≤ 200 m.Dilute phase conveying systems are the most common pneumatic conveying systems used in many bulk material handling industries to transport bulk solids.These systems are ideal for transporting non-abrasive bulk materials, products with low bulk density and bulk materials that are hard to break.Materials include sugar, flour, pellets, chemicals, polymers, calcium carbonate, cement, and coal dust. | Negative-pressure suction pneumatic conveying systems rely on airflow with pressure lower than atmospheric pressure to carry materials along enclosed pipelines for conveying. |

In Bulk Solids Handling Systems, Pneumatic Conveying Systems Are Mainly Used For:
Conveying cement, fly ash, lime powder, and mineral powder into storage silos
Transferring powders between multiple silos and processing equipment
Feeding production lines with fully enclosed material transportation
Handling materials in dust-sensitive industrial environments
Long-distance powder conveying with automated control systems
Typical Silo Matching Solution
In a fly ash storage project for a power plant, fly ash collected from dust collectors is transported through a pneumatic conveying pipeline directly into welded steel silos. The silo discharge system then feeds the material into loading or batching systems using rotary valves and screw conveyors.
