How to Customize a Low-Pressure Pneumatic Conveying System for Chemical Powder Transfer

Why Consider a Low-Pressure Configuration?

Low-pressure pneumatic conveying uses controlled airflow inside enclosed pipelines to move powder or granular material. For chemical powder transfer, the system concept focuses on controlled movement, enclosed handling, and compatibility between the air source, material characteristics, and pipeline arrangement.

Key Factors for System Customization

The correct pneumatic conveying solution should be validated against the actual operating requirements rather than selected only by pressure level. TianQi Machinery can use the following factors as a basis for configuration discussions:

Selecting the Air-Source Mode

Depending on the application, the pneumatic conveying system may be configured for positive-pressure, negative-pressure, or mixed-pressure operation. Low-, medium-, and high-pressure modes are available for evaluation, while the final selection should reflect the material, route, capacity, and process requirements.

Material Protection and Maintenance Considerations

Chemical powders may have different flow, sensitivity, and wear characteristics. An enclosed system design helps support cleaner transfer and can reduce unnecessary material exposure. During solution validation, attention should also be given to wear-prone components, inspection access, cleaning requirements, and the maintenance needs of the selected configuration.

• Confirm that the conveying route is compatible with the material’s handling characteristics.
• Review bends, feeding points, discharge points, and other areas that may experience increased wear.
• Evaluate whether optional drying, cooling, heating, or classification is needed for the process.
• Define inspection and maintenance requirements before finalizing the system configuration.

A Practical Validation Path

1. Define the material: provide information about the chemical powder, its physical behavior, and material protection requirements.
2. Map the conveying route: identify the required horizontal, vertical, or inclined sections, distance, elevation, and transfer points.
3. Set operating requirements: clarify throughput, conveying frequency, pressure preference, and available plant conditions.
4. Assess process integration: determine whether heating, cooling, drying, or classification should be incorporated.
5. Review the proposed solution: confirm equipment selection, maintenance access, wear considerations, and operating logic before implementation.
