Customizing a Low-Pressure Pneumatic Conveying System for Chemical Powders

ZhengZhou TianQi Machinery provides customizable pneumatic conveying systems for chemical powder transfer. The system design can be evaluated according to material properties, conveying capacity, pipeline layout, and positive- or negative-pressure requirements.

Why Material Evaluation Comes First

Chemical powders can differ significantly in particle size, moisture content, temperature, flowability, and friability. These characteristics influence the required conveying pressure, air volume, pipeline arrangement, and operating conditions. A suitable low-pressure pneumatic conveying system should therefore be selected from the material and process requirements rather than from a standard configuration alone.

TianQi Machinery uses the available application information to assess the conveying route and operating mode. This approach helps align the enclosed conveying pipeline with the intended transfer process while keeping optional functions and equipment configuration relevant to the actual application.

Key Parameters for a Custom Low-Pressure System

Evaluation area	Why it matters	Possible design consideration
Particle size and material form	Affects flow behavior and the way the powder moves through the conveying line.	Selection of conveying conditions and suitable pipeline configuration.
Moisture and temperature	May influence material handling and the stability of the transfer process.	Assessment of optional heating, cooling, or drying functions.
Throughput and conveying distance	Defines the operating demand placed on the pneumatic conveying system.	Adjustment of pressure mode and conveying route.
Pipeline direction and layout	The system may need to follow horizontal, vertical, or inclined paths.	Planning of an enclosed pipeline layout for the available plant space.
Pressure and air-source requirements	Determines how the material is introduced and transported through the line.	Evaluation of positive-pressure, negative-pressure, or mixed-pressure operation.

Pressure Modes and Conveying Direction

Low, Medium, or High Pressure

TianQi Machinery can customize low-pressure, medium-pressure, or high-pressure operating modes according to the application requirements and material handling conditions.

Positive or Negative Pressure

The system can be assessed for positive-pressure, negative-pressure, or mixed-pressure conveying, depending on the process arrangement and transfer requirements.

Flexible Pipeline Routes

Horizontal, vertical, and inclined conveying paths can be considered when planning the equipment layout and connection between process points.

Enclosed Transfer for Chemical Powder Handling

The pneumatic conveying system transports powder through sealed pipelines using controlled airflow. Compared with open material transfer, an enclosed conveying design helps reduce dust release, external contamination, and material loss during normal conveying operations.

Application note: The final configuration should be determined from the chemical powder’s properties, required throughput, conveying distance, plant layout, and applicable process conditions. These details provide the basis for selecting the appropriate pressure mode and optional functions.

Optional Process Functions

In addition to conveying, the system can be evaluated for integration with process functions that support specific material-handling requirements:

Heating
Considered when controlled temperature conditions are required.
Cooling
Considered for applications where material temperature needs to be managed.
Drying
Considered when moisture-related handling requirements are part of the process.
Classification
Considered when material separation or grading is included in the process.

A Practical Customization Process

1
Define the powder and process conditions
Review particle size, moisture content, temperature, friability, throughput, and other available material information.
2
Review the conveying route
Confirm the transfer points, conveying distance, horizontal or vertical sections, inclined paths, and available installation space.
3
Select the pressure configuration
Assess low-, medium-, or high-pressure operation together with positive-pressure, negative-pressure, or mixed-pressure requirements.
4
Evaluate optional functions and support needs
Determine whether heating, cooling, drying, classification, or other customized process requirements should be included.
