In the world of material handling and processing industries, ensuring precise control over the flow of materials is paramount. Air slide fabric, a specialized conveyor technology, plays a pivotal role in achieving this control.

Air slide fabric, also known as aeration fabric, operates on a fascinating principle of fluidization. It consists of a permeable fabric material, typically woven polyester or nylon, which allows air to pass through it while retaining solid particles on its surface.

Top 4 key components of an air slide system

  1. Permeable Fabric: The fabric forms the conveying surface where material is transported. Its permeability allows air to pass through, creating a fluidized bed of material.
  2. Air Supply: A blower or air compressor supplies pressurized air to the underside of the fabric, creating a cushion of air between the fabric and the material.
  3. Material Inlet: Material is introduced onto the fabric through a feed point, typically at the upper end of the conveyor.
  4. Material Outlet: At the other end of the conveyor, the material flows out, either by gravity or mechanical means, into the desired processing or storage location.

Top 5 Advantages of Air Slide Fabric in Material Flow Control

Air slide fabric offers several distinct advantages when it comes to material flow control:

  1. Uniform Material Flow: The fluidized bed of material created by air slide fabric ensures a consistent and uniform flow, minimizing issues such as material segregation and rat-holing.
  2. Gentle Handling: Air slide fabric provides gentle handling of materials, making it suitable for delicate or friable substances that could be damaged by more aggressive conveying methods.
  3. Precise Control: Operators can precisely control the airflow and, consequently, the material flow rate, allowing for fine-tuned processing.
  4. Reduced Dust Emissions: The enclosed nature of air slide systems minimizes dust emissions, enhancing workplace safety and environmental compliance.
  5. Versatility: Air slide fabric can be used for both horizontal and inclined conveying, adapting to various layout requirements.

Material Flow Control Strategies

To effectively utilize air slide fabric for material flow control, various strategies and considerations come into play:

  1. Air Pressure Adjustment: Operators can adjust the air pressure supplied to the fabric to control the speed and volume of material flow.
  2. Material Moisture Content: The moisture content of the material can impact its fluidization behavior. Understanding this relationship is crucial for precise control.
  3. Material Characteristics: Different materials exhibit varying responses to fluidization. Understanding the specific characteristics of the material being conveyed is essential for optimal control.
  4. System Design: Proper design of the air slide system, including the fabric type, slope, and length, plays a significant role in achieving the desired material flow control.

Challenges and Considerations

While air slide fabric offers numerous advantages, it is not without its challenges and considerations:

  1. Material Compatibility: Not all materials are suitable for air slide conveying. Abrasive or extremely fine materials may pose challenges.
  2. Maintenance: Regular maintenance is required to ensure the fabric’s integrity and the proper functioning of the system.
  3. Initial Investment: The installation of an air slide system involves an initial investment in equipment and infrastructure.


Air slide fabric, with its unique fluidization-based conveyor technology, offers precise and uniform material flow control across various industries. Its ability to handle materials gently, control airflow, and reduce dust emissions makes it an invaluable tool in industrial processes.

Explored the mechanics, advantages, and applications of air slide fabric in material flow control. By understanding the principles behind its operation and considering factors such as material characteristics and system design, industries can harness the benefits of air slide fabric to optimize their material handling and processing operations. Whether in cement production, food processing, or chemical manufacturing, air slide fabric proves its worth in achieving efficient and controlled material flow.
