In the world of material handling and conveyor systems, efficiency, reliability, and cost-effectiveness are paramount. Two commonly used methods for transporting bulk materials within industrial settings are the air slide fabric conveyor and the gravity conveyor.

what is Air Slide Fabric Conveyor

Air slide fabric conveyors, often referred to as aeration conveyors, are a unique and versatile solution for handling powdered or granular materials. They rely on the principles of fluidization to transport materials using a flow of air within a porous fabric.

Top 5 Advantages of Air Slide Fabric Conveyor

  1. Gentle Material Handling: Air slide fabric conveyors offer gentle handling of materials, making them suitable for delicate or friable substances, such as flour, cement, and powders.
  2. Low Maintenance: These conveyors have relatively low maintenance requirements due to the absence of moving mechanical parts, reducing the risk of breakdowns.
  3. Uniform Flow: Air slide fabric conveyors ensure a consistent and uniform flow of materials, minimizing segregation and promoting homogeneity.
  4. Versatility: They can transport materials horizontally or vertically and can be easily integrated into existing conveyor systems.
  5. Dust Control: Air slide fabric conveyors are effective in controlling dust emissions, promoting a cleaner and safer working environment.

what is Gravity Conveyor

Gravity conveyors are a simpler and cost-effective solution for material transport. They rely on the force of gravity to move materials along a declining or sloped surface, usually a roller or skatewheel conveyor.

Top 5 Advantages of Gravity Conveyor

  1. Cost-Effective: Gravity conveyors are typically more affordable to install and maintain than complex mechanical systems.
  2. No Power Requirement: They do not require electricity or a power source, reducing energy consumption and operational costs.
  3. Quiet Operation: Gravity conveyors operate quietly, making them suitable for environments where noise pollution is a concern.
  4. Ideal for Accumulation: They are excellent for accumulating products in a queue or for temporary storage before further processing.
  5. Easy to Install: Gravity conveyors are relatively easy to install and reconfigure, offering flexibility in layout design.

The respective applications of pneumatic slide rail distribution conveyors and gravity conveyors

Air Slide Fabric Conveyor Applications:

  • Cement Industry: Used for the transportation of cement powder within production facilities.
  • Food Industry: Ideal for handling flour, sugar, and other powdered ingredients.
  • Chemical Industry: Suitable for conveying powders and granules in chemical processing plants.
  • Bulk Material Handling: Applicable in various industries for the gentle transport of bulk materials.

Gravity Conveyor Applications:

  • Distribution Centers: Gravity conveyors are commonly used in distribution centers for order picking and shipping.
  • Manufacturing: Ideal for moving products from one stage of production to another.
  • Warehousing: Used for simple material flow, accumulation, and sorting in warehouses.
  • Assembly Lines: Gravity conveyors facilitate the assembly of products in manufacturing lines.

Considerations for Selection

When choosing between an air slide fabric conveyor and a gravity conveyor, consider the following factors:

  • Material Characteristics: Determine the nature of the materials you need to transport, as this will greatly influence your choice.
  • Space and Layout: Consider the available space and layout of your facility, as well as the desired flow direction.
  • Operational Requirements: Assess the need for precise material control, dust control, and the overall operational goals.
  • Budget: Evaluate your budget constraints, as air slide fabric conveyors may require a more substantial initial investment.


The choice between an air slide fabric conveyor and a gravity conveyor depends on the specific requirements of your material handling application. Air slide fabric conveyors offer gentle handling and are ideal for powdered or granular materials with minimal maintenance needs. Gravity conveyors, on the other hand, are cost-effective and versatile for bulk transportation of various items.

By carefully evaluating your material characteristics, space constraints, operational goals, and budget, you can make an informed decision and select the conveyor system that best suits your needs. Both options have their advantages and applications, and choosing the right one will contribute to the efficiency and success of your material handling operations.
