Airslide is an efficient pneumatic conveying system used to transport dry powdered materials, such as cement, chemicals, and fly ash. It offers several advantages over traditional conveying systems, including low power consumption, low maintenance, and minimal dust emission.

Working Principle

At the core of an airslide system is the fluidization bed, which consists of a porous membrane that separates two chambers. The top chamber is where the material to be conveyed is loaded, while the bottom chamber is connected to a system of air blowers and filters.

When the air is blown into the bottom chamber, it passes through the porous membrane and creates channels of low resistance within the fluidized bed. The pressure differential created between the top and bottom chambers forces the material to move along these channels, resulting in a continuous flow of material through the airslide.

Top 3 Applications of airslides

Airslides are commonly used in various industries where there is a need for efficient and reliable transportation of powdered materials. Some of the primary applications of airslides include:

Cement Industry

Airslides are extensively used in the cement industry for conveying cement from the storage silos to the packing machines. The low power consumption and minimal dust emission make airslides an ideal solution for cement plants.

Chemical Industry

In the chemical industry, airslides are used to transport a wide range of dry powdered materials, such as detergents, dyes, and pigments. The gentle conveying mechanism of airslides helps prevent materials from breaking down or becoming contaminated during transportation.

Power Plants

In power plants, fly ash is generated as a by-product of burning coal. Airslides are commonly used to transport fly ash from power plants to cement plants, where it is used as one of the raw materials to produce cement. The use of airslides for transporting fly ash is highly efficient and reduces the environmental impact of coal-based power plants.

Advantages of Airslide Fabric in comparison with Traditional Conveyor Belts

Top 4 advantages of using airslides in material conveying systems

  • Low power consumption: Airslides require minimal power to operate, making them energy-efficient and cost-effective.
  • Low maintenance: Airslides have a simple design and require minimal maintenance, resulting in low operating costs.
  • Minimal dust emission: The use of airslides results in minimal dust emission, ensuring a safer and cleaner working environment.
  • Gentle conveying mechanism: The gentle conveying mechanism of airslides helps prevent degradation and contamination of materials during transportation.


While airslide fabric offer significant advantages, they also have some limitations that must be considered:

  • Limited for certain materials: Airslides are not suitable for all materials, such as those that may become clogged or that are too heavy to be conveyed by air.
  • Limited distance: Airslides have limited distance capabilities as the pressure differential required to move the material diminishes with increased distance.
  • Need for clean air: Airslides require clean air to operate efficiently. Too much moisture or dust in the air can clog the airslide and reduce its effectiveness.


Airslide fabric are an efficient and cost-effective solution for transporting dry powdered materials in various industries. The simple design, low power consumption, and minimal maintenance of airslides make them an ideal choice for companies looking to streamline their conveying systems and reduce their environmental impact.
