Air slide belt is a specialized air-permeable fabric designed for pneumatic conveying systems. It is widely used in air slide conveyors to transport dry powder materials through controlled airflow. Acting as a permeable membrane between the air chamber and the material layer, the belt allows uniform air distribution, enabling smooth and energy-efficient material flow.
Description
Our products have good dimensional stability and excellent mechanical strength, which can meet the long-term stable operation requirements of continuous industrial production.
Air slide belts are constructed with 2-ply, 3-ply, or 4-ply fabric layers. High tear-resistant, heat-resistant, and abrasion-resistant fibers provide excellent conveying performance and operational stability. The belt is capable of withstanding severe conditions including high temperatures, contact pressure, friction, tensile stress, and humidity. This ensures safety, stability, and reliability throughout the production process.
Post-processing
- Edge Reinforcement: Trim and reinforce the edges to prevent cracking and ensure uniform operating tension.
- Surface Treatment: Silicone coating, antistatic treatment, or heat treatment can be applied to improve abrasion resistance, moisture resistance, or air distribution control performance.

Application Scenarios
- Air Slide Conveyor Systems
Widely used in pneumatic conveying trough systems for horizontal or inclined transportation of fine powder materials such as cement, raw meal powder, fly ash, alumina powder, pulverized coal, lime, gypsum powder, and other bulk powders. The air slide belt serves as a permeable membrane, enabling smooth and energy-efficient material flow while minimizing dust leakage and mechanical wear.
- Silo / Hopper Aeration & Discharge Systems
Installed in silos or storage bins to improve powder fluidity and prevent arching, bridging, and rat-holing during discharge. By providing uniform air distribution, the air slide belt enhances unloading efficiency, ensures consistent material flow, and reduces residual buildup inside the silo.
- Fluidized Beds & Mixing Equipment
Used as a breathable base layer in fluidization systems, blending equipment, and homogenizing units. It allows controlled airflow distribution, facilitating stable powder fluidization, uniform mixing, and improved processing performance in industrial production environments.
