Air Slide – Efficient Pneumatic Conveying System for Powder Material

An Air Slide is a continuous conveying equipment designed for the horizontal or slightly inclined transportation of dry, fine and powdery bulk materials. By introducing low-pressure air through a porous aeration fabric, the material becomes fluidized and moves smoothly along the conveying chute.

Compared with traditional mechanical conveyors, an Air Slide has no chains, belts, buckets or rotating conveying parts inside the material conveying area. This simple operating principle makes it an efficient and reliable solution for powder material handling.

The Air Slide is widely used in cement plants, mineral processing plants, chemical plants, power plants, lime plants and other industries where large quantities of dry powder materials need to be transported continuously.

How Does an Air Slide Work?

The Air Slide consists mainly of an upper conveying chamber, aeration fabric, lower air chamber, inlet, outlet, inspection openings and supporting structure.

During operation, low-pressure air enters the lower air chamber through an air supply system. The air passes evenly through the aeration fabric and fluidizes the powder material above it.

After fluidization, the material behaves similarly to a flowing fluid and moves from the higher end toward the lower end under gravity and the conveying chute's inclination.

This conveying method creates a gentle and continuous material flow while reducing mechanical wear, dust generation and maintenance requirements.

What Problems Can an Air Slide Solve?

Powder materials can be difficult to handle because they may generate dust, bridge inside equipment, or cause excessive wear during mechanical conveying.

An Air Slide provides an effective solution for these problems. Its enclosed conveying structure helps reduce material leakage and dust emissions. The absence of rotating conveying components also reduces mechanical wear and maintenance requirements.

For cement, fly ash, raw meal, mineral powder and other dry bulk materials, an Air Slide can provide stable continuous conveying over relatively long conveying routes.

Key Advantages of Our Air Slide

1. Efficient Powder Conveying

The fluidized conveying principle allows dry powder materials to move smoothly and continuously. It is particularly suitable for fine materials with good fluidity.

2. Low Energy Consumption

The Air Slide uses low-pressure air rather than a large mechanical drive system. Under suitable operating conditions, this can reduce the energy consumption of the conveying process.

3. Simple Structure

Compared with mechanical conveyors, the Air Slide has fewer moving parts. The simple structure helps reduce equipment failure and makes routine maintenance easier.

4. Low Maintenance Cost

There are no internal chains, belts or scraper mechanisms that require frequent lubrication and replacement. The main wear components are the aeration fabric and sealing components.

5. Enclosed Conveying

The enclosed chute structure helps minimize material spillage and dust leakage, making the Air Slide suitable for modern clean production systems.

6. Gentle Material Handling

The fluidized conveying process causes relatively little mechanical impact on the material. It is suitable for applications where stable powder transportation is required.

7. Flexible Installation

The Air Slide can be designed according to the material characteristics, conveying capacity, conveying distance and installation conditions. Horizontal and inclined conveying arrangements are available.

Technical Parameters of Air Slide

Technical specifications can be customized according to material characteristics and project requirements.

Air Slide Applications

Cement Industry

Air Slide systems are commonly used for conveying cement, raw meal, fly ash, clinker dust and other fine powder materials. They can be integrated into grinding, storage, batching and packing systems.

Mining and Mineral Processing

In mineral processing plants, an Air Slide can be used to transport dry mineral powders and fine concentrates between storage, processing and feeding equipment.

Power Plants

The system can be applied to the conveying of dry fly ash and other powder materials, especially where enclosed and continuous conveying is required.

Chemical Industry

For suitable dry powder chemicals, Air Slide equipment can provide stable and enclosed material transportation.

Building Materials Industry

Lime powder, cementitious materials, mineral powder and other fine dry materials can be conveyed through an Air Slide system.

Air Slide vs. Mechanical Conveyor

An Air Slide and a mechanical conveyor use different conveying principles.

A mechanical conveyor normally relies on belts, screws, chains or other moving components to transport materials. An Air Slide uses low-pressure air and gravity to fluidize and move powder materials.

Therefore, an Air Slide is particularly advantageous for dry, fine and easily fluidized powders. It offers a simple structure, low maintenance requirements and enclosed conveying.

For coarse, wet, sticky or poorly fluidized materials, however, other conveying technologies may be more appropriate.

Frequently Asked Questions

What materials can an Air Slide convey?

An Air Slide is mainly designed for dry, fine and powdery materials with suitable fluidization characteristics, such as cement, fly ash, raw meal and mineral powder.

Does an Air Slide require a motor?

The conveying chute itself normally does not require a mechanical conveying motor. It relies on low-pressure air and gravity. However, the complete system requires an air supply device such as a blower.

Is an Air Slide suitable for inclined conveying?

Yes. An Air Slide can be installed horizontally or at a suitable inclination. The installation angle should be selected according to the material properties and required conveying capacity.

How can Air Slide capacity be determined?

Capacity depends on material properties, chute width, inclination, conveying distance, aeration conditions and system design. The final capacity should be determined according to the specific project.

Can the Air Slide be customized?

Yes. The chute dimensions, conveying length, inclination, inlet and outlet arrangement, materials and air supply configuration can be customized according to customer requirements.

Conclusion

The Air Slide is an efficient pneumatic conveying solution for dry powder materials. With its fluidized conveying principle, enclosed structure, simple design and low maintenance requirements, it is an ideal choice for continuous powder transportation in cement, mining, chemical, power and building material industries.
