（ID）Panduan Mudah dan Jelas untuk Memahami Cara Kerja Air Slide Conveyor
Introduction
When handling fine powder materials such as cement, fly ash, clinker dust, and lime powder, an Air Slide Conveyor (Air Gravity Conveyor) is one of the simplest and most efficient conveying technologies in the bulk material handling industry.
This guide explains how an air slide works, its structure, applications, advantages, and how to select the right air slide for your plant.
What Is an Air Slide Conveyor?
An Air Slide Conveyor is a gravity-based conveying system that uses a flow of low-pressure air through a permeable fabric to move powdered materials horizontally or slightly downward.
When air passes through the fabric, the powder becomes fluidized—behaving almost like a liquid—and flows smoothly along the conveyor channel.
📌 Air Slide = No moving parts + low energy + continuous flow.
How Does an Air Slide Conveyor Work?
An air slide system consists of:
- A steel trough (upper and lower chambers)
- Air slide fabric (permeable membrane)
- Low-pressure blower
- Inlet/outlet chutes
- Inspection covers
Working Principle:
- Air enters the lower chamber from a blower
- Air flows upward through the air slide fabric
- Powder above the fabric becomes fluidized
- Gravity moves the fluidized material along the slope (5–12°)

How to Select the Right Air Slide Conveyor
Cara Memilih Air Slide Conveyor yang Tepat
When designing or selecting an air slide system, consider:
✔ 1. Material type & particle size
Cement, fly ash, clinker dust require different fabric permeability.
✔ 2. Temperature of material
High-temp materials need heat-resistant fabric.
✔ 3. Length & slope
Standard slope ranges from 5°–12°.
✔ 4. Blower capacity
Correct airflow ensures stable fluidization.
✔ 5. Fabric type
Polyester → economical
Aramid → high temp
P84 → premium, longest lifespan
⭐ Air Slide Conveyor vs Screw Conveyor
| Feature | Air Slide | Screw Conveyor |
|---|---|---|
| Moving Parts | ❌ None | ✔ Yes |
| Maintenance | Low | High |
| Dust Control | Excellent | Medium |
| Energy Consumption | Very low | Medium–High |
| Best For | Powder | Mixed materials |
Conclusion:
If your system handles powders, air slide is always more efficient.
