Air slide conveyors are essential for moving dry powders like cement and fly ash efficiently. Learn how an air slide works, its main components, and why cement plants rely on this system for reliable, low-energy transportation.
What Is an Air Slide Conveyor?
An air slide conveyor is a highly efficient pneumatic conveying system used for transporting dry powder materials such as cement, fly ash, alumina, and other fine particles. It operates without mechanical moving parts, making it one of the most reliable and energy-saving conveying methods in cement and industrial plants.
The system uses a low-pressure air supply to fluidize the material, allowing it to flow smoothly through a specially designed trough lined with air-permeable fabric.
How an Air Slide Conveyor Works
The air slide consists of two chambers separated by an air slide fabric.
Once compressed air is introduced into the lower chamber:
- The powder becomes fluidized
- Material begins to flow toward the discharge point
- No mechanical wear occurs
- Energy consumption remains extremely low
This simple yet effective mechanism allows continuous, dust-free conveying over long distances.
Main Components of an Air Slide System
Your photo shows standard air slide trough sections, which are essential components of the complete air slide system. Below are the key parts:
1. Air Slide Trough (Galvanized or Carbon Steel)
- Modular structure for easy installation
- Precision-bolted flanges ensure a dust-tight seal
- Strong, durable steel body suitable for heavy-duty industrial use
2. Air Slide Fabric / Media (Polyester or Aramid)
- High air permeability
- Heat resistant (up to 180°C)
- Long service life with consistent performance
3. Support Frame & Grating
- Located inside the trough
- Ensures stable support for the fabric
- Allows uniform air distribution
4. Air Supply System
- Roots blower or centrifugal fan
- Complete with air filters, valves, and pipelines
5. Discharge & Control Equipment
- Rotary valves
- Flow control valves
- Dust collection connections
These components work together to form a stable, continuous conveying system.
Benefits of Air Slide Conveyors
✅ Energy Efficient
Uses very low-pressure air; energy consumption is extremely low.
✅ No Mechanical Wear
No chains, belts, or motors inside the conveyor—minimum maintenance needed.
✅ Dust-Free Operation
Fully enclosed design prevents dust leakage and ensures a clean working environment.
✅ Long Service Life
Air slide fabric and trough modules are durable and easy to replace.
✅ Stable Conveying for Cement Plants
Ideal for transporting materials such as:
- Cement
- Clinker dust
- Fly ash
- Limestone powder
- Alumina
Applications in Cement & Industrial Plants
Air slide conveyors are widely used in:
- Cement grinding units
- Silo feeding and discharge
- Packing plants
- Bulk loading systems
- Fly ash and alumina processing industries
The system is especially suitable for long-distance horizontal conveying with low maintenance requirements.
