Sistem Konveyor Air Slide untuk Semen, Fly Ash, Kapur, dan Bubuk Halus
Overview
Air Slide Conveyor is a low-pressure fluidized conveying system designed for smooth, dust-free, and energy-efficient transfer of dry fine powders in cement plants and bulk material handling systems. LVRUI air slide conveyor systems are widely used for cement silo discharge, fly ash transfer, lime powder conveying, grinding station material transport, and bulk loading line integration. With no moving parts inside the conveying chamber, the system offers low maintenance, stable operation, and long service life for continuous industrial powder handling.
Applications include:
✅ Cement silo discharge systems
✅ Grinding station transfer lines
✅ Bulk loading and unloading systems
✅ Fly ash handling terminals
✅ Lime transfer lines and other mineral powders
For dust-free bulk loading solutions, see our Cement Bulk Loader .
Air slide systems meet global dust emission guidelines, including compliance with U.S. EPA standards for industrial air quality and dust control.
Working Principle
Air slide conveyors operate on air fluidization and gravity, providing gentle material transport with no moving mechanical parts.
✅ Compressed air enters the chamber under the porous fabric
✅ Powder becomes fluidized and flows like liquid
✅ Material is transported gently along the slope
✅ No friction, low noise, minimal wear
Compared with screw or pneumatic conveyors, air slide conveyor systems are highly energy-efficient for short- to medium-distance bulk powder transport.
For smooth and controlled material flow, use our LVRUI Flow Control Gate for Silo Discharge, designed for cement and bulk powder handling systems.

How to Select the Right Air Slide Conveyor for Your Project
To select the right air slide conveyor, engineers should consider material type, bulk density, moisture content, required capacity, conveying distance, chute angle, air pressure, installation space, inlet position, outlet quantity, and dust collection requirements. For cement plants, the most common selection factors are conveying capacity, slope angle, air slide fabric quality, sealing performance, and integration with silo discharge or bulk loading equipment.
| Selection Factor | Why It Matters |
|---|---|
| Material type | Cement, fly ash, lime, and mineral powder have different fluidization behavior |
| Required capacity | Determines slide width, chute size, and air volume |
| Conveying distance | Affects system layout and air distribution |
| Chute angle | Usually 4°–12°, depending on material flowability |
| Moisture content | Wet or sticky powder may cause blockage |
| Air supply | Stable low-pressure air is required for fluidization |
| Outlet design | Single-point or multi-point discharge requires different layouts |
| Dust control | Sealed structure and dust collector connection improve site cleanliness |
Suitable Materials for Air Slide Conveyor Systems
Air slide conveyor systems are suitable for dry, fine, and free-flowing powders. They are not recommended for wet, sticky, coarse, lumpy, or irregular granular materials. For materials with poor flowability, moisture, or lumps, additional equipment such as aeration pads, lump breakers, or flow control gates may be required.
| Suitable Materials | Not Recommended |
|---|---|
| Cement powder | Wet powder |
| Fly ash | Sticky material |
| Lime powder | Large lumps |
| Raw meal | Coarse aggregate |
| Mineral fines | High-moisture material |
| Fine dry powder | Irregular granular material |
Applications & Use Cases
Air slide conveyor systems are ideal for:
✅ Transporting dry, fine, free-flowing powders such as cement, fly ash, lime, and mineral powders
✅ Fly ash handling and transfer in bulk storage terminals
✅ Silo discharge and stable powder flow for grinding stations
✅ Bulk loading and unloading for cement and related powders
✅ Integration with packing lines and aeration systems
FAQs About Air Slide Conveyor Systems
What is this conveying system used for in cement plants?
This conveying system is mainly used to transfer dry fine powders such as cement, fly ash, lime powder, and raw meal between silos, grinding stations, packing lines, dust collectors, and bulk loading systems. It provides smooth, enclosed, and low-maintenance powder transfer for cement and mineral processing plants.
How does an air slide conveyor work?
An air slide conveyor works by sending low-pressure air through a permeable air slide fabric. The powder above the fabric becomes fluidized and flows along the inclined chute by gravity. This design allows continuous powder transport without rotating parts inside the conveying chamber.
What materials are suitable for an air slide conveyor system?
This system is suitable for dry, fine, and free-flowing powders, including cement, fly ash, lime powder, raw meal, mineral powder, and similar bulk materials. Wet, sticky, lumpy, or coarse materials are not recommended because they may cause poor flow or blockage.
What is the difference between an air slide conveyor and a pneumatic conveyor?
An air slide conveyor uses low-pressure air and gravity to move powder along an inclined chute, while a pneumatic conveyor uses air pressure to push or pull material through pipelines. Air slide conveyors are usually more energy-efficient for short- to medium-distance cement and powder transfer.
What is the difference between an air slide conveyor and a screw conveyor?
An air slide conveyor has no moving parts inside the conveying chamber and is suitable for dust-free fine powder transfer. A screw conveyor uses a rotating screw shaft and is better for controlled feeding or layouts where gravity flow is not available.
How do I choose the right air slide conveyor capacity?
Capacity depends on slide width, chute angle, material bulk density, moisture content, air volume, conveying distance, and outlet design. For cement plants, common model options include AS200, AS250, AS315, AS400, AS500, AS630, and AS800.
Can an air slide conveyor be used for cement silo discharge?
Yes. It is widely used for cement silo discharge, fly ash silo discharge, grinding station transfer, and bulk loading line feeding. It can also be combined with flow control gates, aeration pads, diverter gates, and dust collectors to build a complete powder handling line.
How long does the system last?
With proper air supply, regular inspection, clean fabric, and suitable material conditions, the system can operate reliably for many years. The actual service life depends on powder abrasiveness, operating hours, fabric quality, sealing performance, and maintenance practice.
