Air Gravity Conveyor System for Dry Bulk Powders
(Konveyor Air Slide – Sistem Konveyor Gravitasi Udara)
Efficient air slide conveyor for cement, fly ash, and other fine bulk powder materials
Overview
The air slide conveyor is a gravity-based powder conveying system that uses low-pressure air to fluidize dry bulk materials. It is commonly installed between silos, hoppers, packing machines, and bulk loading stations, offering energy-efficient and dust-free material transport without moving mechanical parts.
Air slide conveyors are widely used between silos, packing machines, bulk loading stations, and kiln feeding systems for powder materials such as cement, fly ash, and lime. With no moving parts and fully sealed construction, the system ensures dust-free conveying, low power consumption, and minimal maintenance.
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 gravity conveyor operate based on a simple but reliable principle:
✅ 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, and minimal wear
This air fluidization conveying principle ensures smooth, low-energy, and maintenance-free transport of dry bulk powders.
This fluidization process is widely used in cement, minerals, and chemical industries due to its stable performance and very low mechanical wear.
Features
✅ Simple structure, no rotating parts
✅ Low maintenance and long service life
✅ Completely sealed and dust-free operation
✅ Supports multiple outlets and diverters
✅ Suitable for high-temperature and abrasive powders
✅ Smooth and continuous material flow
LVRUI air slide conveying system are compatible with multiple outlets, diverters, rotary feeders, and flow control gates, allowing efficient integration into existing powder conveying and bulk loading systems.
Air slide conveyors are especially suitable for continuous powder flow in cement plants, fly ash handling systems, and bulk material transfer lines.

Air slide conveyors are widely used in cement plants, fly ash terminals, silo feeding and discharge systems, packing lines, and bulk powder handling facilities. They provide stable and continuous powder conveying with minimal energy consumption and mechanical wear.
Applications
Air Slide Conveyors are widely applied in:
✅ Cement plants and cement grinding systems
✅ Fly ash terminals and fly ash handling systems
✅ Silo feeding and discharge lines
✅ Packing and bulk loading systems
✅ Pneumatic and hybrid bulk powder conveying systems
Air slide conveyors are essential in cement grinding stations, fly ash terminals, bulk powder depots, kiln feeding lines, and pneumatic conveying systems. They ensure stable and continuous powder flow without mechanical wear.
For dust-free bulk loading operations, the Dust-Free Loading Spout is commonly integrated with air slide conveyors to minimize material loss and environmental pollution.
FAQs About Air Slide Conveyor
What materials are suitable for an air slide conveyor?
Air slide conveyors are suitable for dry, fine, and free-flowing powders such as cement, fly ash, lime powder, and other bulk powders that can be fluidized by air.
What is the difference between an air slide conveyor and a pneumatic conveyor?
An air slide conveyor uses gravity and low-pressure air for material transport, while pneumatic conveyors rely on high-pressure air and pipelines. Air slide systems are more energy-efficient for short to medium distances.
Does an air slide conveyor require moving mechanical parts?
No. Air slide conveyors have no rotating or moving conveying parts, resulting in low maintenance and long service life.
Can air slide conveyors be integrated into bulk loading systems?
Yes. Air slide conveyors are commonly integrated with silos, packing machines, and bulk loading systems for continuous powder transfer.
What is the difference between an air slide conveying system and a screw conveyor?
An air slide conveying system uses air fluidization and gravity for powder transport, while a screw conveyor relies on mechanical rotation. Air slide conveyors are more energy-efficient and wear-free for fine dry powders such as cement and fly ash.
