Air-Supported
Belt Conveyor

High-Efficiency, Eco-Friendly Long-Distance Bulk Handling

Highlights

Up to 3,000MTPH+10% throughput, single unit conveying over several kilometers
Air-cushion design: 10%–40% energy saving
Patented secondary slot angle: anti-deviation & low noise
Smooth Conveying: Zero belt bouncing and zero material spillage.

Performance Features

Trough Profile & Air Cushion System

Optimized Trough Formation: The intermediate section is engineered with tangential roller alignment to optimize belt trough formation and enhance lateral stability.
No Deviation & Low Noise: The air box section incorporates a "secondary slot angle" design, ensuring stable support to restrain belt misalignment and lower operating noise.
Fluid Friction Efficiency: Supported by an air cushion, the belt operates with fluid friction instead of rotating idlers, significantly lowering energy consumption by up to 40% and extending belt service life by 1x to 4x.

Head Section & Sealing

Comprehensive Cleaning: Equipped with a plough-type cleaner, spring-loaded head scraper, and auxiliary dust scraper at the head base to ensure complete material discharge and a clean return belt.
Advanced Gland Sealing: Precision gland packing seals prevent air and dust leakage, maintaining optimal air chamber pressure.

Air Supply & Dust Control Network

Semi-Sealed Recirculation: The integrated operation of dedicated blower units and dust collectors establishes a semi-sealed air recirculation network.
Conditioned Airflow Reuse: This network enables the efficient reuse of conditioned airflow while minimizing external environmental contamination.

Experimental Test Bench

Rigorous Test Bench Validation: Backed by rigorous testing on our specialized Air-Supported Belt Conveyor Test Bench.
Continuous Parameter Monitoring: We continuously monitor air film thickness variations under pressure and belt tensile strength to guarantee field reliability.

Applications

Ideal for efficiently transporting powdered, granular, and small lumpy bulk materials over vast distances. It performs exceptionally well in continuous horizontal conveying between ship unloaders and main silo clusters.

FAQ

How much energy can an Air-Supported Belt Conveyor really save compared to traditional roller conveyors?

Under identical capacities and process conditions, power consumption is reduced by 10% to 25% because rolling friction is replaced by fluid friction. The larger the capacity and the longer the distance, the more significant the energy savings. In actual port terminal upgrade projects, energy consumption has been reduced by up to 40%.

How is the dust emission problem solved during bulk material handling?

The conveyor features a completely sealed structural design. Dust collection vents or filters are installed at the inlet and outlet ports. Furthermore, fans and dust collectors work together to form a semi-sealed air recirculation network. This strengthens the seal between the air chamber, top cover, and head/tail connections, controlling dust spillage right from the source.

Is the equipment truly "maintenance-free"? What does routine maintenance involve?

While not strictly "zero maintenance," the maintenance workload is drastically reduced by 60% to 75% because massive numbers of rotating idlers have been eliminated. Routine maintenance is minimal: periodically inspecting air chamber orifices for blockages, cleaning blower surfaces, changing reducer oil at prescribed intervals (typically every 6 months), checking belt alignment, and replacing dust collector filter bags (typically every 2 years).
