Belt Conveyors for Sugarcane and Sorghum Cane
Belt Conveyors for Sugarcane and Sorghum Cane


Air is supplied by a small, low power centrifugal fan and is blown into a sealed plenum, where it passes through a row of small holes at the bottom of the trough. This creates a thin supporting film of air between the belt and trough. A single fan will supply 200 meters of conveyor. Pressure is typically 4 to 5 Kpa and volume is approximately 0.5m³ per minute per meter length of system.  Plenums can be supplied in mild steel, 3CR12, 304/316 SS or aluminum.

Virtually No Maintenance - No troughing rollers to replace or lubricate.

Steeper Slope Characteristics (up to 26°) - Means better utilization of available space and shorter belt lengths. 
Longer Unsupported Spans - High beam strength is inherent in the design due to the box girder construction of the plenum. Due to longer unsupported spans, installation of air supported belt conveyors can significantly reduce erection costs. Typically up to 50% lower than conventional belt conveyors.
Environmentally Friendly - Far less noise pollution than conventional troughing conveyors. 
Walkways Eliminated - Air supported belt conveyors have no load-bearing idlers and only routine maintenance is required to inspect and replace return idlers.  Most installations do not require walkways although they are available when requested.
No Tracking Problems - and higher belt speeds up to 5 meters per second can be achieved with air supported belt conveyors without damage to product or belt.
Lighter Belting - Because the load-bearing length of the belt is continually supported on an air cushion, it is not subjected to the same stresses as belts on a conventional conveyor. Therefore, the air supported belt conveyors operate with thinner, lower tension belts. Significant reduction in belt friction also allows for much longer belt life and lower total energy consumption
