Advantages of Conveyor Belt
High Efficiency
The conveyor belt provides efficient asphalt application, allowing rapid completion of projects and reducing labor and time costs.
Precision Work
With its precision control system, the conveyor belt can deliver asphalt with high accuracy in both coverage and thickness, improving quality and minimizing the need for rework.
Stable Operation in Harsh Conditions
The belt can handle abrasive aggregates and constant vibration, offering reliable operation on long-duration jobs and rough jobsite environments.
Consistent Paving Speed
With continuous material feeding, the paver can operate at a stable paving speed, which is essential for achieving a uniform mat thickness.
Key Components of Conveyor Belt
Chain Links
Chain links are interconnected metal segments that form a continuous loop. They are designed to withstand the hot mix asphalt material's high temperatures and abrasive nature.
Flight Bars
Flight Bars are the metal slats connected at either end to the two flight chains. These bars are what moves the material on your machine.
Sprockets
Sprockets are toothed wheels that engage with the chain links. They provide the driving force for the conveyor flight chain, causing it to move and transport the asphalt material from the hopper to the screed.
Tensioning Mechanisms
Tensioning mechanisms are responsible for maintaining the proper tension in the conveyor chain. They ensure the chain is neither loose nor tight, which is crucial for its smooth operation.
Asphalt plants deal with extreme heat. Hot mix often leaves the mixer at 150–170 °C, while polymer-modified asphalt can reach 190 °C. A normal belt cracks and hardens under these conditions. That is why belts are rated by T1–T4 heat classes:
T1: Up to 100 °C
T2: Up to 125 °C
T3: Up to 150 °C (standard hot mix asphalt)
T4: Up to 200 °C (polymer-modified and mastic asphalt)
