Description
Introduction:
A Trough Belt Conveyor is a heavy-duty bulk material handling system designed to transport loose, granular, or powdered materials efficiently over long distances. Unlike flat belt conveyors, a trough belt conveyor uses specially arranged idler rollers to form the belt into a trough shape, which helps contain materials and prevent spillage during conveying.
Trough belt conveyors are widely used in industries such as mining, cement, power plants, steel plants, ports, and bulk material processing units. At Tech Trek Engineering, we manufacture robust and reliable trough belt conveyors that are engineered for high capacity, continuous operation, and demanding industrial environments.
What is a Trough Belt Conveyor?
A trough belt conveyor is a belt conveyor system in which the belt is supported by troughing idlers that shape the belt into a U-like profile. This trough shape increases material carrying capacity and ensures stable transportation of bulk materials.
The system consists of a continuous belt, head and tail pulleys, troughing idlers, return idlers, a drive unit, and a rigid supporting structure. The conveyor can be designed for horizontal, inclined, or slightly declined applications.
Working Principle:
The working principle of a trough belt conveyor is as follows:
- The drive motor rotates the head pulley through a gearbox.
- The belt moves forward over troughing idlers, forming a trough shape.
- Bulk material is loaded onto the belt at the feed point.
- The trough shape holds the material securely during transportation.
- The material is discharged at the head end through gravity or discharge chutes.
- The empty belt returns on return idlers underneath the conveyor structure.
This design allows continuous, high-capacity material handling with minimal loss.
Key Features of Trough Belt Conveyor:
- High material carrying capacity
- Designed for bulk and abrasive materials
- Reduced spillage due to trough profile
- Suitable for long-distance conveying
- Strong and durable structure
- Smooth and continuous operation
- Low operating cost per ton of material
- Designed for outdoor and indoor use
Troughing Angle Options:
The troughing angle plays a critical role in conveyor capacity and material stability. Common options include:
- 20° trough angle
- 30° trough angle
- 35° trough angle
- 45° trough angle (for special applications)
The selection depends on material flow characteristics, belt width, and capacity requirement.
