Belt conveyors are a fundamental part of the aggregate production industry, providing efficient, cost-effective, and environmentally friendly transportation of raw materials such as sand, gravel, crushed stone, and minerals. These conveyors help streamline operations by reducing manual handling, increasing productivity, and minimizing material loss.
Belt Conveyor For Aggregate Production
The Key Components of belt conveyors for aggregate production line.
- Conveyor Belt: Made from rubber, fabric, or steel-reinforced materials to handle heavy loads. Multi-ply fabric conveyor belts is ideal for standard aggregate handling. Steel-cord reinforced belts are suitable for long-distance or high-tension applications of transportation for aggregate production line. Chevron belts are designed for steep inclines and better grip on loose materials.
- Rollers & Idlers: Support the belt and minimize friction. Our carrying idlers are positioned along the conveyor length to support the loaded belt and reduce sagging. Our return idlers are support the empty return belt, maintaining alignment. Our Impact Idlers are placed at loading points to absorb shock and prevent belt damage.
- Drive System (Motors & Gearboxes): Provides power to move the belt.
- Pulleys: Guide and control belt movement. We provide drive pulleys and bend pulleys for belt conveyor used in aggregate production line. These drum pulleys can be diamond rubber lagged or ceramics rubber lagged.
- Support Structure: Ensures stability and alignment. The robust steel frame can provide structural support for the belt and components.
- Control Systems: Our belt conveyor control system can include Speed Control & Flow Automation, Overload & Misalignment Detectors, Emergency Stop & Safety Pull Cords, Weighing & Monitoring Systems, Dust Suppression Systems, etc.
Common Types in Aggregate Production
- Stationary Belt Conveyors: The fixed belt conveyor is fixed in place for continuous operations. It is ideal for long-term aggregate production plants.
- Portable Belt Conveyors: Our portable belt conveyors are suitable for temporary projects. They are used in road construction, mining, and small-scale aggregate production.
- Radial Stacker Conveyors: Our radial stacker is equipped with a rotating boom for stockpile formation. It can be designed with telescopic booms. Our radial stacker and radial telescopic stacker can reduce the need for loaders and optimizes storage space.
- Overland Conveyors: Our long distance conveyors for transporting aggregates over rough terrains and this type of belt conveyors reduces fuel consumption and operational costs compared to trucks.

Belt Conveyor For Aggregate Production
A belt conveyor is a continuous material transport system consisting of a moving belt supported by rollers and driven by a motorized pulley system. It efficiently moves aggregates from one processing stage to another, reducing reliance on trucks or loaders. The below is working principle of belt conveyors for aggregate production line.
Loading
Aggregates are placed onto the conveyor belt through hoppers, front-end loaders, grab cranes, excavators, or truck dump stations, depending on the site configuration. Use of vibrating feeders, apron feeders, or weigh belt feeders ensures a consistent feed rate, preventing material surges and optimizing production efficiency. Side skirts, enclosed transfer points, and dust suppression systems contain material within the belt width, reducing material loss and airborne dust emissions.
Transport
The conveyor belt moves over precisely spaced idlers and rollers, minimizing friction and ensuring smooth transportation. The belt is made from reinforced rubber, fabric, or steel-cord materials to withstand the impact and abrasion of aggregates. The belt is driven by electric or hydraulic motors, with variable frequency drives (VFDs) allowing speed adjustments for optimized material flow. Self-aligning idlers, belt scrapers, and emergency stop switches enhance reliability, reduce downtime, and improve safety.
Discharge
At the discharge end, aggregates are directed onto stockpiles, processing units (such as crushers or screens), trucks, or rail wagons with minimal spillage. Radial stackers enable even distribution of stockpiles. Telescopic conveyors provide flexible reach and height adjustments for efficient unloading. Tripper conveyors distribute materials at multiple drop points. Incorporation of belt plows, chutes, or diverter gates allows for precise control over the discharge process, reducing wastage and improving site efficiency.
