4 Types of Aggregate Conveyors for Aggregate Handling

In modern mining and quarrying industries, the project may need to move aggregate hundreds of yards or even miles. A conveyor will save money in comparison with a fleet of trucks. Once the rock reaches the crusher, the conveyor's travel is shortened and may undergo several changes in direction or height.

After crushing and screening, the aggregate is typically stored in piles and then loaded onto barges or rail cars. Upon arrival at the destination, the aggregates are unloaded and stored again before being transferred to packaging or distribution.

4 Types of Aggregate Conveyors

MNSTACKER can provide fixed conveyors and mobile conveyors for aggregate handling in various of applications. We mainly provide 4 types of aggregate conveyors.

Overland Conveyor
Stacking Conveyor
Transferring Conveyor
Loading and unloading Conveyor

1. Overland Conveyor

The overland conveyor is a long distance conveyor which will move rock and gravel from extraction site to crushing and screening plant. The overland conveyor belt width can reach 84 inches and can move up to 6000t/h. The equipment can cross rivers and roads and adapt to complex terrain, making it a safer transportation method than trucks.

2. Stacker Conveyor

The stacker conveyor is a normal distance belt conveyor. It can be fixed or movable. The stacking conveyors are designed to lift aggregate in site of stockyard of aggregate plant. This is do to build storage piles that may be needed after crushing and screening. There are mainly 4 types of aggregate stacking conveyors.

Fixed belt stacker conveyor in fixed stone crushing plant (0~6000t/h).
Tracked mobile conveyor for mobile crushing plant (0~500t/h).
Radial stacker for large stockpile volume in mobile plant or fixed plant (0~4500t/h).
Tripper conveyor for aggregate stockpiling (0~6000t/h).

Aggregate Radial Stacker Conveyor

Our radial stacking conveyors are often radial in design, meaning they can pivot or rotate. This allows the creation of a larger aggregate pile. They may also be telescopic so aggregate can be deposited in an even larger pile, or they can be portable.

3. Transfer Conveyor

While overland conveyors can follow terrain, changing direction requires a very large radius. If there is insufficient space, for example during the loading or unloading phase, the solution for direction changes is a transfer conveyor. These are also used to accommodate rapid elevation changes. They are easier to transfer from one project to another. Our grasshopper conveyor can be one of your best choices.

Length: 12m to 45m, and more length.
Capacity: 0~2000t/h, and more capacity.
Moving: tracked or wheeled, manual moving and self-propelled.

4. Loading and Unloading Conveyor

Loading and unloading conveyors are typically short and inclined. Their main applications are raising aggregate so it can waterfall into railcar or barges, or taking it from the underside of railcar and raising it to fill trucks or to move it into storage.

Bulk Material Reception Feeder: Unloading aggregate from railcar, trucks and barges.
Mobile Hopper Feeder: Feeding next processing machine or loading rail car and barges.
Mobile Shiploader: Loading ships from barges to Cape-size Ships.

Our mobile shiploaders are developed from radial telescopic stockpiler. Portable designs are also available and it can be tracked or all wheel travel. Our bulk material reception feeder are fixed, wheeled or tracked. Our mobile hopper feeder can be tracked or wheeled.

Designs of Aggregate Conveyors

The belt and motor/drive system must be sized for the load on the fully loaded belt. Consideration should also be given to the type of tightening device and motor coupling used.

Aggregate hauling operations are inherently dusty, which can damage bearings (such as those used in idlers). Therefore, the design of the conveyor system should consider preventing the ingress of dust.

When designing a radial stacking or loading conveyor, the maximum rotational speed should be determined by the conveyor size and peak load. Speeds that are too high may result in unstable operation.

Components of Aggregate Conveyors

Belts: fabric or steel cord rubber belt.
Cleaner: belt scraper and v plow cleaner.
Drives: geared motor or gear box plus motor and coupling.
Pulley: drum pulley and wing pulley and motorized pulley.
Idler Rollers: steel idler roller, HDPE roller and UHMWPE roller.
Covers: lacquered steel, galvanized, stainless steel and fiber glass.
Loading chute: fall free or cascade loading spouts.
Moving: undercarriage with tracks or wheels.

MNSTACKER will custom-design an aggregate conveyor system that solves dust, abrasive material, and influence transfer rate challenges. We’ll optimize the drive system, belt construction, structure, and dust control components. This will help ensure your new conveyor system saves time and money while adding significant value to your aggregate operations.
