A mobile belt conveyor is a type of continuous conveying and loading/unloading equipment equipped with wheels, allowing it to be repositioned freely. Unlike traditional stationary belt conveyors, it does not require a permanent concrete foundation; the entire unit can be relocated to different work sites as needed. It is widely used in locations requiring frequent changes in operating positions, such as ports, terminals, railway stations, coal yards, mines, warehouses, construction sites, sand and gravel yards, and farms.
The operating principle of a mobile belt conveyor is straightforward. An electric motor drives the head pulley to rotate, using the friction between the pulley and the conveyor belt to pull the belt in a continuous loop. The belt travels around the head and tail pulleys to form a closed circuit; supported by upper and lower idlers, it serves as both the load-bearing and traction component.
Material is fed from a hopper onto the belt and moves at a constant speed toward the discharge end, where it is automatically unloaded by gravity. The equipment supports horizontal, inclined (upward), and declined (downward) conveying modes. For models longer than 10 meters, the conveying angle can be adjusted according to specific requirements.
The unit is equipped with wheels at the base, allowing for easy relocation between work sites, while a lifting mechanism adjusts the discharge height to accommodate trucks, storage bins, and material piles of varying heights.
A complete mobile belt conveyor consists of the following core components:
The frame serves as the structural backbone of the equipment; typically constructed from welded square tubing or channel steel, it comes in either telescopic or fixed-length versions. The tubular steel design ensures sufficient structural strength while keeping the unit lightweight and aesthetically pleasing.
The conveyor belt is the component that directly carries and conveys the material; depending on material characteristics, options include standard flat belts, anti-slip patterned belts, or belts with sidewalls. Belt width is a key parameter determining conveying capacity.
The drive system provides the power; it typically utilizes a motor paired with a gearbox or a motorized pulley, and can be configured for either tail-end or head-end drive. The motorized pulley integrates the motor and drum into a single, compact unit, making it the mainstream drive solution for mobile conveyors.
Idler sets support the conveyor belt and the material; upper idlers bear the load, while lower idlers support the empty return belt. On longer models, self-aligning idlers are installed in the middle sections to prevent belt mistracking.
The mobile travel mechanism is the key feature distinguishing mobile belt conveyors from stationary equipment; the base is equipped with both swivel and fixed casters (featuring brakes), allowing for manual movement. Heavy-duty models are fitted with a towing hitch, enabling relocation via forklift or tractor.
The tensioning and tracking adjustment mechanism uses a tail-end screw rod to tension the belt and adjustment screws on both sides to correct mistracking and slippage during operation.
Additionally, the equipment can be fitted with optional accessories such as hoppers, belt scrapers, guardrails, rain covers, variable frequency drives (VFDs), integrated belt scales, and discharge chutes.
When Huaqiang Heavy Industry assists clients from fertilizer plants, we typically verify the following parameters before customizing a model; you can use this list as a reference when making a purchase:
Materials to be conveyed: wet manure, powdered fertilizer, granular fertilizer, or bagged goods;
Required conveying capacity (tonnage per hour);
Conveying distance, loading height, and incline angle;
Site environment: indoor facility, open-air site with dust, or outdoor location without a power supply;
Requirements for hydraulic lifting, telescopic functionality, or dust covers.
