The conveying capacity of a Belt Conveyor Machine can vary widely depending on several factors, including the type of conveyor, belt width, belt speed, material characteristics, and the design of the conveyor system. Here is a detailed analysis:
Belt Width
Generally, the wider the belt, the greater the conveying capacity. Common belt widths range from 500mm to 2400mm. For example, a 500mm wide belt might have a relatively small capacity, suitable for transporting 100-300 tons per hour (t/h) of general materials. In contrast, a 2400mm wide belt can handle 2000-5000 t/h or even more in some large-scale mining or port applications.
Belt Speed
Belt speed is another crucial factor. Higher speeds lead to greater conveying capacity. Typically, belt speeds range from 1 meter per second (m/s) to 6 m/s. In a cement plant, a conveyor with a speed of 1-2 m/s might be used to transport 500-1000 t/h of cement raw materials. In high-speed applications like some modern coal mines, belts running at 4-6 m/s can achieve a conveying capacity of 3000-8000 t/h.
Material Characteristics
The density, particle size, and flowability of the material being conveyed have a significant impact on the conveying capacity. Dense and fine-grained materials like iron ore can be transported in larger quantities per unit volume compared to lightweight and bulky materials like sawdust. For example, a conveyor handling iron ore with a density of 4-5 tons per cubic meter can have a much higher capacity than one handling grain with a density of about 0.7-0.8 tons per cubic meter.
Conveyor System Design
The layout and design of the conveyor system, including the number of idlers, the angle of inclination, and the presence of curves or bends, also affect the conveying capacity. A conveyor with a gentle inclination angle can usually carry more material than one with a steep angle. Additionally, a well-designed system with properly spaced idlers can support the belt better and allow for a higher material load.
Mining Industry
In large open-pit mines, belt conveyors are often used to transport huge amounts of ore and waste rock. Some high-capacity conveyors can have a conveying capacity of 5000-10000 t/h or even higher. For example, in some copper mines, conveyors with a width of 1800mm and a speed of 5 m/s can handle 8000-10000 t/h of copper ore.
Port Industry
At ports, belt conveyors are used to load and unload bulk materials such as coal, grain, and iron ore. The conveying capacity of these conveyors can range from 1000 t/h to 6000 t/h. A port conveyor for unloading coal might have a capacity of 3000-4000 t/h, depending on the size of the ships and the throughput requirements.
Power Industry
In coal-fired power plants, belt conveyors are used to transport coal from the coal yard to the boiler. The capacity of these conveyors is usually in the range of 500-2000 t/h. A medium-sized power plant might have a conveyor with a capacity of 1000-1500 t/h to ensure a continuous supply of coal for power generation.
Chemical Industry
In the chemical industry, belt conveyors are used to transport various raw materials and products. The conveying capacity can vary widely depending on the specific process and material. For example, in a fertilizer plant, conveyors might have a capacity of 200-800 t/h for transporting granular fertilizers.
