Coal conveyor belt

Coal conveyor belt is a conveying equipment system specially used for transporting coal, raw coal, coke and other combustible solid minerals. It uses the belt as a carrier to transport coal from one location to another, and can meet the needs of long-distance, large-volume and high-efficiency transportation.

Coal conveyor belt width：Up to 2.4m

Coal conveyor belt length：Up to 10,000m

Handling Capacity：Up to 10,000 m³/h

Belt Speed： Up to 6.0m/s

Belt Options：Antistatic, Hard wearing, Fire/Oil /Corrosion resistant

Application: coal mines, thermal power plants, coal washing plants, steel mills, etc.

What is the coal conveyor belt?

Coal conveyor belt is a belt conveying equipment used in coal mining and transportation to transport coal in a continuous manner. It is usually composed of a belt core and a covering layer. The belt core provides strength and flexibility, while the covering layer protects the belt core and prevents coal from wear and corrosion. Coal conveyor belt is driven by a drive device to circulate. In underground coal mines, coal preparation plants, coal terminals and other places, it transports coal from mining faces, storage points, etc. to designated locations, realizing efficient and continuous transportation of coal.

What are the different types of coal conveyor belts?

Category	Type	Image	Features	Typical use cases
By structure	Fixed belt coal conveyor		Permanent installation, suitable for long-term operation	Power plants, coal processing plants
	Mobile coal conveyor		Movable, flexible layout	Temporary yards, loading and unloading areas
	Telescopic coal conveyor		Can be extended or retracted to reach different distances	Truck/ship loading
	Inclined coal conveyor		Designed for vertical or inclined coal transportation	Underground mines, hills Mausoleum area
By belt material	Cotton (canvas) coal conveyor belt		Low cost, low strength	Light, short distance
	Nylon (NN) coal conveyor belt		High strength, good flexibility	Medium/long distance, standard transportation
	Polyester (EP) coal conveyor belt		Low elongation, moisture and heat resistance	Wet environment (such as coal washing)

How does the coal conveyor belt work?

Coal conveyor belts transport coal based on continuous cyclic motion. The specific process is as follows:

Starting phase: Coal is placed on the conveyor belt, and the drive roller drives the conveyor belt through friction.

Transportation phase: The conveyor belt, supported by rollers, transports coal from the loading point to the destination, such as from the mine to the ground, or transports coal between different processing equipment.

Unloading phase: At the unloading point, the coal is unloaded from the conveyor belt, completing the transportation process.

What are coal conveyor belt made of?

Coal conveyor belt is mainly composed of the following parts:

Belt body: the main part that carries coal, made of materials such as canvas belt or steel cord belt, responsible for carrying coal.

Drive device: provides power, usually composed of electric motor, reducer and drive roller.

Tensioning device: maintains the appropriate tension of the belt body, ensures that the conveyor belt has a certain initial tension at the separation of the drive roller to prevent slipping.

Supporting device: such as roller group, supports the conveyor belt, reduces running resistance, and keeps the belt body stable.

What are the advantages of coal conveyor belts?

Solve the problem of material return

Fine coal particles adhering to the coal conveyor belt after unloading will fall off along the return journey, resulting in material loss and dust generation. Primary and secondary belt cleaners installed at the unloading point can remove coal remaining on the belt surface.

Deal with coal scattering and blockage

Coal may fall off the edge of the conveyor belt during transportation, causing resource waste and equipment damage. Use coal conveyor belts with skirt conveyor belts or sidewall belts to prevent material leakage, and install sweepers and guide chutes to avoid blockage and accumulation of residual materials.

Solve the problem of impact damage

Large pieces of coal falling on the belt, especially at the loading point, will cause impact damage, resulting in tearing and premature failure. Installing impact-absorbing rollers or brackets in the loading area can help cushion the impact of the coal conveyor belt and protect the belt.

Adapt to complex conveying conditions

Coal conveyor belts with patterned conveyor belts or skirt conveyor belts can achieve large inclination angles (up to 90 degrees). Long-distance (several kilometers) transportation can be achieved through multiple conveyor belt relays or intermediate drives.

Application of coal conveyor belts

Coal conveyor belts are widely used in underground mining, surface transportation, coal preparation plants, coal docks and other places. Underground, it transports the coal mined by the coal mining machine from the working face to the pit bottom yard; above the pit, it transports the coal from the wellhead to the coal preparation plant for processing, or directly transports it to coal storage sites or transportation terminals such as railways and ports, so that the coal can be transported to various places.
