Industrial conveyor belts

Industrial conveyor belts are devices used to efficiently move materials during production, manufacturing and logistics processes. They are widely used in a variety of industries such as mining, manufacturing, food processing, packaging, and airport baggage handling. Conveyor belt systems can be designed in many different configurations to suit specific tasks and environmental requirements.

 

Industrial conveyor belt systems primarily consist of core components such as a motor, drive rollers, idler rollers, load-bearing idlers, return idlers, tensioning devices, a circular conveyor belt, and a metal structural frame, all working in tandem. The system receives power from the motor, which is transmitted to the drive rollers via a reducer, using friction to drive the conveyor belt continuously. Key parameters such as operating speed and conveying capacity depend on the drive power; belt speed is typically 0.8-4.0 m/s, and belt width is 500-2400 mm. The conveyor belts are mostly made of materials such as rubber, PVC, and PU, possessing properties such as wear resistance, tear resistance, and, under specific operating conditions, high temperature resistance and antistatic properties.

What are the different types of industrial conveyor belts?

For conveying small batches of materials, light-duty conveyor belts can be selected, while for conveying large, abrasive materials, wear-resistant heavy-duty conveyor belts can be selected.

Lightweight conveyor belts are made of polymer materials, allowing working tension of less than 50 N/mm. They are thinner, dimensionally stable, have good tension performance, bright colors, and are safe and non-toxic, making them suitable for use in food processing, logistics, tobacco production, and other industries. Their thickness ranges from 0.5 to 8 mm, and common widths range from 100 to 2000 mm. Both ends of the conveyor belt can be fitted with hook-type or nail-type fasteners, allowing for easy connection via pins, making installation and use convenient.

Heavy-duty conveyor belts use EP impregnated canvas as the skeleton material, combined with rubber, resulting in high strength, a thin and lightweight body, soft texture, good troughing properties, and ample elasticity. They are also impact-resistant, wear-resistant, and corrosion-resistant, making them suitable for conveying heavy materials in industries such as metallurgy, building materials, and mining. Thickness ranges from 8 to 30 mm, with common widths from 500 to 3000 mm. Matching fasteners are available in two types: pin-plate and plate. Pin-plate fasteners are suitable for small rollers, while plate fasteners are suitable for large rollers and can also be used in scenarios where leak-proof splicing is not required.

What is the working principle of industrial conveyor belts?

The conveyor belt is wound around the transmission roller and the tail roller to form an endless endless belt. The conveyor belt is supported by the support roller to limit the deflection sag, and the tensioning device provides the required tension for the normal operation of the conveyor belt. When working, the motor drives the transmission roller through the reducer, and the friction between the transmission roller and the conveyor belt makes the conveyor belt move continuously. The conveyed items are transported to the unloading location by the friction between it and the conveyor belt.

What are the structural components of industrial conveyor belts?

Generally consists of a covering layer, a skeleton layer and a bottom layer. The covering layer usually has the characteristics of wear resistance, oil resistance, acid and alkali resistance, etc., which is used to protect the skeleton layer and carry materials; the skeleton layer is the main supporting structure of the conveyor belt, providing strength and flexibility, and common materials include canvas, nylon, polyester, wire rope, etc.; the bottom layer is in contact with the driving roller and the roller, and is required to have good wear resistance and tear resistance.

What are the applications of conveyor belts in the industrial field?

In automobile manufacturing workshops, industrial conveyor belts form the basic veins of automated production lines. Heavy parts such as engines and gearboxes are transported before assembly through heavy rubber conveyor belts and accurately positioned to assembly stations; lightweight materials such as interior parts and electronic components are sorted and transported by light PU conveyor belts to ensure a coherent and efficient production rhythm. In the electronics industry, precision chips, circuit boards and other products have extremely high requirements for cleanliness. Light anti-static PVC conveyor belts rely on their static-free and pollution-free characteristics to achieve material flow in dust-free workshops.

In the field of logistics and warehousing, conveyor belts are the key to achieving efficient sorting. In the express distribution center, modular chain conveyor belts and intelligent sorting systems can handle tens of thousands of packages per hour and automatically sort them to different exits according to the destination. In mining scenarios, long-distance, high-capacity steel rope core conveyor belts can continuously transport tons of ore from underground mining faces to surface processing areas. The maximum conveying distance can reach several kilometers, and the daily transportation volume can reach thousands of tons.

Industrial conveyor belts price

Standard PVC or lightweight PU conveyor belts typically cost between $10 and $50 per meter. However, rubber or silicone belts requiring high temperature resistance, abrasion resistance, chemical corrosion resistance, or food-grade standards can jump to $50 to $300 per meter. Sidewall conveyor belts, with the addition of sidewalls and partitions, are generally $100 to $400 per meter; the more complex the structure, the higher the price. Steel cord conveyor belts, used for heavy-duty long-distance transport in mines and ports, are the most expensive, reaching over $300 per meter. The price depends on the number of canvas layers, cover rubber thickness, tensile strength, steel cord diameter, and rubber grade.

What is the general carrying capacity of belt conveyors?

The conveying capacity of belt conveyors varies depending on their design, application, and working environment, ranging from light to heavy loads. Light-load conveyors are mostly used in light industries such as food and electronics, typically conveying materials weighing between 10 and 200 kg. Medium-load conveyors are suitable for industrial assembly lines and similar scenarios, transporting materials weighing between 200 and 500 kg. Heavy-load conveyors are used in mines, ports, and other locations handling bulk materials, with a single unit capable of carrying a weight of over 1 ton. Some specially designed heavy-load models can even withstand weights of tens of tons, adapting to various complex industrial applications.

The following are the theoretical load capacity ranges under some common specifications (horizontal conveying, uniform loading):

Bandwidth (mm)	Conveying speed (m/s)	Conveying capacity (t/h, estimated based on a bulk density of 1.0t/m³)
500	1.0	100～150
650	1.25	150～300
800	1.6	300～500
1000	2.0	500～800
1200	2.5	800～1200
1400	3.15	1000～1800
