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.

 

What Makes a Quality Industrial Conveyor Belt?

The carcass provides tensile strength and dimensional stability, the cover compound protects against wear and environmental factors, and the splice ensures joint integrity—together, they determine the belt's overall durability and performance.

The Carcass (Skeleton Layer)

This is the structural core that provides tensile strength and dimensional stability. Options include EP (polyester-nylon) fabric for general applications, NN (nylon-nylon) fabric for high-impact environments, and steel cord for ultra-high tension long-distance conveying.

The Cover Compound

The top and bottom rubber or polymer layers that protect the carcass and directly contact the conveyed material. Cover compounds are formulated for specific conditions—abrasion-resistant for sharp ores, heat-resistant for hot clinker, oil-resistant for chemical applications, and FDA-grade for food contact.

The Splice (Joint)

The connection point where the belt ends are joined. Mechanical splices offer quick installation for light to medium applications; vulcanized splices provide a seamless, durable joint for heavy-duty, high-tension operations.

What are the different types of industrial conveyor belts?

Light-Duty Conveyor Belts – Engineered for Precision and Hygiene

Light-duty belts are defined by working tensions below 160 PIW (pounds per inch of width). They are designed for controlled environments handling uniform, lightweight materials where hygiene, precision, and cleanability are paramount.

Sub-Type	Material	Thickness	Key Applications	Critical Features
PVC Belt	PVC	1.0 – 8.0mm	Food packaging, electronics assembly, logistics sorting	Lightweight, cost-effective, easy to clean
PU Belt	Polyurethane	0.5 – 5.0mm	Food processing, pharmaceuticals, cleanrooms	FDA-compliant, highly wear-resistant, flexible
Modular Plastic Belt	Plastic modules	Custom assembled	Seafood processing, cold storage, wash-down environments	Removable sections, water-resistant, low maintenance
Teflon/PTFE Belt	PTFE-coated fiberglass	0.25 – 1.0mm	Heat sealing, baking lines, drying ovens	Heat-resistant up to 260°C, non-stick surface

Light-duty belts are ideal for industries where product quality and sanitation standards are critical. All food-contact materials are available with FDA and EU-compliant certifications.

Heavy-Duty Conveyor Belts – Built to Withstand Extreme Conditions

Heavy-duty belts operate at working tensions above 160 PIW and are engineered for coarse, abrasive bulk materials, high impact energy at loading points, and continuous operation in harsh environments such as mines, quarries, cement plants, and ports.

Sub-Type	Carcass Material	Thickness	Key Applications	Critical Features
EP Fabric Belt	Polyester fabric	6 – 20mm	Coal mines, building materials, cement plants	High tensile strength, impact-resistant, wear-resistant
NN Fabric Belt	Nylon fabric	8 – 16mm	Fertilizer plants, ore handling, docks	Excellent flexibility, heat and humidity resistance
Steel Cord Belt	Steel wire rope core	10 – 30mm	Long-distance mining conveyors, ports	Ultra-high strength, minimal stretch, long service life
Heat-Resistant Belt	EP fabric + heat-resistant rubber	8 – 14mm	Cement kilns, coking lines, sinter plants	Withstands up to 250°C, crack-resistant
Chevron/Pattern Belt	EP fabric + patterned rubber cover	6 – 12mm	Inclined bulk material handling, grain transport	Non-slip surface, suitable for angles up to 30°

Heavy-duty belts from Dahan are engineered with reinforced edges and impact-resistant covers to deliver extended service life in the most punishing environments.

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.

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

Frequently Asked Questions

How long do industrial conveyor belts typically last?

Service life depends on material abrasiveness, impact frequency, and operating environment—typically 3-5 years in mining, 10+ years in indoor light-duty applications.

What's more important—belt thickness or rubber quality?

Rubber quality matters more than thickness. A high-quality compound outlasts a thicker belt made with low-grade materials.

How do I prevent belt mistracking?

Check for misaligned idlers, off-center loading, or improper splicing. Adjust idlers against the mistracking direction; if persistent, conduct a site survey.

Should I choose mechanical or vulcanized splices?

Mechanical splices suit light to medium-duty applications; vulcanized splices are essential for heavy-duty, high-tension, or abrasive environments.

What does "EP" and "NN" mean in belt specifications?

EP (Polyester-Nylon) offers good strength with low stretch for general use; NN (Nylon-Nylon) provides higher tensile strength and flexibility for high-impact applications.
