What are the advantages of different types of Fabric Conveyor Belts?

In the field of industrial conveying, Fabric Conveyor Belts are widely used in various industries such as mining, ports, power, and chemical industries for medium and light-load transportation scenarios. However, different types of Fabric Conveyor Belts have significant differences in material engineering, mechanical properties, and applicable working conditions. This article will systematically explain the characteristics and advantages of different types of Fabric Conveyor Belts to help you make a better choice.

The EP Conveyor Belt uses polyester fibers as the warp yarn and nylon fibers as the weft yarn, suitable for medium to long-distance, large-capacity, and high-speed material transportation.

1. Core advantages of EP Conveyor Belt

• Low elongation rate: The elongation rate under rated tension is much lower than that of the NN Conveyor Belt, suitable for long-distance transportation, reducing the frequency of tension device adjustment.
• High modulus: Tension fluctuations during startup and operation are small, and the operation is stable.
• Moisture resistance and heat resistance: Not sensitive to moisture, stable performance in humid environments, and less prone to hydrolysis.
• High cost performance: Stable comprehensive performance and relatively moderate price.

2. Application scenarios

• Ground coal transportation system in the coal mining industry
• Bulk cargo transportation at ports
• Transportation of limestone and clinker from cement and lime factories
• Suitable for more scenarios requiring long-distance and large-capacity transportation lines

3. Selection suggestions

The EP Conveyor Belt is more suitable for scenarios with elongation requirements, longer running distances, and higher humidity environments. The strength range is usually 200-2500 N/mm, and customers can choose the corresponding strength grade based on actual tension requirements.

The NN Conveyor Belt uses nylon fibers as the longitudinal and transverse skeleton materials. Nylon fibers have excellent flexibility and fatigue resistance, being the most flexible type among all Fabric Conveyor Belts.

1. Core advantages of NN Conveyor Belt

• High strength: Under the same number of layers, the strength of the NN Conveyor Belt is higher than that of EP, reducing the number of skeleton layers and the weight of the belt.
• Fatigue resistance: High retention rate after repeated bending, suitable for working conditions with small drum diameters and frequent bending.
• Good flexibility: The base belt body is soft, making installation and joint processing easier, and having strong adaptability.
• Impact resistance: Lower modulus, effectively absorbing impact energy to protect the belt from damage.

2. Application scenarios

• Coal mining face drift transportation
• Underground extendable conveyor belt machine
• Working conditions with frequent bending or start-stop

3. Selection suggestions

It is suitable for working conditions with small drum diameters, frequent bending, and high impact loads. Also, note that in long-term immersion in water conditions, a water-resistant formula should be selected.

The CC Conveyor Belt uses cotton canvas as the skeleton material. Cotton fibers have good bonding performance, but the strength is lower and the elongation rate is large.

1. Core advantages of CC Conveyor Belt

• Low cost: The price of raw materials is low, making it the most cost-effective choice among all fabric core conveyor belts.
• Good bonding performance: The natural affinity of cotton fibers to rubber, high adhesion between the covering rubber and the skeleton layer.
• Suitable for light-load scenarios: Suitable for short-distance transportation scenarios with low strength requirements, economical and practical.
• Easy installation: Light weight, good flexibility, facilitating on-site joint and installation.

2. Typical applications

• Suitable for grain processing plants
• Light-load, short-distance, low-tension scenarios
• Can be used as temporary conveying facilities

3. Selection suggestions

The strength range of the CC Conveyor Belt is usually 200-800 N/mm, suitable for short-distance transportation scenarios with low tension and cost sensitivity.

Kevlar conveyor belts are made of Kevlar fibers as the main material, featuring extremely high strength, low elongation rate, high temperature resistance, and lightweight. They are high-end products among conveyor belts.

1. Core advantages of Kevlar conveyor belts

• Ultra-high strength: The strength grade of Kevlar can reach 1000-5000 N/mm
• Elongation rate: Under rated tension, the elongation rate is 0.1% - 0.3%, much lower than EP and NN belts, suitable for long-distance transportation
• Lightweight: The density is low, significantly reducing the driving power and structural load
• High temperature resistance: Excellent thermal stability performance, can be used for a long time at 150°C - 200°C
• Corrosion resistance: Kevlar has natural resistance to corrosive environments such as acids, alkalis, and salt fog, no special protection required

2. Typical applications of Kevlar conveyor belts

• Suitable for long-distance transportation
• High tension, large drop-off conditions
• Suitable for transporting high-temperature materials
• Offshore platforms, corrosive environments

3. Selection suggestions for Kevlar conveyor belts

Although the initial investment is relatively high, the combined advantages of lightweight, low energy consumption, and long lifespan can recover the cost within 2-3 years. It is suitable for conditions with high energy efficiency requirements, long transportation distances, or where traditional steel wire rope core conveyor belts are limited due to excessive weight.

Kevlar conveyor belts occupy an important position in the industrial transportation field due to their diverse structures and wide adaptability. Different types of Kevlar conveyor belts have different advantages.
