Aramid Conveyor Belt

Aramid Conveyor Belt uses a high-strength, low-elongation aramid carcass to combine high tensile capacity with reduced belt weight. It is designed for demanding conveyor systems where conventional textile belts may not provide sufficient strength, while a steel cord construction may add unnecessary mass.

With its high strength-to-weight ratio, low stretch and non-metallic reinforcement, the belt is especially suitable for long-distance, high-tension and heavy-duty conveying in mining, quarrying, cement, ports, power plants and other bulk material handling applications.

Why Choose Aramid Conveyor Belt

◆ Lightweight & Energy Efficient: Aramid combines high tensile performance with very low material density, allowing the belt to achieve demanding load-carrying capability without the heavy reinforcement associated with steel-cord constructions. The reduced moving weight can help lower conveyor power demand, especially on long-distance systems. Low-rolling-resistance rubber compounds can also be selected to further improve conveyor energy efficiency.
◆ High Impact & Tear Resistance: The high strength and toughness of aramid help the belt withstand impact, cutting and tearing from large, sharp or heavy conveyed materials. Its reinforced carcass distributes impact loads more effectively and helps limit damage propagation, making the belt well suited to demanding loading zones, mining operations and other heavy-duty bulk handling applications.
◆ Excellent Heat Stability & Flame-Resistant Options: Aramid fibers maintain good mechanical stability at elevated temperatures and do not melt like conventional polyester or nylon fibers. This gives the reinforcement an important advantage in demanding thermal environments. For hot-material or fire-risk applications, the belt can be combined with heat-resistant or flame-resistant rubber compounds according to the required operating conditions.
◆ Corrosion-Resistant Reinforcement: As a non-metallic reinforcement material, aramid does not rust when exposed to moisture and provides good resistance to many chemical and environmental media. This makes aramid conveyor belts particularly attractive for humid, corrosive or chemically demanding environments where deterioration of metallic reinforcement may be a concern.
◆ Low Elongation & Long-Term Reliability: The high modulus of aramid helps limit belt stretch under working tension, providing good dimensional stability and reduced take-up demand during operation. Its fatigue-resistant reinforcement, together with durable top and bottom rubber covers, helps protect the belt against repeated flexing, abrasion and impact for reliable performance in long-distance and heavy-duty conveying systems.

Aramid Conveyor Belt Construction

An aramid conveyor belt is built around a high-strength aramid carcass, where longitudinal aramid yarns run continuously in the belt direction to carry the primary working tension. Transverse reinforcement ties the structure together across the belt width, helping stabilize the carcass, distribute impact loads, and resist tearing and lateral deformation under demanding conveying conditions.

What makes this structure different is the combination of high modulus, high tensile strength, and low material density. The aramid reinforcement stretches very little under working load while adding significantly less carcass weight than steel reinforcement. The result is a strong, lightweight, and dimensionally stable conveyor belt that can require less take-up travel than conventional multi-ply textile constructions and provide high tensile capacity with a lighter reinforcement system than comparable steel-reinforced designs. With no steel in the carcass, the reinforcement is also inherently resistant to rust.

Rubber Cover Grade Options

The rubber cover of an Aramid Conveyor Belt can be selected according to the conveyed material, abrasion level, impact conditions and operating environment. For general-purpose applications, H, D and L cover grades provide different balances of tensile strength, elongation and abrasion resistance.

Cover Grade	Min. Tensile Strength	Min. Elongation at Break	Max. Abrasion Loss	Typical Application
H	24 MPa	450%	120 mm³	Cut, gouge and heavy-impact service
D	18 MPa	400%	100 mm³	Severe abrasive service
L	15 MPa	350%	200 mm³	General and moderate-abrasion service

H Grade — Cut & Gouge Resistant: H grade is designed for demanding applications involving large, sharp or coarse materials where cutting, gouging and impact damage are major concerns. It is suitable for materials such as hard rock, ore, limestone, clinker and broken stone.
D Grade — High Abrasion Resistant: D grade is recommended where abrasive wear is the primary concern. Its low abrasion-loss requirement makes it suitable for continuous handling of highly abrasive bulk materials where cover wear must be minimized.
L Grade — General & Moderate Abrasion: L grade is suitable for general conveying and moderately abrasive materials where severe cutting or extreme abrasion resistance is not required. Typical applications include coal, sand, cement, lime and similar bulk materials.

Aramid Conveyor Belt Applicantion


Mining & Quarrying	Cement & Aggregates
Aramid conveyor belts are well suited to high-tension and impact-intensive conveying of ore, rock and other heavy bulk materials. Their high strength-to-weight ratio, low elongation and reinforced carcass help maintain stable operation in long-haul mine and quarry conveyor systems.	For conveying limestone, clinker, crushed stone and other abrasive materials, aramid belts combine high tensile capability with good impact and tear resistance. Suitable cover compounds can be selected to protect the carcass against continuous abrasion, cutting and heavy loading.

Ports & Bulk Terminals	Long-Distance Overland Conveying
Port and terminal conveyors often require high throughput over long center distances. The relatively low weight and low elongation of aramid reinforcement can help reduce take-up demand and moving belt mass while supporting reliable ship loading, unloading and stockyard transfer operations.	Aramid conveyor belts are particularly suitable for long-distance and high-tension overland conveyor systems where belt weight and elongation are important design factors. Their lightweight high-strength carcass helps maintain dimensional stability and can reduce belt-related moving resistance compared with heavier reinforcement systems.

Frequently Asked Questions

Q How much does an aramid conveyor belt elongate under load?

Aramid has a high modulus and low elongation, allowing the belt to maintain good dimensional stability under working tension. For the listed DPP specifications, elongation at 10% of rated tensile strength is specified at a maximum of 0.5%. This helps reduce take-up travel compared with conventional multi-ply textile belts. Actual operating elongation also depends on belt rating, working tension, splice design and conveyor conditions.

Q Why is an aramid conveyor belt lighter than a steel cord belt?

Aramid has a much lower material density than steel while providing a high strength-to-weight ratio. This allows an aramid conveyor belt to achieve high tensile capacity with a relatively lightweight reinforcement system. Lower moving belt mass can be particularly beneficial on long-distance and high-tension conveyors, where belt weight contributes to overall conveyor resistance and power demand.

Q Do thicker rubber covers eliminate the weight advantage of an aramid belt?

Not necessarily. Increasing the top or bottom cover thickness adds rubber weight to any conveyor belt, but the main weight advantage of an aramid belt comes from its lightweight high-strength carcass. Even when thicker covers are selected for severe abrasion or impact conditions, the aramid reinforcement can still retain a weight advantage over comparable steel-reinforced constructions.

Q Can the top and bottom covers use different rubber compounds?

Yes. The carrying side and pulley side can be designed for different operating requirements. For example, the top cover may use an abrasion-resistant, heat-resistant or cut-resistant compound, while the bottom cover may use a low-rolling-resistance compound for long-distance conveying. The final compound combination must consider vulcanization compatibility, adhesion performance and actual operating conditions.

Q How is the aramid carcass protected against delamination?

Reliable bonding between the rubber covers and the aramid carcass is achieved through appropriate carcass treatment, adhesion rubber and controlled vulcanization. Proper bonding helps transfer working loads through the belt structure and reduces the risk of cover separation or internal delamination during repeated flexing. Adhesion performance can be verified using standardized conveyor belt adhesion testing methods such as ISO 252.

Q Can an aramid conveyor belt be supplied with additional rip protection?

Yes. For applications with a high risk of longitudinal tearing or penetration, an additional breaker or rip-stop reinforcement layer can be incorporated into the belt construction. This layer helps restrict tear propagation after penetration by sharp or oversized material. The required reinforcement depends on factors such as material shape, lump size, loading height and expected impact severity.

Q How is an aramid conveyor belt spliced?

High-strength aramid conveyor belts are typically joined using an engineered finger vulcanized splice. The carcass ends are prepared into interlocking finger patterns and joined through controlled hot vulcanization. Finger length, splice geometry, rubber materials and vulcanizing conditions are selected according to the belt strength and carcass design to provide effective tensile-load transfer through the splice.

Q Is an aramid carcass affected by moisture or corrosion?

Aramid is a non-metallic reinforcement, so it does not rust like steel cords when exposed to moisture. This makes aramid attractive for humid or corrosion-sensitive conveyor environments. However, the complete belt still requires suitable rubber covers, edge protection and properly constructed splices because moisture and environmental exposure can affect the rubber and bonding system if the belt is damaged.

Q Is an aramid conveyor belt resistant to chemicals?

Para-aramid provides good resistance to many environmental and chemical media, but the chemical resistance of the finished conveyor belt cannot be determined by the carcass material alone. The rubber cover is normally the component directly exposed to oils, acids, alkalis or other chemicals, so the appropriate cover compound should be selected according to the conveyed material, concentration, temperature and exposure conditions.

Q Why choose aramid instead of an EP/NN or steel cord conveyor belt?

Aramid is particularly suitable when a conveyor requires a combination of high tensile capacity, low belt weight and very low elongation. Compared with conventional EP/NN textile belts, it can provide higher tensile capability with lower take-up demand. Compared with steel cord belts, it offers a lighter, non-metallic reinforcement system. Steel cord remains the preferred option where the highest possible tensile capacity is required.

Q Is an aramid conveyor belt suitable for high-impact loading?

Yes, when the belt construction is properly selected for the application. High-strength longitudinal aramid reinforcement carries the main working tension, while transverse reinforcement helps distribute impact loads and resist tearing. For severe loading zones, the belt can also be combined with thicker impact-resistant covers or additional breaker reinforcement according to drop height, lump size and material characteristics.

Q Is an aramid conveyor belt suitable for heat-resistant or flame-resistant applications?

Yes, but the aramid fiber alone does not determine the temperature or flame rating of the finished belt. Para-aramid provides excellent thermal stability, while actual conveyor belt performance depends on the cover rubber, adhesion system and complete belt construction. Heat-resistant or flame-resistant compounds should therefore be selected according to the required operating temperature, conveyed material and applicable fire-safety requirements.
