Steel Cord Conveyor Belt Working Conditions Selection Guide
Based on our engineering experience in steel cord conveyor belt applications, selection is generally influenced by operating tension, material properties, temperature conditions and conveying distance.
Consider your operating environment
If your environment is between -10°C and -50°C, you should consider cold resistant rubber compounds. If your material temperature is above ~80°C, heat resistant belt types are generally recommended.
Check your conveying system length
If your conveying distance is below ~1 km, short-distance EP systems are often sufficient. If your system exceeds ~3 km, steel cord conveyor belts are generally more suitable for long-distance stability.
Understand your conveyor load & strength requirement
If your system tension is below 800 kN/m (800 N/mm), a fabric conveyor belt is generally sufficient. If the tension is above 800 kN/m, we usually recommend using a steel cord conveyor belt for better stability.
Evaluate your material’s abrasion & impact level
If you are handling ore, clinker or highly abrasive materials, wear-resistant covers are usually required. If your system has strong impact loads, anti-tear reinforcement structures are recommended.

Steel Cord Conveyor Belt Structure Breakdown
The steel cord conveyor belt is composed of multiple engineered layers that work together to ensure high tensile strength, impact resistance and stable long-distance conveying performance under heavy-duty operating conditions.
Top Rubber Cover
The top cover is the outer protective rubber layer designed to resist abrasion, impact and cutting forces from conveyed materials during operation.
Bonding Rubber Layer
The bonding rubber layer surrounds and secures the steel cords in place to ensure structural stability, prevent internal slippage and improve fatigue resistance under dynamic load conditions.
Steel Cord Layer
The steel cord layer is the core tensile structure of the belt, composed of high-strength steel cords that provide load-bearing capacity, low elongation and stability for long-distance conveying systems.
Bottom Cover
The bottom cover is the lower protective rubber layer that reduces friction with rollers, resists mechanical wear and ensures stable running performance of the conveyor belt system.
Rubber Compound Selection for Steel Cord Conveyor Belt Covers
We select coating formulations based on your material type, abrasion resistance rating, temperature conditions, safety requirements, and industrial operating environment.
| Rubber Compound | Primary Application Scenario | Engineering Selection Logic |
|---|---|---|
| NR / SBR Blend | General conveying in mining, ports, cement and steel plants | Used as a standard base compound for balanced performance in general bulk material handling systems. |
| SBR (High Abrasion Grade) | Mining (ore, coal), port bulk handling, cement clinker transport | Selected when abrasion resistance is the primary requirement under continuous material wear conditions. |
| EPDM (Heat Resistant) | Cement industry, steel plants, high-temperature conveying systems | Applied when operating temperatures are consistently high, especially in clinker and hot material handling. |
| BR Blend (Impact Resistant) | Mining loading zones, port unloading systems, steel scrap handling | Used where strong impact and drop forces require improved elasticity and wear resistance balance. |
| CR (Flame & Weather Resistant) | Mining safety systems, outdoor conveyors, harsh weather environments | Selected for applications requiring flame resistance and environmental durability under exposed conditions. |
| NBR (Oil Resistant) | Port machinery zones, steel plants, recycling and oil-exposed materials | Applied where oil, grease or hydrocarbon exposure may affect belt surface performance. |
