Selecting the appropriate conveyor belt type for transporting iron ore depends on several factors, including the ore’s properties (abrasiveness, moisture content, lump size), environmental conditions, and operational requirements (speed, capacity, distance). Here are the most suitable conveyor belt types for iron ore applications:
1. Steel Cord Conveyor Belts (ST Belts)
– Best for: Long-distance, high-capacity transport.
– Why? High tensile strength (up to 10,000 kN/m) to handle heavy loads and long spans.
– Features:
– Steel cables embedded in the belt for reinforcement.
– Resistant to impact and elongation.
– Used in large-scale mining operations.
2. Multi-Ply Fabric Belts (EP or NN Belts)
– Best for: Medium-duty applications with moderate distances.
– Why? Good flexibility and resistance to abrasion.
– Features:
– EP (Polyester-Nylon) belts offer high strength and low elongation.
– NN (Nylon-Nylon) belts provide better impact resistance.
3. Heat-Resistant Conveyor Belts
– Best for: Iron ore transported at high temperatures (e.g., from sintering or pelletizing plants).
– Why? Prevents degradation due to heat exposure.
– Features: Made with special rubber compounds (e.g., SBR or EPDM).

4. Chevron/Profiled Belts
– Best for: Inclined transport of iron ore (to prevent rollback).
– Why? Cleats or ribs improve grip on steep slopes (up to 30°–40°).
– Features: V-shaped patterns reduce material spillage.

5. Fire-Resistant & Anti-Static Belts
– Best for: Underground mining or areas with explosion risks.
– Why? Prevents static buildup and resists ignition.
6. Heavy-Duty Impact-Resistant Belts
– Best for: Handling large iron ore lumps (e.g., from crushers).
– Why? Extra cushioning layers absorb impact forces.
Key Considerations When Choosing:
– Abrasion Resistance: Iron ore is highly abrasive; choose belts with high-wear rubber covers.
– Moisture & Chemical Resistance: Wet or chemically treated ores may
