Heavy Duty Rubber Conveyor Belt – Engineered for Mining, Quarry & Heavy Industry

Product Definition: A heavy duty rubber conveyor belt is a high-tensile, abrasion-resistant belting system engineered for bulk haulage of sharp, heavy materials such as ore, crushed rock, coal, and slag under high-impact conditions. Typical systems handle throughputs ranging from 500 to over 30,000 tons per hour depending on belt width and operating speed. This belt combines a robust fabric or steel cord carcass with a wear-resistant rubber cover to deliver exceptional tear strength and impact absorption.

STANDARDS All belts are manufactured in compliance with international standards including DIN 22102, AS 1332, RMA IP-22, and SABS 1173.

Key Performance Features

Extreme Impact Absorption Thick rubber cover cushions falling boulders.

Superior Gouge Resistance Grade H/D/L covers maintain thickness with jagged aggregates.

High Tension Stability Resists elongation under heavy start-up loads.

Harsh Environment Adaptability Heat/oil/cold-resistant variants available.

Technical Specifications

Selecting the correct belt requires matching tonnage, distance, and safety factors (8–10:1) to international standards.

Application-Specific Solutions

Mining & Processing

Steel cord carcasses handle heavy ore surges over long distances.

Cement & Lime

Heat-resistant covers up to 200°C prevent premature hardening.

Aggregate & Quarry

EP types with H-grade covers resist sharp limestone and granite.

How to Choose？

Material Traits – Size, abrasiveness, impact drop height.

Throughput – Tons per hour determines width and speed.

Conveyor Path – Length, lift, curves affect tensile needs.

Site Conditions – UV, moisture, chemicals finalize compound.

Splicing & Maintenance

Three splicing methods: mechanical fasteners, hot vulcanization, cold bonding. Routine checks: weekly splice monitoring, monthly cover inspection, quarterly tracking alignment.

Quality Assurance

ISO 9001:2015 Certified facility. Factory-direct supply with warranty and rapid on-site support.

FAQ

EP vs Steel Cord – which is better?

EP is flexible and cost-effective for medium distances. Steel cord is required for very long hauls and extreme impact.

Which cover grade to specify?

Grade H for severe cutting, Grade D for highly abrasive materials, Grade L for general heavy-duty use.

Expected service life?

Typically 3–5 years in standard quarry operations with proper maintenance.
