Heat Resistant Conveyor Belt

YUFENG Heat Resistant Conveyor Belt is rigorously tested for heat aging, tensile strength, interlayer adhesion and abrasion performance, meeting DIN 22102, ISO 4195, SGS and BV requirements. Widths of 500–3200 mm, thickness, ply layers and molded edges can be customized. Exported to 40+ countries for clinker, sintered ore, coke and steel slag conveying, it delivers reliable high-temperature performance and long service life.

YUFENG is a professional Heat Resistant Conveyor Belt manufacturer with automated vulcanization workshops and a closed-loop quality control system covering rubber compounding, carcass bonding and finished-belt inspection. Our upgraded heat-resistant formula and bonding technology are validated through thermal cycle and 6-month field tests, delivering reliable performance and longer service life in high-temperature conveying applications.

Verified Professional Material & Craft Data

1. EPDM Heat-Resistant Cover Rubber

We adopt modified EPDM rubber compounded with high-temperature stabilizers and anti-aging agents, providing better heat resistance and aging performance than ordinary SBR rubber. The cover rubber supports continuous stable operation at temperatures up to 175℃, with an instant impact temperature peak of up to 600℃. After a 300-hour constant-temperature aging test at 150℃, the tensile strength retention rate remains at ≥85%. The abrasion volume is ≤200mm³, with improved resistance to powdering and cracking. Its ozone and UV resistance also makes it suitable for outdoor high-temperature conveying applications.

2. Reinforcement Carcass Layer

The carcass uses low-shrink EP polyester canvas as the core reinforcement layer and adopts secondary high-temperature vulcanization bonding technology. The thermal shrinkage rate is ≤1.2%, helping reduce belt deviation caused by long-term heat exposure. Interlayer adhesion reaches ≥2.1N/mm, maintaining structural integrity under heavy loads and thermal impact. The high-strength polyester carcass provides reliable support for high-temperature and heavy-load conveying lines.

3. Optional Upgrade Structure

For different working conditions, the belt structure can be customized with additional reinforcement and functional layers. A steel cord reinforcement layer can be added for extra-heavy-load high-temperature conveying, while an anti-tear textile layer is available for sharp and hot materials. For applications involving oily high-temperature residues, an oil- and heat-resistant composite rubber formula can be selected. Flame-retardant and heat-resistant composite structures are also available for conveying environments with higher fire risks.

6-Month Real Industrial Field Test & Comparison with Ordinary Belts

1. Controlled Field Test Conditions

We cooperated with two local heavy-industry factories to conduct a controlled six-month field test, comparing our Heat Resistant Conveyor Belt with mainstream ordinary heat-resistant belts under the same operating conditions. The test was conducted on a cement clinker conveying line with a continuous material temperature of 140℃, 16 hours of daily operation and a daily conveying capacity of 800 tons.

2. Field Test Results

The ordinary market heat-resistant belt developed surface cracking after 45 days and interlayer separation after 72 days, requiring forced replacement. Its total service life was approximately 2.5 months. In comparison, the YUFENG T3 Heat Resistant Conveyor Belt completed the full six-month test cycle without visible cracking or delamination and maintained stable tension. Based on the recorded project data, the estimated service life reached 9–10 months, while annual belt procurement costs were reduced by 62%.

Real Customer Application Cases & On-Site Usage Scenarios

1. Domestic 3000 t/d Cement Production Line

The customer previously used generic heat-resistant belts that required replacement every 2–3 months, resulting in additional maintenance costs and unplanned production downtime. After switching to our T3 Heat Resistant Conveyor Belt, the conveying equipment operated for 10 months without a belt-related breakdown, saving more than $18,000 in annual spare-parts costs. The customer subsequently signed a three-year supply contract with us.

2. Vietnam Steel Mill Sintered Ore Conveying Project

The project involves instant hot sinter impact of up to 450℃. Imported belts cost approximately three times more and had a service cycle of around six months. We customized a T4 heavy-duty Heat Resistant Conveyor Belt for the customer's inclined heavy-load conveying equipment. After passing the local third-party high-temperature aging test, the belt operated continuously for nine months. The customer subsequently increased the second-batch order quantity by 120%.

Main Applicable Industries & Conveying Materials

1. Metallurgy & Steel

Suitable for sintered ore, hot coke, steel slag and hot metal workpieces.

2. Cement & Building Materials

Applicable to high-temperature clinker, calcined limestone and hot mineral powder conveying.

3. Coking & Chemical Industry

Used for hot chemical fertilizer residues and calcined high-temperature chemical raw materials.

4. Foundry Industry

Suitable for hot casting sand and hot metal scrap handling.

5. Power Plants

Applicable to high-temperature fly ash, boiler slag and desulfurization gypsum conveying.

Practical Operation & Maintenance Guide

1. Heat-Resistance Grade Selection

Confirm the continuous material temperature and instantaneous peak temperature before selection, then choose the appropriate T1–T4 grade according to the actual working conditions. This helps avoid unnecessary specification upgrades or insufficient heat resistance.

2. Installation Requirements

For high-temperature conveying systems, matching heat-resistant roller rubber coatings can help reduce localized heat concentration and improve the overall operating condition of the belt.

3. Daily Maintenance

Regularly remove residual hot materials from the belt surface to reduce prolonged localized heating. Under suitable operating and maintenance conditions, this can help extend belt service life by up to 30%.

FAQ

Q1: How do I choose the right temperature grade (T1-T4) for my application?

The selection mainly depends on two key factors: continuous working temperature of the conveyed material and instant peak impact temperature. Generally: T1 for ≤100℃ light chemical and building materials; T2 for ≤125℃ small cement plants and foundry sand; T3 for ≤150℃ medium cement clinker and coke transport; T4 for ≤175℃ steel slag, sintered ore and heavy smelting with 400–600℃ instant impact. Our technical engineers can recommend the most suitable grade based on your specific material type, working temperature and conveying environment, just send us your working condition details.

Q2: What is the typical service life of YUFENG Heat Resistant Conveyor Belt?

Service life varies according to working temperature, material abrasiveness and daily maintenance level. Based on our actual project statistics: T1-T2 light working conditions: 12–18 months; T3 medium working conditions (cement clinker, coke): 8–12 months; T4 heavy high-temperature conditions (steel slag, sintered ore): 6–9 months. Compared with ordinary market heat-resistant belts, our products generally extend service life by 60–80% due to better EPDM formula and higher interlayer adhesion, significantly reducing annual replacement costs.

Q3: Can you customize special heat-resistant belts, and what is the MOQ / sample policy?

Yes, we provide comprehensive customization services for special high-temperature working conditions: composite functional formulas (oil + heat resistant, flame retardant + heat resistant, acid & alkali + heat resistant), structural customization (steel cord reinforcement, anti-tear layer, moulded sealed edge), and size customization (width 500–3200mm, 3–8 ply layers, custom cover rubber thickness).
