Cold Resistant Conveyor Belt

YUFENG specializes in R&D, production and customization of Cold Resistant Conveyor Belts for ultra-low-temperature applications. Through optimized rubber formulations, structural design and field testing, our belts maintain flexibility, elasticity and structural integrity in extreme cold while reducing the risk of cracking, delamination and breakage. A full-process quality control system and standardized low-temperature cycling tests ensure consistent performance and international industrial application requirements.

Materials & Manufacturing

1. Cold-Resistant Cover Rubber

YUFENG Cold Resistant Conveyor Belts use a composite natural rubber and polybutadiene rubber formula with specialized low-temperature plasticizers and anti-cracking additives. The low-temperature embrittlement point is 10–15℃ below the rated operating temperature, helping prevent cracking during low-temperature impact. Abrasion loss is ≤180mm³, maintaining wear resistance under cold operating conditions.

2. Cold-Resistant Carcass

The carcass uses specially treated low-temperature EP polyester canvas combined with a cold-resistant bonding process. The canvas fibers retain structural strength at temperatures down to -55℃, while inter-layer adhesion at low temperatures reaches ≥2.0N/mm. The structure also provides good low-temperature troughability for stable material conveying.

3. Customized Structural Options

For different cold-region applications, YUFENG provides customized structures including oil-and-cold-resistant, flame-retardant-and-cold-resistant, tear-resistant reinforced and cold-resistant steel cord conveyor belts. These options are suitable for conveying heavy loads, corrosive materials and sharp materials in complex environments.

Cold-Resistance Grade Specifications

YUFENG Cold Resistant Conveyor Belts are available in three low-temperature grades for different operating conditions. The following performance parameters have been verified through factory testing and practical applications.

Rubber Cover Grade & Standard Specifications

Cover Physical Property Indexes

Low-Temperature Performance

1. Cold-Resistant Coefficient

The cold-resistant coefficient at elongation is ≥0.3 for C1 at -45℃ and ≥0.2 for C2 at -50℃, supporting stable belt flexibility and mechanical performance under low-temperature conditions.

2. Applicable Temperature Range

C1 is designed for temperature conditions from -45℃ to +50℃, while C2 is designed for temperature conditions from -60℃ to +50℃. Actual grade selection should be based on the minimum operating temperature, material characteristics and conveying conditions.

Dimensions & Manufacturing Options

1. Standard Customizable Dimensions

Belt widths are available from 500–3200mm, with 3–8 canvas plies and total thicknesses from 5–30mm. Molded sealed edges are also available according to application requirements.

2. Standards & Test Documentation

All specifications comply with GB/T 7984 and applicable international industrial standards. Factory low-temperature test reports and related quality documentation can be provided with shipment.

Quality Control & Global Supply

1. Factory Testing & Quality Verification

YUFENG follows standardized production and testing procedures for cold-resistant conveyor belts. Performance data and product quality documentation can be provided for customer verification and project requirements.

2. International Application

YUFENG Cold Resistant Conveyor Belts are supplied to more than 30 countries and regions with cold climates, serving applications including outdoor operations, open-pit mining and bulk material handling at ports. Production and testing processes follow applicable standards including DIN 22102, ISO 4195, SGS and BV requirements.

Field Testing & Performance Comparison

1. 12-Month Low-Temperature Field Test

To verify low-temperature performance under actual working conditions, YUFENG conducted a comparative field test at an open-pit coal mine in Northeast China. The test environment had average winter temperatures of -25℃ to -35℃, with extreme lows reaching -42℃, while the conveying equipment operated approximately 18 hours per day.

2. Comparison with Standard Conveyor Belts

Standard conveyor belts began to harden and lose elasticity after one month of low-temperature operation. Surface cracking appeared after two months, followed by belt breakage after approximately three months, resulting in frequent replacement during winter.

YUFENG C2-grade Cold Resistant Conveyor Belts maintained stable flexibility throughout the six-month winter cycle, with no visible hardening, cracking or delamination. The customer reported stable equipment operation and reduced annual belt procurement and maintenance costs by 65%.

Real Customer Application Cases

1. Open-Pit Coal Mine Project in Northeast China

The mine previously used standard conveyor belts that required replacement every 3–4 months during winter. Frequent low-temperature belt failures caused additional downtime and maintenance costs. After switching to YUFENG C2-grade Cold Resistant Conveyor Belts, the equipment operated continuously for 18 months without reported low-temperature failures. Winter downtime was reduced by 90%, with annual parts and labor savings exceeding $45,000.

2. Bulk Material Port Terminal Project in Siberia

The Siberian port operates in extreme winter conditions, with temperatures dropping to -50℃. The customer previously used imported conveyor belts with higher procurement costs and an average service life of approximately eight months. YUFENG supplied customized C3-grade heavy-duty Cold Resistant Conveyor Belts for long-distance outdoor conveying. After passing local third-party low-temperature testing, the belts operated continuously for 14 months without cracking or breakage, leading to repeat orders for two additional port conveyor lines.

Key Target Industries

1. Mining & Coal

Suitable for outdoor material conveying in open-pit coal mines and metal mines operating in cold regions, particularly during winter.

2. Ports & Terminals

Designed for bulk material handling at high-latitude ports and northern terminals where conveying systems operate under prolonged low-temperature conditions.

3. Cold Storage & Food Processing

Applicable to low-temperature conveying systems for quick-frozen food processing, cold storage facilities and related material handling operations.

4. Construction Materials

Suitable for winter material transportation at construction sites, aggregate plants and cement facilities in cold regions.

5. Chemical & Power Industries

Used for conveying fly ash, bulk chemical materials and other industrial materials at chemical plants and power stations exposed to low-temperature environments.

FAQ

Q1: How do I choose the right cold-resistance grade (C1/C2/C3)?

Grade selection is primarily based on the local minimum winter ambient temperature; we recommend a safety margin of 10–15°C to account for extreme temperature drops. C1 is suitable for regions with standard cold winters (minimum -25°C); C2 is suitable for severely cold regions (minimum -40°C, such as Northeast China and most of Russia); C3 is suitable for extreme cold regions (down to -55°C, such as Siberia and Northern Canada). We offer precise, one-on-one selection recommendations based on specific operating conditions.

Q2: What is the actual service life of YUFENG cold resistant conveyor belts?

Service life depends on the low-temperature environment, material abrasiveness, and routine maintenance. Based on 18 years of global project data: C1 lasts 18–24 months in moderately cold regions; C2 lasts 12–18 months in severely cold mining and ore-handling operations; and C3 operates stably for 10–14 months in extreme cold environments (-55°C). Compared to standard conveyor belts, the winter service life is 2–3 times longer, significantly reducing replacement frequency and downtime losses.

Q3: Is customization available? What are the policies for samples and minimum order quantities (MOQ)?

YUFENG supports customization for all scenarios. This includes functional formulations (e.g., oil/acid/alkali-resistant + cold-resistant, or flame-retardant + cold-resistant) and structural customizations (e.g., rip-stop features, steel cord reinforcement, and sealed edges). Belt widths can be customized anywhere between 500mm and 3200mm. There is no minimum order quantity (MOQ) for samples; we provide 1–2 meters of free test samples (customer pays shipping only), with a turnaround time of 3–7 days. The MOQ for standard specifications is 100 meters, while custom specifications require 500 meters; mass production lead times range from 10 to 25 days.
