At Monster Belting, each steel cord conveyor belt is engineered with precision and care to meet the toughest operational demands. From their innovative construction to their resilient belt joints, every element contributes to long-lasting performance that industries can rely on. 

Characteristics: 

1. Our products are characterized by high tensile strength and suitable or sine machine with large span and material transportation with long distance.
2. Due to small tensile, our products could be stained with a small travel distance.
3. The driving roller with small diameter: the belt core takes vertically arranged steel wire rope as framework, which could resist flexing.The machine could be equipped with driving rollers of small diameter, which could make the machine more compact.
   4. Adhesion of rubber and steel wire rope: galvanize the surface of the steel wire rope and use excellent adhesive sizing material to make steel wire ropes stick together. They are impact resistant, strongly adhesive. Moreover, they have a long service life.
4. The tensile of steel wire ropes are well distributed: Due to advanced manufacturing technology, steel wire ropes are well distributed, which keeps an average tensile, stable operation and less deviation.

Steel core Conveyor Belt Construction

High Tensile Strength and Load Capacity 

The use of high-carbon steel cords gives these belts exceptional tensile strength. They can carry large loads over extended distances without failure, maintaining stability even under intense mechanical stress. 

The performance differences between EPDM (Ethylene Propylene Diene Monomer) and SBR (Styrene Butadiene Rubber) in terms of heat resistance at 200°C are quite significant. Here’s a breakdown of their characteristics and differences when used in high-temperature applications like conveyor belts:

EPDM (Ethylene Propylene Diene Monomer)

• Heat Resistance: EPDM is well known for its excellent heat resistance, especially at higher temperatures. It can handle continuous exposure to temperatures of up to 150°C and short peaks of 200°C without significant degradation. 
• Chemical Resistance: EPDM excels in resisting alkalines, acids, water, and steam. This makes it ideal for applications involving chemical exposure, steam, or high-moisture environments. 
• Flexibility: It maintains its flexibility at higher temperatures compared to SBR. 
• Applications: Commonly used in environments that involve water, steam, or extreme weather (e.g., HVAC systems, automotive gaskets, or high-heat industrial applications). 
• Key Benefits for 200°C Heat Resistance: 
• High resistance to oxidation and aging 
• Better at handling sustained exposure to heat without degrading 
• Superior performance at 200°C compared to SBR. 

SBR (Styrene Butadiene Rubber)

• Heat Resistance: SBR generally has lower heat resistance compared to EPDM. For continuous exposure, it can handle temperatures up to about 120–150°C but can handle short peaks of around 180°C. 
• Chemical Resistance: SBR offers good abrasion resistance but is more susceptible to degradation under exposure to oils, fuels, or extreme weather conditions compared to EPDM. 
• Flexibility: SBR provides excellent wear resistance but loses flexibility at higher temperatures, which is less ideal in high-heat environments. 
• Applications: SBR is often used in environments where abrasion resistance is critical, but where heat exposure is less intense (e.g., conveyor belts in industrial environments, automotive tires). 
• Key Benefits for 200°C Heat Resistance: 
• While it can tolerate short temperature spikes, prolonged exposure to 200°C will likely cause hardening, cracking, and deterioration over time. 
• Less suitable than EPDM for applications involving constant high heat exposure. 

For cement clinker, which typically has a temperature ranging from 100°C to 200°C, EPDM (Ethylene Propylene Diene Monomer) is indeed a suitable material for this application, especially for temperatures up to 200°C. 

EPDM has excellent heat resistance and can withstand continuous exposure to 150°C with short peaks of up to 200°C without significant degradation. This makes it a good choice for conveying hot materials such as cement clinker. Additionally, EPDM’s resistance to steam, moisture, and its flexibility at high temperatures further enhances its suitability for handling clinker in cement production processes. 

However, it’s important to ensure that the EPDM formulation used is specifically designed for high-temperature applications to maintain durability and performance. In some cases, a higher heat-resistant grade of EPDM may be required for continuous exposure at or near 200°C. 

Property	EPDM	SBR
Continuous Heat Resistance	Up to 150°C; short peaks up to 200°C	Up to 120-150°C; short peaks to 180°C
Chemical Resistance	Excellent (resists steam, water, acids, alkalis)	Fair (susceptible to oils and fuels)
Flexibility at High Temperatures	Maintains flexibility well at higher temps	Loses flexibility at higher temps
Durability at 200°C	Good, minimal degradation	Poor, can lead to cracking and hardening
Typical Applications	High heat, steam, and chemical environments	Abrasion-heavy but lower heat exposure

 

• EPDM is the better choice when heat resistance at 200°C is required for extended periods. It maintains its flexibility and chemical resistance under high heat conditions. 
• SBR, while effective in general abrasion resistance and lower heat environments, is less durable at 200°C for prolonged use and can degrade faster than EPDM. 

For 200°C heat-resistant conveyor belts, EPDM would be the superior option due to its better long-term performance and resistance to aging at higher temperatures. 

Superior Adhesion and Bonding 

One of the key advantages of steel cord conveyor belt construction is the advanced bonding process. The steel cords are carefully coated and embedded within rubber layers, ensuring a strong, uniform bond. Monster Belting employs advanced vulcanization techniques that enhance adhesion, preventing delamination and ensuring long-term reliability.

Enhanced Resistance to Impact and Tearing 

The layered structure provides superior resistance to cuts, tears, and punctures. This is especially beneficial in industries handling sharp or abrasive materials. 

Longevity in Harsh Environments 

Built for resilience, these belts perform exceptionally well in extreme temperature ranges, moisture-heavy settings, and high-impact environments—ensuring reduced downtime and lower maintenance costs. 

Understanding the Steel Cord Belt Joint Process 

Importance of a Strong Belt Joint 

The steel cord belt joint plays a crucial role in maintaining the integrity of the conveyor system. A weak or improperly aligned joint can lead to belt failures, reduced efficiency, and unplanned maintenance. Therefore, professional jointing ensures uniform load distribution and consistent performance. 

Types of Steel Cord Belt Joints 

1. Mechanical Joints: Quick to install but suitable mainly for temporary applications. 
2. Vulcanized (Spliced) Joints: Offer higher strength, smoother operation, and are preferred for long-term use in heavy-duty operations.
