Rubber Conveyor Belt

EP Rubber Conveyor Belt
- Excellent dimensional stability thanks to low elongation polyester warp yarns
- Custom widths ranging from 300mm to 3500mm are available, depending on the required thickness and roll length.
- Various cover grades allow EP belts to perform reliably in harsh environments — from -60℃ freezing conditions to 300℃ heat, and in contact with oily, flammable, or abrasive materials.
- Its low stretch properties deliver exceptional stability and operational consistency.
- Strong interlayer bonding and superior adhesion between cover and fabric layers enhance belt integrity.

EP Conveyor Belt Tensile Strength Test
In this video, we put our Rubber Conveyor Belt to the test—literally.
To verify the tensile strength of the belt, we secure both ends of a prepared sample using a calibrated clamping fixture.
The testing machine gradually applies increasing force until the belt finally breaks.
At the moment of rupture, the computer records the peak load, giving us the precise tensile strength of the material.
This process ensures our conveyor belts meet the mechanical performance standards required for heavy-duty industrial applications.

Wear-resistant rubber layer for surface protection. - Bounding Rubber:
Ensures strong bonding between steel cords and covers. - Steel Cord:
High-strength galvanized wires for load bearing and low elongation. - Bottom Cover:

ST Conveyor Belt Tensile Strength
The principle of testing the tensile strength of a steel cord conveyor belt is similar to that of testing the tensile strength of an EP conveyor belt. However, since the steel cord can withstand greater tension, a larger clamp is required to clamp the conveyor belt, as shown in the figure, or another clamp fastened by screws.

NN Conveyor Belt Tensile Strength
This test demonstrates the tensile strength of our NN Conveyor Belt.
A standard sample is cut and placed into a calibrated tensile testing machine.
Both ends are clamped securely to ensure accurate results.
The machine applies steady pulling force until the belt breaks.
At the point of failure, the system records the maximum load the belt can withstand.
This value reflects the actual tensile strength of the material.
The process helps confirm that our NN Conveyor Belts meet the mechanical requirements for demanding industrial use.

Rubber Conveyor Belt Engineering & Reliability
Our rubber conveyor belts are designed for strength, precision, and long-term reliability. Engineered with advanced materials, they ensure smooth operation under demanding industrial conditions.
How Does the Conveyor Belt Prevent Elongation?
Our belts feature steel cord or polyester-nylon reinforcements that prevent elongation. This ensures consistent tension and stable performance, reducing the need for frequent adjustments in long-haul applications.
How does the belt resist fire and static buildup?
Our flame-resistant rubber compounds meet ISO 340 standards, while the anti-static features help dissipate charge buildup, preventing safety hazards in environments like coal mines and grain storage areas.
How does the belt handle heavy loads?
Our belts use high-tensile steel cord made from multiple high-strength wires, providing superior load-bearing capacity and durability, allowing the belt to handle heavy loads without compromising performance.
What enhances belt flexibility in complex layouts?
The use of high-flexibility carcass materials allows our belts to handle tight turns and curves without cracking or causing stress. This design ensures better durability in challenging conveyor paths.
What prevents material spillage and edge wear?
Our belts are equipped with reinforced sidewalls and high-abrasion resistant rubber. This prevents material spillage and edge wear, ensuring a clean material transport process in mining, cement, and other bulk material applications.
How is belt traction on pulleys improved?
We use optimized rubber compounds with precision-engineered textures to increase traction, preventing slippage and improving efficiency in applications where consistent material flow is required.
