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.

ST Conveyor Belt Construction
- Top Cover:
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:
Protects the belt underside from friction and wear.
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 Rubber Conveyor Belt
- Constructed with nylon-nylon fabric for high elasticity and flexibility.
- Runs smoothly on small pulleys without cracking or deformation.
- Excellent troughability for secure and stable material flow.
- Lightweight structure improves energy efficiency of the conveyor system.
- Strong impact absorption makes it ideal for drop loading conditions.

NN Conveyor Belt Construction
- Top Cover Rubber:
Protects the belt surface from abrasion, impact, weather, and harsh material contact. - NN Fabric:
Reinforced nylon in both warp and weft ensures flexibility, strength, and good load-bearing capacity. - Adhesive Glue:
Strong bonding layer that tightly connects rubber and fabric, preventing internal separation or delamination. - Bottom Cover Rubber:
Provides underside protection from rollers, pulleys, and wear caused by constant running contact.
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.
