At present, steel cord conveyor belts have been widely used in coal mines, mines, ports, electric power, metallurgy, building materials and other working conditions industries. They are mainly used to convey materials that require tear resistance. They have high tensile strength, long life, and It can be used for long-distance, large-span, long-distance, and high-speed material transportation, but it will also be damaged and hit by heavy blows during use. Failures such as wear, longitudinal cuts or tears can cause serious economic losses.
Through the impact process test, in-depth analysis of the factors affecting the impact strength of the tear-resistant rubber belt.
The main indicators for measuring the performance of steel wire belts: mainly include the rated tensile strength, wear resistance, tear strength, impact strength, etc. For steel wire rope core conveyor belts, the main bearing body for longitudinal stretching is steel wire ropes, and different rated tensile strengths are used. For tensile strength, steel wire rope cores of different diameters and structures need to be selected. There are many factors that affect the tear strength and impact strength of the belt, such as the diameter and spacing of the transverse steel ropes, the performance of the covering rubber, the thickness and the spacing of the longitudinal steel rope cores, etc.
Through the analysis of the results of the comparative test, the final conclusion is reached: the external impact resistance of the steel cord conveyor belt is basically linear with the energy. The thickness of the cover rubber is the main factor affecting the impact strength of the belt. The double weft is better than the single weft. The reinforcement can further improve the impact resistance of the steel wire rope conveyor belt, and at the same time, its impact resistance will increase with the improvement of the physical properties of the covering rubber.
