How to choose the thickness of conveyor belt?
The selection of conveyor belt thickness needs to consider a number of factors, the following are some key points:
Conveying material characteristics
- Weight: the heavier the material, the greater the pressure, the thicker the conveyor belt should be selected, such as transporting heavy materials such as iron ore, the conveyor belt can be 12-20mm thick.
- Shape and hardness: sharp, angular or hard material easy to wear conveyor belt, like conveying crushed ore, should choose more than 10mm thick and wear-resistant conveyor belt; For conveying small particles and soft materials such as flour, a thinner conveyor belt can be selected.
Delivery distance and speed
- Distance: for long distance transportation, the conveyor belt is subject to large tension, in order to prevent tensile deformation and fracture, it is necessary to choose thicker, such as the distance of more than 500 meters, it is recommended to choose more than 8mm thickness.
- Speed: In a fast conveying system, the conveyor belt should withstand greater impact, such as a speed greater than 3m/s, it is appropriate to choose a conveyor belt with a thickness of 8mm and above to ensure strength and stability.
Working environment
- Temperature: the high temperature environment will reduce the performance of the conveyor belt, low temperature will make it hard and brittle, in the high temperature environment such as 100℃ above the steel mill, need to choose high temperature resistant thick conveyor belt, the thickness is generally more than 10mm; In low temperature environment, it is also necessary to choose the appropriate thickness to ensure flexibility.
Humidity and chemical corrosion: wet or chemical corrosion environment, will affect the life of the conveyor belt, in such an environment, in addition to the selection of corrosion-resistant materials, can also be appropriate to increase the thickness, such as in the plating factory and other environments, can choose more than 8mm thickness of the conveyor belt.
Equipment requirements
- Drum diameter: The diameter of the drum is small, the bending degree of the conveyor belt is large, easy to fatigue damage, if the diameter of the drum is small, such as less than 200mm, should choose a thinner conveyor belt, generally 6-8mm, to improve flexibility and reduce damage.
- Tension: the system with high tension force, the conveyor belt needs to have sufficient thickness and strength to withstand, if the tension is large, the conveyor belt with a thickness of more than 10mm can be selected.
Cost and efficiency
- Cost: As the thickness increases, the cost of the conveyor belt rises. On the basis of meeting the requirements of use, the cost should be balanced. If the budget is limited and the conveying requirements are not high, the thinner standard thickness conveyor belt can be selected.
- Efficiency: Although the thick conveyor belt has a strong carrying capacity, it may affect the running speed and flexibility. For occasions where rapid conveying is required, a relatively thin conveyor belt can be selected to improve the conveying efficiency under the premise of ensuring the carrying capacity.
