What are the basic conditions that a qualified conveyor belt should meet?

Apr 15, 2021

Conveyor belt is an important part of conveyor. In the cost of conveyor components, the cost of the conveyor belt accounts for nearly half of the entire equipment cost. During the operation of the conveyor, the load that the conveyor belt bears is very complicated. In addition to the longitudinal tensile stress, it is also subjected to the bending stress of the roller and the idler. Most of the conveyor belt’s failure is manifested as work. The surface layer and edges are ground roots, and the impact of large and sharp materials causes breakdown, tearing and braking. Therefore, a reasonable choice of conveyor belts is very important for conveyor design.

The selection of the conveyor belt is carried out according to the line layout of the conveyor, the conveyed materials and the conditions of use. Reasonable choice of conveyor belt is not only essential to complete the conveying task of the conveyor, but also affects the design of mechanical parts such as conveyor rollers, idlers and moving devices. The following briefly introduces the basic conditions for the conveyor belt to reach:

conveyor belt

1. It must have sufficient tensile strength and elastic modulus to achieve the required transmission power within the required distance, the required transmission power, and the operating elongation caused by the load allowed to be loaded.

2. It must have good load support and sufficient width to meet the type and volume required when transporting materials.

3. It must be flexible, the purpose is to bend around the drum in the length direction. If necessary, it is desirable to form a groove shape in the transverse direction.

4. There must be dimensional stability to make the conveyor belt run smoothly.

5. The covering rubber on the bearing surface must withstand the load impact of the bearing object. Once it can help restore elasticity, the covering rubber can have enough friction with the roller during transmission.

6. There is good adhesion between the components to avoid separation.

7. Good tear resistance and damage resistance.

8. It can be connected into a ring.

9. Under some specific working conditions, the conveyor belt is required to have abrasion resistance, heat resistance, flame retardancy, and oil resistance. Food conveyor belts should be kept clean.
