What should be paid attention to when selecting buffer strips?

The main function of the buffer strip is to decompose and absorb the impact force caused by falling materials and reduce the damage to the belt. This requires that the buffer strip has good impact resistance, because it is a key factor to determine whether the buffer strip can play its role. In order to have a good impact resistance, the rubber layer of the buffer strip must have a very good elasticity, so that it can fully absorb the impact force when materials fall, and play the role of soft against hard. Only the buffer strip with natural rubber as the main raw material has a high elasticity. The buffer strip made of waste rubber has a poor elasticity, and the impact resistance is even worse. Such buffer strips cannot play a role.

Whether the buffer strip can play a good role in the belt operation mainly depends on the design of the buffer strip, the quality of the material and the advanced technology. A good buffer strip should be reasonably designed, which should be consistent with the belt width, belt speed, height of blanking point, density of medium and other parameters. For example, if the belt speed is greater than 4.5m/s, if a low-molecular-weight buffer strip is used, it will wear very quickly and will not be durable; The material used for good quality buffer strips is also very critical. The rubber layer has high natural rubber content, good elasticity, and strong impact absorption capacity. The rubber layer of poor quality buffer strips has low natural rubber content or even no natural rubber. The elasticity is very poor, and the belt protection is very small. Such buffer strips have very little effect on the use of factories and mines;

What are the advantages of bottom dump trams/ Under what circumstances are bottom dump trams used in coal mine transportation?
