The development history of wear-resistant buffer strips and buffer beds
Buffer beds and buffer strips originated in Germany. They were invented by German engineers in order to reduce energy consumption and improve material transportation efficiency. At first, there were many design styles of buffer beds and buffer strips. The structure is mainly made of aluminum alloy connection, and the length can be continuously adjusted. However, with the needs of practical applications and underground use in mining, its connection structure is gradually replaced by steel structures. In practical applications, German engineers found that aluminum alloy is not strong in steel. , buffer strips often move around, and serious situations can lead to tearing of conveyor belts. The most important thing is that aluminum alloy materials are prohibited from being used underground worldwide. Any aluminum alloy connection structure used underground has potential safety hazards. Therefore, since the 1990s, German engineers have adopted the steel structure connection method. Based on decades of development, they have found that the length has basically been fixed at two specifications. These two lengths more scientifically satisfy the material falling method and practical application. The requirements and structure were gradually determined.
The buffer strip uses an excellent high-elastic special rubber layer to fully and effectively absorb the impact force when the material falls, greatly reducing the impact of the material on the conveyor belt when the material falls, and truly improving the stress at the dropping point. And it uses a special polymer polyethylene surface to reduce the friction coefficient between the conveyor belt and the buffer strip and has good wear resistance. The use of buffer strips ensures that the surface of the conveyor belt is in contact with each other and the force is evenly applied, effectively preventing the longitudinal tearing of the belt caused by the breakage and falling off of the roller, and at the same time greatly reducing the risk of the belt being penetrated by sharp objects or sharp materials. Probability of tearing.
The buffer strip consists of three parts, the wear-resistant layer is ultra-high molecular weight polyethylene, the buffer layer is high-elastic rubber, and the connecting structure is galvanized steel structure (can also be used underground). The rubber is all black, and the wear-resistant layer is ultra-high molecular weight. The color of polyethylene is adjustable, and the most commonly used colors in the market are red, green and black (flame-retardant buffer strips).
Advantages of buffer strips
. The surface contact of the buffer strip conveyor belt effectively prevents damage to the conveyor belt
. The conveyor belt is evenly stressed at the blanking port, which greatly reduces daily repairs and maintenance. Cost
. Effectively eliminate material splashing and leakage caused by uneven stress on the conveyor belt
. The smooth surface of ultra-high density polyethylene reduces the friction of the conveyor belt during operation.
. The arc-shaped design on the surface of the polyethylene layer ensures the smooth operation of the conveyor belt
. The ultra-high elasticity special rubber layer can absorb the impact force of the material to the maximum extent
. Each part of the buffer strip The parts are connected by hot vulcanization process, which is compact and firm
. The design of the underlying structure makes disassembly and assembly easy and fast
