Description

As the awareness of safety and economy for mining further increases, the requirements for belt conveyors are higher and higher, where belting is of the highest importance. The Impact idlers are traditionally used to protect belts around the chute, however, which has several disadvantages,e.g.,too many rotating parts, too much maintenance, jams of big block of materials and small shock surface. We have developed a new-typed buffer bed, which can overcome these shortcomings. The Impact bed is of wide support surface and even strength, which can guarantee the surface contact of belts and reduce the belt sagging and materials spilling effectively. Moreover, the longitudinal tear of belts, which is caused by breakage and drop of idlers, can be prevented effectually, while the belt tear caused by sharp instruments or material can be reduced. For there is no rotating parts in impact beds, the regular maintenance is no longer required, and the operation cost goes down greatly .
