Abstract
The fire retardant buffer for conveyer belt consists of at least two buffering chutes set in parallel on support racks in certain interval. The buffering chutes have the same length direction as the carrying area of the conveyer belt and channel cross section. On the buffering chutes, one buffering cushion with support surface layer comprising ceramic plates or GRP plates is set. The conveyer belt running inside the chutes has less deviation, the buffering cushion absorbs the impact energy of the falling material, and the support surface layer of ceramic plates or GRP plates is wear resistant and fire retardant and may be also used in mine with inflammable and explosive gas.
