Conveyor Impact Bar structure:
The Conveyor Impact Bar is made of buffer tape (commonly known as blackboard) and ultra-high molecular weight polyethylene (UHMWPE) by hot vulcanization process.
The Conveyor Impact Bar is made of metal skeleton and rubber by thermal vulcanization.Generally, the metal skeleton is made of c-section steel and aluminum alloy. The skeleton is mainly used to connect the support of the buffer press.We are equipped with anti-loose bolts to ensure that the buffer strip is firmly fixed to the buffer support and can withstand impact for a long time without loosening.
