缓冲托辊(impactidler)，缓冲托辊用于带式输送机受料处减缓落料对输送带的冲击，主要针对洗煤厂、焦化厂、化工厂等腐蚀性环境而研制的一类托辊，它本身具有的韧性是普通金属的10倍以上，寿命为传统柱鞋的五倍，耐腐蚀阻燃，抗静电，自重轻等特点，广泛用于矿山开采。托辊辊体专用的高分子材料，其机械性能类似于青铜，具有很好的耐磨性，而且具有良好的自润滑性能，不伤皮带。缓冲托辊防腐性能优越。辊体及密封件都用高分子材料制作，耐腐蚀。在腐蚀性场合使用，使用寿命可达到普通托辊的5倍以上。
Impact roller is used to slow down the impact of blanking on the conveyor belt. It is mainly developed for coal washing plant, coking plant, chemical plant and other corrosive environment. Its toughness is more than 10 times that of ordinary metal, and its service life is five times of that of traditional pillar shoes. It is widely used for corrosion resistance, flame retardant, antistatic and light weight Mining. The special polymer material for roller body has good wear resistance, good self-lubricating property and no damage to the belt. The anti-corrosion performance of buffer roller is superior. Roller body and seal are made of polymer material, corrosion resistance. The service life of the roller can reach more than 5 times of that of the ordinary roller when it is used in corrosive situation.
