缓冲托辊表面由冷钻接连体弹性胶环和锁环构成，缓冲托辊安装在输送机受料段的下方，减少输送带所受的冲击，延长输送带使用寿命zmjt049。缓冲托辊主要起缓冲作用。
The surface of buffer idler is composed of elastic rubber ring and lock ring connected by cold drill. The buffer idler is installed below the feeding section of conveyor, which reduces the impact on conveyor belt and prolongs the service life of conveyor belt zmjt049. The cushioning roller mainly plays a cushioning role.
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，缓冲托辊主要针对洗煤厂、焦化厂、化工厂等腐蚀性环境而研制的一类托辊。
Buffer idler is used to reduce the impact of blanking on conveyor belt at the feeding place of belt conveyor. Buffer idler is a kind of idler developed for corrosive environment such as coal washery, coking plant and chemical plant.
缓冲托辊本身具有的韧性是普通金属的10倍以上，缓冲托辊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。缓冲托辊的间距一般100-600毫米。（中煤集团）
Buffer roller itself has more than 10 times the toughness of ordinary metal, the life of buffer roller is five times that of traditional pillar shoes, corrosion resistance, flame retardant, antistatic, light weight and other characteristics, which are widely used in mining. Buffer roller spacing is generally 100-600 mm. (China Coal Group)
