缓冲托辊重量轻，旋转惯性小。托辊专用高分子材料重量轻，比重是钢材的七分之一，用这种材料制成的托辊，重量是普通托辊的二分之一左右，旋转惯性小，JDG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具托辊与皮带之间的摩擦小。缓冲托辊安装在输送机受料段的下方，减小落料时物料对输送带的冲击，以廷长输送带的使用寿命.缓冲托辊的间距一般100-600毫米。
The buffer idler has light weight and small rotation inertia. The special high polymer material for supporting roller is light in weight, and its specific gravity is one seventh of that of steel. The supporting roller made of this material is about one half of that of ordinary supporting roller, with small rotation inertia and small friction between supporting roller and belt. The buffer idler is installed under the receiving section of the conveyor to reduce the impact of materials on the conveyor belt during blanking, so as to prolong the service life of the conveyor belt. The spacing of the buffer idler is generally 100-600mm
