缓冲托辊在安装方面一是提高安装的密度；二是经常检查，及时更换损坏的托辊。对于落料落差较大的输送带建议安装缓冲锁气器，将缓冲托辊用缓冲床代替。在选购方面根据缓冲托辊的特点提出一下几点注意事项：托辊径向跳动量、托辊灵活度、轴向窜动量、托辊防尘性能、防水性能、托辊轴向承载性能、托辊抗冲击性能等。
In the installation of buffer idlers, one is to increase the installation density; the other is to check regularly and replace damaged idlers in time. For conveyor belts with large blanking drop, it is suggested to install buffer air lock and replace buffer roller with buffer bed. According to the characteristics of cushioning idler, the following points for attention are put forward: radial jump of idler, flexibility of idler, axial channeling, dust-proof performance, waterproof performance, axial bearing capacity of idler, impact resistance of idler, etc.
