Performance characteristics of idlers
Drag reduction and efficiency enhancement: Rollers generate more than 70% of the total resistance in conveyors. High-quality rollers can lower the coefficient of friction, thereby reducing energy consumption. For instance, polymer rollers boast a low coefficient of friction, significantly boosting conveying efficiency.

The Structure and Operating Principle of the Roller
The drum is primarily composed of a bearing housing, bearings, and baffles. Its working principle is based on frictional rotation—specifically, using rolling friction instead of sliding friction to minimize energy loss—and power transmission is achieved through the movement of a drive belt.

The functional features and applications of rollers
High transmission efficiency: The large friction between the roller and the conveyor belt or other materials ensures high transmission efficiency, minimizing energy loss.

Classification and Functions of Idlers
Buffer idlers: Installed beneath the material-receiving section, these components absorb material impact via structures such as spring plates and rubber rings, helping to extend belt life. They are ideal for applications with frequent material discharge, such as power plants and cement factories.

Roller bearings are the core components of belt conveyors.
The idler consists of a tube body, central shaft, bearings, and seals. Some specialized types (such as cushioned idlers) are equipped with spring plates or rubber rings to enhance shock-absorbing performance. Their design must strike a balance between strength and lightweight construction—for instance, polymer-material idlers weigh only half as much as their steel counterparts, reducing rotational inertia and minimizing friction with the conveyor belt.
