The Material and Main Performance of the Idler

The material and main performance indicators of the idler rollers are as follows:

Materials: Common conveyor roller materials include steel, rubber, ceramic, nylon, and polymer composite materials, among others.

Main performance indicators:

Load capacity: For coal conveying lines with large throughput and heavy loads, rollers with strong load capacity should be selected, such as rollers with larger diameters and thicker walls.

Rotational flexibility: Flexible rotating rollers can reduce the operating resistance of the conveyor belt and lower energy consumption.

Radial runout and axial movement: Rollers with low radial runout and axial movement can ensure the smooth operation of the conveyor belt and reduce the occurrence of belt misalignment.

Corrosion resistance and anti-aging properties: In humid or corrosive environments, nylon rollers or steel rollers with anti-corrosion treatment are more suitable.

Wear resistance: For coal with larger particle size and higher hardness, it is necessary to choose wear-resistant rollers, such as ceramic rollers or polymer rollers.

Hardness: The hardness of nylon rollers is typically expressed in Shore Hardness, generally ranging from 70A to 95A.

Surface roughness: The surface roughness of nylon rollers directly affects the friction and transmission effect with the contact material; typically, a smooth surface with a low roughness value is required.
