Belt conveyor idler is the most important parts, the tape machine can work with the roller is closely related to the quality.
Roller measure key indicators of good or bad quality of the following eight:
1. Radial runout roller (which targets the stability of a direct impact on material handling.)
2. Axial string momentum (a direct impact on the life of roller)
3. Flexibility (the service life of rollers and the tape of life, and the whole of the drive power)
4. Water resistance (service life of roller)
5. Dustproof performance (the service life of roller)
6. Axial load capacity (service life of roller)
7. Impact resistance (service life of roller)
8. Rotary resistance (life of tape.)
