Belt or Roller Conveyor? | Cisco-Eagle
Oct 22, 2019 When is a belt curve your best option? The main reason you’d specify a belt curve is usually the same one you would use to specify a belt conveyor rather than a roller: belts can handle different load types of loads and control them better than rollers. When a product’s position and orientation are critical, belt conveyors are a better ...

It was also determined that running the conveyor in wet conditions reduced the sound level significantly. A urethane coating was used to treat the conveyor flight bars in order to reduce the impact noise as the bars passed around the conveyor deck. Based on the major improvements that have been made since the 1980s in urethane coatings, urethane was chosen to coat the dominant noise sources on the conveyor.

Plant Engineering | Limiting noise from conveyor rollers
Dec 10, 2003 A noisy conveyor system running through a facility can emit high decibel levels all along its route, creating a major noise problem for a large portion of the plant. There are two ways that traditional conveyor rollers contribute to noise pollution: the first is the bearings in the rollers; the second is the fit between the rollers and the frame holding them.

Engineers turn down conveyor noise
Mar 26, 2001 Noise levels generated by a typical lineshaft conveyor system-whose sources of noise include shaft clatter, bearing rattle, and roller tube ringing-can exceed 70 dBA. By applying various noise reduction strategies in this newest generation of conveyor systems, engineers have been able to achieve decibel levels in the low 60's-all the more impressive when you consider that decibels are logarithms of noise levels.
