Noise reduction in chains and sprockets

By applying this special low-noise sprocket, noise reductions of 7-8 dB are obtainable. These sprockets can only be applied to conveyor chains. From a cost point of view, sprockets are usually the cheaper components and therefore it is more interesting to make the noise-reducing changes to the sprockets instead of to the relatively expensive chain.

Conveyor Noise Specification and Control

conveyor noise issues due to wear of components. Preliminary Conveyor Noise Tests Early investigations included the measurement and analysis of farfield conveyor noise. Noise emanating from typical sections of 8000 TPH and 10000 TPH conveyors was recorded and analysed to produce narrowband and time domain plots. Figure 2 shows a

Conveyor Jam-Up - iSixSigma

25-08-2005· Boxes/crates vibrate along the rollers of the conveyor and sometimes end up crooked or to one side of the conveyor, or a curve in the conveyor causes this to happen. When the boxes/crates reach curves further down the conveyor, they sometimes stick at the bend of the curve and cause log-jams. Presently we use diverting arms to keep product ...

HSE - Noise: Sound Solutions Case Studies

Reducing noise in a drag-line cab (case study #25) A company using tracked drag-lines in quarrying found that drivers were being exposed to A-weighted noise levels of 96 to 100 dB. The particular problem was that the main drive engine was located in the same all steel 'box', separated from the driver's cab only by a sheet steel bulkhead containing a door.

Gearbox Reducer Vibrations: Reducing Conveyor Drive Noise

22-12-2011· Isolate gearbox reducer noise by using sound boxes lined with noise-absorbing materials.
