Questions and answers on grinding technology - Metso

17/10/2018  The way to monitor for problems would be to try to get a better picture of exactly what is happening inside the mill. This can be done in several ways. One method would be to monitor the noise levels within the grinding mill using Acoustic technology which measures steel on steel impacts within the mill. By measuring the noise levels within the mill, you can adjust the mill speed to compensate ...

Controlling Noise on Construction Sites

A cost-effective way to reduce noise at a construction worksite is to buy quiet equipment. When buying equipment always ask if there is a quieter way of doing the job. All things being equal most contractors would choose a quieter machine or process. Quieter machines or processes can cost more. Manufacturing tolerances are tighter, gears mesh better, quieter cooling fans are used, etc. Because ...

principles of noise control planning. A more precise way is to use immission and emission values in frequency bands as follows. The desired (least annoying) octave band frequency spectrum for which to aim at the location of the exposed worker is shown in Figure 10.1 for an overall level of 90 dB(A). If the desired level after control is 85 dB(A), then the entire curve should be displaced ...

Wind Turbine Noise Solutions - Alternative Energy News

Wind turbine manufacturers are working on many ways to reduce the noise, like noise-reduction-oriented blade redesign or flow control. Wind turbine noise management is receiving a lot of attention for the RD community. In response to Stan Francis the only issue with your idea is the amount of energy required to compress the air. Air ...

Control Valve Noise Problems - Instrumentation Tools

One way to reduce noise output is to use special valve trim resembling the trim used to mitigate cavitation. A common cage-guided globe valve trim design for noise reduction uses a special cage designed with numerous, small holes for process gas to flow through. One of the ways in which these small holes reduce audible noise is by shifting the frequency of that noise upward. This increase in ...

Troubleshooting Tips: Diagnosing and Mitigating Noise

16/05/2012  During a commissioning of a mill there were problems with noise spikes on encoder signals. After looking at the conduit trays under the seal plates we found that 400 VAC wires were run in the same tray as low voltage PLC signal and encoder cable. The contractor only had one type of multi-conductor cable (white exterior insulation) so the motor fan wires were the same type cable as the 24

Wind turbine noise: the facts and the evidence

In a paper titled Wind Turbine Noise, Infrasound and Noise Perception by Anthony L. Rogers, Ph.D., Renewable Energy Research Laboratory University of Massachusetts at Amherst USA, 2006/01/18, Rogers stated that as a rule of thumb, three times blade tip height from a turbine to a residence gives acceptable noise levels. I believe that this rule is used in Denmark, where there seem to be ...
