Do you know how to control the noise generated by crushing machines? Now let's choose together.
Reduce Sound Source Noise:
, Equipment Regular Troubleshooting: Machine failure will lead to additional noise, such as belt deviation will lead to the sound of product belts hit, such as discharging problems, excessive rock break the noise generated by the crusher, machine foundation descent will lead to machine resonance noise. If such noise occurs, technical personnel should be contacted as soon as possible to solve the problem and avoid greater losses.
2, equipment technical improvement: select low noise equipment as far as possible, to solve the problem of large noise fundamentally, or improve the accuracy of mining machinery processing and assembly, to reduce mechanical vibration and friction noise; high-pressure, high-speed air flow to reduce pressure difference and flow rate, or change the shape of air nozzle. Control on the Way of Propagation:
in the overall layout of reasonable design: Planning production sites, the main noise source workshop or noise equipment away from the quiet requirements of the workshop, laboratory, office, etc.
uses barriers to prevent noise transmission: artificial barriers can be added, or natural barriers, such as hills, slopes, forests, grasses or buildings, to absorb and prevent part of the noise.
uses the directional characteristics of sound sources to control:
, such as the use of sound absorption cotton to isolate noise transmission: fan outlets, air compressors and other outlets toward the open air or sky, to reduce environmental impact.
Protection for Noise Acceptors:
For workers working in noise environment for a long time, adopt a variety of protective measures, such as wearing earplugs, earmuffs, helmet and other anti-noise supplies; take workers rotation operation, shorten the working hours of workers entering high noise environment, to reduce noise on the health of workers. Harm. More than
is the way to control the noise generated by crushing machines, and I hope it can help you. Eight hundred and eighty-eight thousand one hundred and eleven
