Extend Mine Viability through Sound Attenuation

Sound Attenuation

MINETEK is a globally recognized leader in the provision of sound attenuation and noise management solutions enabling OEMs and mining operations to have the world's quietest machinery. With over 1,200 installations across more than 90 different OEM-approved models, our solutions keep your equipment moving quietly and within regulatory and community expectations, all without compromising machine integrity, airflow, maintenance or operating ability. MINETEK's sound attenuation solutions have been developed for over 25 years. We've delivered the world's quietest mining machines with a global site install team delivering noise reductions of up to 50%. 

What is Sound Attenuation:

Sound attenuation is a damping of sound, an interruption that diminishes the volume and quality of the sound wave. This reduces how far sound travels.

Why do we need Sound Attenuation:

By reducing the sound output of mining machinery, several benefits can be achieved:

  • The machinery can work closer to the sound monitors on the mine sites boundaries.
  • The reduction in mining noise keeps communities onside.
  • Increased mining operating times
  • Operator safety

How does Sound Attenuation work:

Sound Attenuation can be achieved by combining these principles:

  • Blocking sound frequencies
  • Absorbing the sound
  • Isolating vibrations
  • Reactive (noise cancelling frequencies)

Our sound packages are technically engineered to maintain or increase airflow whilst achieving the desired regulatory noise requirements. With our extensive experience in the mining and mineral processing industries, MINETEK continues to design highly effective sound attenuation packages that facilitate access for operators and maintenance personnel while addressing restrictions on individual noise levels to ensure compliance. Sound attenuation packages also include independent certified noise data for all machines that are that have certified MINETEK sound packages installed.

Our experience and innovative technology help us identify significant noise sources and measure the exposure levels. Reducing noise levels on machinery provides the most effective way of protecting workers' hearing and improving operating conditions. MINETEK's modular acoustic packages are designed for most types of mining equipment and are easy to be installed worldwide because of their mobility. We maintain offices across the world so that our experienced team can easily travel to your company's site for certification and installation of our sound attenuation packages.

I have used these evaporators very successfully at mine sites where I have worked in the past. They are an extremely reliable unit and worked above expectations in the environment where we had them set up. As for spray drift/mist this can be controlled by the weather monitoring systems that are available with the units. Additionally, how you set them up and the amount of fall you can achieve allows for more moisture to be stripped from the droplets]will greatly benefit your overall evaporation rates.

The relatively small fans allowed us to utilise our existing bulkhead, where we were severely limited by space, which allowed us to use our existing infrastructure and dramatically reduce downtime in the mine during the change out. The installation was completed safely... and allows us to scale our ventilation flow with their pressure on demand system to suit our production profile.
