Top 5 Noise Reduction Technologies for Sand Making Machine

1. Acoustic Enclosures & Soundproofing Panels

How It Works

Acoustic enclosures are sound-absorbing barriers made of multi-layered composite materials, such as:

  • Mineral wool (for high-frequency noise absorption)
  • Damped steel panels (for low-frequency vibration reduction)
  • Perforated metal sheets (to diffuse sound waves)

These enclosures are designed to fully or partially encase the crusher, reducing noise.

  • Engine roar (electric motors operate at <75 dB)
  • Exhaust fan noise (no need for cooling systems)

Some models use battery buffers to reduce peak power demand noise.

L?i ¨ªch

  • ? Noise levels drop to 70¨C75 dB (similar to a vacuum cleaner)
  • ? Zero exhaust emissions (better for indoor/urban use)
  • ? Lower operating costs (no fuel consumption)

For most operators, a combination of enclosures, vibration control, and rotor upgrades offers the best cost-to-benefit ratio. Meanwhile, ANC and electric crushers are ideal for urban quarries and zero-noise-policy zones.
