Noise and Dust Control in Crushing and Screening Plants

Crushing and screening plants are essential in the mining and construction industries, but they generate significant noise and dust, which can have adverse effects on both the environment and human health. Effective control measures are necessary to mitigate these impacts.

Noise Control:

  1. Enclosure of Equipment: Enclosing crushers, screens, and conveyors can significantly reduce noise levels. Acoustic enclosures are designed to absorb and block sound waves.

  2. Use of Silencers: Installing silencers on engines and exhaust systems can help reduce noise emissions.

  3. Regular Maintenance: Ensuring that all equipment is well-maintained can prevent excessive noise caused by mechanical wear and tear.

  4. Noise Barriers: Erecting barriers around the plant can help contain noise within the site.

  5. Operator Cabins: Providing soundproof cabins for operators can protect them from high noise levels.

Dust Control:

  1. Water Spray Systems: Installing water spray systems at dust generation points, such as crushers and transfer points, can effectively suppress dust.

  2. Dust Collectors: Using bag filters or cyclone dust collectors can capture dust particles before they are released into the air.

  3. Enclosure and Ventilation: Enclosing dust-generating processes and using proper ventilation systems can help control dust dispersion.

  4. Regular Cleaning: Keeping the plant area clean and free of accumulated dust can prevent secondary dust generation.

  5. Use of Dust Suppressants: Applying chemical dust suppressants on roads and stockpiles can reduce dust emissions.
