The mining and mineral processing industry, especially stone crushing and screening, not only faces dust and water pollution but also noise pollution – a serious but often overlooked problem. Continuous noise from jaw crusher, cone crusher, vibrating screen, conveyor belts not only affect the health of workers but also impact the surrounding environment.
So what is the noise level in the stone crushing and screening industry? Is it really dangerous? And what solutions can help businesses ensure production efficiency while minimizing the harmful effects of noise? Let's find out the details through this article.
1. Noise standards in stone crushing and screening industry
According to National Technical Regulations on Noise QCVN 26:2010/BTNMT, the maximum noise level is specified as follows:
| Area | From 6am – 9pm | From 9pm – 6am |
|---|---|---|
| Special areas (hospitals, schools, libraries, churches…) | 55 dB | 45 dB |
| Regular areas (residential areas, individual houses, offices, hotels…) | 70 dB | 55 dB |
🚨 Warning: Noise from stone crushers can exceed 85 - 100 dB, causing serious health effects if there are no reasonable protective measures.
2. Noise in the stone crushing and screening industry compared to other noise levels
According to the American Academy of Audiology, sounds are classified into different levels:
| Warning level | Noise level (dB) | Real life example |
|---|---|---|
| 🚨 Immediate danger | 140 dB | Fireworks, gunshots, car sounds (turn on at maximum volume) |
| ⚠️ Very loud, uncomfortable | 120 – 130 dB | Jackhammer, jet plane, ambulance siren |
| ⏳ May be harmful if listened to for more than 30 minutes | 100 – 110 dB | Rock crushers, concerts, major sporting events |
| ⚠️ Dangerous with long term exposure | 85 – 90 dB | Lawn mower, concrete mixer |
| ✅ Safe | 50 – 70 dB | Normal conversation, light traffic noise |
🚨 Note: Listening to sounds above 85 dB for long periods of time can cause permanent hearing loss.
3. Noise of Terex stone crusher
Noise in the stone crushing and screening industry, or in other words, the noise of the largest stone crushing station is determined at the jaw crusher location. Having to process large-sized, high-hardness materials, the jaw crusher creates loud sounds, requiring operators to have the knowledge to protect themselves and prevent the impact of the equipment on their hearing.
With other crushers: hydraulic cone crusher, VSI, ready, washing machine… of Terex lower noise
💡 Conclusion: Without noise reduction measures, workers exposed to long-term noise will suffer serious effects on their hearing and overall health.
4. Noise treatment solutions in the stone crushing and screening industry
4.1 For operators – Health protection is a top priority
🔹 Fully equipped with hearing protection (noise-canceling headphones, industry standard earplugs).
🔹 Limit working hours in high noise areas (regulate reasonable working shifts).
🔹 Raise awareness of the harmful effects of noise and preventive measures.
4.2 For equipment – Noise reduction solutions at the source
🔹 Using new generation crusher with noise reduction technology, optimizing transmission mechanism to limit vibration.
🔹 Soundproofing the crusher and vibrating screen with specialized sound-absorbing materials.
🔹 Lubricate and maintain regularly to reduce vibration and limit unnecessary noise.
4.3 For the working environment – Effective noise control
🔹 Installation grinding station in closed factory (prefabricated steel building) to absorb noise, avoid spreading to the surrounding environment.
🔹 Build soundproof walls around the production area to reduce the impact on the community.
🔹 Plant trees around the factory to absorb noise and reduce negative impacts.
📌 Reality: Some stone crushing plants in Lao Cai, Malaysia, and Thailand have applied the closed factory model, helping to reduce 30 – 40% noise compared to outdoor crushing plant.
