How to solve the problem of noise pollution in sand and gravel production line

In the sand and gravel production line, because they are all stone crushing equipment, it is easy to generate noise pollution. Among them, crushers, sand making machines, screening machines, etc. are the main sources of noise pollution. Noise pollution brings many problems to the production of the majority of users. Comprehensive improvement is required.

1, Reasonable choice of terrain
Noise pollution can only be called noise pollution when it has been contaminated within a certain range. Therefore, when choosing the terrain of the sand and gravel production line, attention should be paid to staying away from densely populated areas, especially in the design and planning, to use the *ography of mountains, hills, forests and so on. and other natural environment, and prevent noise transmission according to local conditions.

2, Sound insulation treatment
Using the principle of sound transmission, it is especially necessary to block noise through targeted sound insulation measures. Baffles are an efficient method of reducing noise through medium transmission. The sound insulation board should be made of high density material. To reduce noise, sound propagation is controlled by reflection and blocking. Starting from the actual location of the noise source of the sand and gravel production line, construction companies need to set up sound insulation sheds in relevant areas, and use sound insulation boards to seal the roof and walls.

3, Parts inspection method
Some sounds can be avoided or reduced at the source. For example, in the operation of major equipment such as crushers and screening machines, loose parts may cause additional vibration, which is one of the main noise sources. Therefore, the staff should fasten all parts well before operation; choose rubber springs instead of the vibration springs of the screening machine; traditional punched steel sieves and steel plates are replaced by rubber sieves or polyurethane sieves with low impact noise.

4, Special material processing
The screening machine is an area with serious noise, which has a lot to do with its physical properties.
The screening machine is composed of steel parts such as beams, screen surfaces, side plates, and reinforcing plates. These steel parts will vibrate during the working process, which will bring noise pollution. Due to the complexity of the screening equipment, the noise also has the characteristics of high sound level and high sound source.

The damping spring and damping rubber can be set between the screen boxes of the screening machine. As a material that converts mechanical vibration into thermal energy, damping material also plays a good role in noise reduction. At the same time, the sound absorber can be suspended in the air of the soundproof booth. The sound-absorbing function of the sound-absorbing material can absorb the sound reflected in the sound insulation booth, further reducing noise pollution.
