Treatment strategy for sandstone production line noise

The gravel production line usually consists of a plurality of equipment such as feeder, crushing and sand making equipment, belt conveyor, screening machine and centralized electric control. Different equipments will generate a lot of pollution during operation, including noise pollution, dust pollution and wastewater pollution. Properly handling these pollutions is an inevitable requirement of modern construction.

一、the noise processing method
In the sandstone production line, many equipments are prone to noise pollution. Among them, crushers and screens are the most serious areas of noise pollution, which have brought many problems to the production of users, and comprehensive management methods are needed.
1. Reasonable choice of terrain
Sound can only be called noise pollution when it brings problems to people’s production and life. Therefore, in the topographic selection of sand and gravel production lines, it is necessary to pay attention to areas that are far away from crowds, especially in design planning, it is necessary to make full use of the terrain. Land features, such as hillsides, hills, woods and other natural environments, block the way of noise transmission according to local conditions.

2. Accessories inspection method
Some sounds can be avoided or greatly reduced from the source. For example, in the main equipment work such as crushers and screens, the looseness of any component level may cause additional vibration.
In this regard, the operator must tighten all the components before the equipment is running; use rubber springs instead of the vibration springs of the screening machine; replace the traditional sieve plates and screens with rubber screens with low impact noise; Apply a proper amount of grease to the parts to reduce the frictional resistance of the equipment relative to the moving parts and reduce the noise caused by friction.
