Sand and gravel production line environmental protection and finished product quality are equally important
Environmental protection requirements are becoming more and more stringent during construction. Sand and gravel production line manufacturers must not only ensure the quality of finished products. But also must ensure that the environmental protection standards in the production process are qualified for production. Therefore, the environmental protection of sand and gravel production lines is equally important as the quality of finished products, and must be done well.
The main pollutant during the operation of the gravel production line is dust. It is the key to establish an effective dust removal system. At present, it is widely used, and the dust removal effect is better. The dust removal system is mainly composed of water spray dust removal and bag dust removal. The function of water spray is to reduce dust generation. The function of bag dust collector is to collect the generated dust. In the aggregate production line, water spray devices are generally installed in the unloading bin and the funnel at the head of the tape machine at each transfer station. If steel structure greenhouses are used for finished product storage, water spray devices are also installed.
The design points of the water spray device are:
the position and quantity of the nozzles are designed reasonably. The water volume can be adjusted, and the water pressure is guaranteed. Otherwise, the dust suppression effect is not obvious and the mesh holes of the vibrating screen are easily blocked to affect production.
The design points of bag dust collectors are:
The specifications, quantity and final air ducts of bag dust collectors should be designed reasonably. And the collected dust should be stored in a separate warehouse and not returned to the production line to avoid secondary dust generation downstream.
In addition, trying to reduce the drop of each feeding chute in the design not only reduces a certain construction cost. But also is a means to reduce dust generation.
The system flow of the sand and gravel production line should be determined according to the specific environment, material characteristics, product particle shape and market demand. In terms of product particle shape, the cone crusher is better than the impact crusher, and the impact crusher is better than the hammer crusher. The finished product Compared with steel structure greenhouses. The use of closed steel warehouses (or concrete warehouses) for storage is more environmentally friendly. It is preferred in areas with stricter environmental protection requirements.
In recent years, environmental protection has become more and more stringent. Which has increased the production cost of sand and gravel manufacturers, but the results have been remarkable. The number of smoggy days has decreased, and the blue sky and white clouds have increased. Sand and gravel manufacturers should also change their minds and adapt to the situation. They should see that the government has changed from previous encouragement to mandatory implementation of environmental protection construction and environmental protection production. Most of the enterprises that do not meet the requirements or produce serious pollution have shut down or ordered A shutdown self-inspection is required. Therefore, factories and enterprises, including sand and gravel production lines. Should take advantage of this opportunity to complete their transformation and consider long-term considerations to achieve a sustainable industrial operation model.
