The reason for steel structure sealing of concrete mixing pla

1.Prevent the dust of sand and gravel raw material
In the concrete mixing plant, the dust of the sand and gravel material is mainly related to the wind speed and the water content of dust particles. Therefore, reducing the air storage of sand and gravel and other materials and ensuring the certain moisture content (water content is greater than 10%) are effective means to curb this kind of dust. Sealing the raw material yard with steel structure can effectively reduce the dust. At the same time, in the steel structure plant, we can install a spray system device to regularly spray to make it atomization when loading and unloading, to keep the surface of the sand wet. These measures can control the dust in the sand and gravel yard in a certain distance range, which greatly reducing the impact of the external environment, to achieve the effective closure and control to the pollution source.

2.Prevent the dust in the transport process
In the concrete mixing plant, sealing the belt corridor, the transporting, measuring and feeding of sand and gravel raw material should be carried out in a closed environment, not only the anti dust effect is good, but also it also controls the spread of pollution sources and restrains the loss of raw materials.

3.Prevent the dust of breathing hole on the top of the powder tank
As for the dust of the breathing hole on the top of the powder tank, we can build a main building with steel structure to seal it. At the same time, using the traditional collection method of dust to install the filter dust collector on the breathing hole on the top of the various powder tanks. On the bottom of the powder tank, we can adopt the  negative pressure suction dust collecting device. The dust collection rate of this measure is more than 99.5%.
