I. The difference between wet sand production and dry sand production 1, and the subsequent equipment configuration is different.
Wet sand making is a way used by sand washer, which can reduce the silt content of machine-made sand, and the sand particles are round in appearance and beautiful in quality. Dry sand production is a mode of using a powder separator, which can separate sand from powder, select high-quality sand particles that meet the requirements of building sand, and collect dust as a by-product.
2. Different application areas.
Wet sand production is suitable for areas with abundant water resources and close to water sources. In wet sand production, sedimentation tanks can also be established to realize the recycling of water resources. Dry sand production is not limited by environmental areas, and sand production can also be realized in areas where water resources are scarce.
3. Different investment costs
In the reproduction process of wet sand production, a lot of water is needed for cleaning, while in dry sand production, it is separated by a powder separator without using a lot of water.
Second, the advantages and disadvantages of wet sand Advantages of dry sand compared with wet sand:
1. There is no dust pollution in the production process of wet sand, which reduces air pollution.
2. The sand made by wet method has clean surface, round appearance and good impression.
Disadvantages of wet sand production:
1. A lot of water resources are needed in the production process of wet sand, and the cost is high.
2. Limited by the environmental area, the water resources in the area are not enough and cannot be used.
Advantages of dry sand production:
1. The use cost of water resources in the process of dry sand production is reduced, which is not limited by the regional environment.
2. The dry sand production line is compact in layout and occupies a small area.
Disadvantages of dry sand production:
1, dry production process contains a lot of dust, which is easy to cause air pollution.
2. Dry sand production requires high raw materials, and it is necessary to strictly control the content of impurities such as soil and organic matter in sand and gravel.
