Guide
In recent years, with the limitation of natural sand mining and the scarcity of resources, artificial sand has gradually become the mainstream of the market. However, in the processing of stone materials, due to the intense collision and the stone material itself has a certain soil content, the artificial sand contains a certain amount of stone powder and mud powder, which in turn affects the gradation of artificial sand. In order to solve the problem of powdery, wet sand and dry sand have appeared.
Wet sand making and dry sand making
To put it simply, the sand washing machine is equipped with a sand washing machine, and the method of washing the powder is called wet sand making, which is more suitable for areas with heavy rain and abundant water resources in the south.
The method of separating the sand powder by using the classifier is called dry sand making, and is more suitable for places where water is scarce, and environmental protection requirements are not very high.
The similarities between the two
The main equipment used in the two production lines is the same, namely the coarse crushing machine, the fine crushing machine and the high efficiency sand making machine. The purpose of both is the same, both for the higher quality of the sand and in line with the standards for construction sand.
The difference between the two
1. Subsequent configuration devices are different
Wet sand making is a sand making mode that uses a sand washing machine to achieve roundness of sand and reduce soil content.
The dry sand making method adopts the mode of the powder sorting machine to achieve the separation of the sand powder, and finally selects the construction sand with excellent quality, and the dust is also collected as a by-product.
2, the applicable area is different
Wet sand making is suitable for use in watery areas, close to the water source. Wet sand making can establish a sedimentation tank to achieve the purpose of recycling water resources. At the same time, it can also be added to a fine sand recovery machine to collect fine sand and sand powder in wastewater.
Dry sand is suitable for use in areas far from the water source, such as the arid areas such as the north.
3. Different investment costs
The dry sand production line uses a high-efficiency classifier for sand powder separation. There is no need to add a large amount of water to clean the production process, and the overall production cost will be relatively low.
4, different development time
The dry sand making technology is later than the wet method and is further developed on the basis of the traditional wet sand production line. This technique is relative to wet sand making, which does not require water during the dust removal process of the sand, and is therefore referred to as a dry sand production line.
Advantages and disadvantages comparison
summary
In actual production, whether wet sand or dry sand is selected depends on the area and water resources, the cleanliness of raw materials, and the specific requirements for aggregate, artificial sand powder content and fineness modulus. Choose your own production situation.
Draw texturing yarn (DTY) which is made from Pre-Oriented yarn by the texturing forming process. The fiber is crimp, with high fleeciness and elasticity. The yarn fabric is soft, skin-friendly and soft-reflected in color.
Main production equipment Germany Barmag FK6-1000 and Japan TMT ATF-1500FOUR
