Necessity And Investment Prospect of Using Sand DryerNecessity and investment prospect of using sand dryer
When the sand is just picked up, it will contain a lot of water. If the supply can keep up with the sales, just a little drying can be done. If the sales volume is large, only natural drying is not enough. Drying and subdividing the sand through the sand dryer can effectively improve the output and make the sand sell more widely.
There are many kinds of sand: river sand, yellow sand, sea sand and so on. These sands are classified according to different particle sizes, and the use of sand is different with different particle sizes. The sand used in building thermal insulation materials is the same as that used in building houses, but they also need to be detailed. When the sand is wet, there is no way to classify it. At this time, we need to use the dryer to dry the sand and put it into the vibrating screen. After different mesh sizes of the screen, we can separate the sand from each other and store them separately. Different sands have different prices when they are sold.
Sand is divided into: Construction sand, dry sand, natural sand, sand 4-8 mesh, sand 10-20 mesh and so on. It is mainly used in concrete with strength greater than c30-c60 and hydraulic concrete with frost resistance or other requirements.
First of all, when the river sand is used in the thermal insulation material industry after drying, the moisture content should be controlled below 1%, because the thermal insulation material is generally the material with the guiding thermal coefficient less than or equal to 0.2. In one case, the development of thermal insulation materials is very fast, and the application of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. Every ton of mineral wool insulation products used in construction can save one ton of oil a year. The market demand of thermal insulation materials in China is gradually increasing, and the industry can drive the development of dryer industry faster and better. Some customers can consider engaging in dry powder mortar insulation material industry in the investment process.
Secondly, filling materials can be used after river sand is dried. The industry mainly needs filling materials for light industrial products. Generally, the demand is not too large. Customers can choose a small sand dryer for investment.
Finally, many local building materials industry is developing rapidly, sand drying can be used for building materials production, castable and abrasive construction.
