Quartz sand with high insulation, corrosion resistance, wear resistance, high temperature resistant and unique optical effect, widely used in construction, chemical industry, machinery, electronics, rubber, coatings, smelting and aerospace and other high-tech projects, the high purity quartz sand is the production of monocrystalline silicon, polycrystalline silicon, quartz glass, optical fiber, solar cells, integration substrate material of raw materials, such as specification this shows how important strategic position of quartz sand, quartz sand production technology and production equipment is closely related to many high-tech industry development in our country.There are two kinds of process flow of quartz sand production line, one is dry separation of quartz sand production line.The other is the process flow of wet quartz sand production line: grinding - screening - washing sand - drying - screening - iron removal.
Today we will learn about the production process of wet refined quartz sand production line. The composition of refined quartz sand is: SiO2 99-99.5%, Fe2O3 0.02-0.015%. The particle size range is 5-480 mesh.The main equipment of wet refining quartz sand production line includes jaw crusher, impact crusher, quartz sand making machine, dryer, vibrating screen, sand washing machine, feeder, conveyor and so on.
Wet process refined quartz sand production line has the following characteristics: wet process refined quartz sand production line has a high degree of automation, energy saving and environmental protection, low operation cost, simple maintenance, can achieve large-scale production;This production line has solved the problem of unqualified sand grain size of traditional quartz sand production line. The finished product has uniform sand grain size, good grain size, reasonable gradation and completely conforms to China's sand and stone standards.The crushing equipment used in this production line is suitable for the production of rock with high hardness. Wearing parts are not easy to wear, which can significantly reduce the production cost.The production line can meet the different particle size requirements of sand aggregate by adjusting the equipment parameters, and users can produce marketable products according to the market conditions, so as to realize multi-purpose in the first line and reduce the investment in later production.
The following is a detailed explanation of the process flow of the production line for wet refining quartz sand:Stone stone by first for feeder into the jaw crusher for primary crushing, processing into a small stone, then into the counterattack crusher crusher, finely, due to some quartz sand products have more request for the size and the shape of particle size, so can be made from plastic sand, quartz sand stone machine size suitable quartz sand into the sand washer to clean and remove dirt, opaque, such as magazines, all into the tank after cleaning, use the dryer to the sand inside the tank completely drying into dry sand, using magnetic separation equipment in the process of vibrating sieve screening quartz sand to remove iron, the finished products into finished product storehouse, complete the whole process.
In recent years, China attaches great importance to the research and development of refined quartz sand technology. The unique physical and chemical characteristics of quartz sand make IT occupy a pivotal position in aviation, aerospace, electronics, machinery and today's rapidly developing IT industry, and play an increasingly important role in many high-tech products.
