1、 Equipment name: quartz sand

意昂体育2、 Specification and model: hdn-6 ~ 8 mesh

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product Description:

Quartz sand is a hard, wear-resistant and stable silicate mineral with stable chemical properties. The main mineral composition of quartz sand is SiO Ψ. The color of quartz sand is milky white or colorless and translucent. Its hardness is 7. It is brittle and cleavage free. It has shell like fracture and grease luster. The density is 2.65, and the packing density is 1.6-1.8 for 1-20 mesh and 1.5 for 20-200 mesh. Its chemical, thermal and mechanical properties are obviously different It is isotropic, insoluble in acid, slightly soluble in KOH solution, melting point 1750 ℃.

5、 The purification method was as follows
1. Scrubbing and desliming:

Scrubbing refers to the removal of thin-film iron, bonded and argillaceous impurity minerals on the surface of quartz sand and further grinding of mineral aggregates without monomer by means of mechanical force and abrasive stripping force between sand grains, and then the effect of further purification of quartz sand is achieved through grading operation. Nowadays, there are mainly rod friction and mechanical scrubbing (the scrubbing concentration is generally 50% - 60%). There are mainly mechanical scrubbing, rod grinding scrubbing, high-efficiency strong scrubbing and ultrasonic scrubbing.

意昂体育2. Magnetic separation:

意昂体育Magnetic separation is mainly used to remove magnetic minerals from quartz sand. How to remove weak magnetic minerals such as hematite, limonite, biotite and other weak magnetic minerals can be removed by strong magnetic machine, while strong magnetic minerals such as magnetite can be removed by weak magnetic separator.

3. Flotation:

Flotation is used to remove feldspar, mica and other impurities in quartz sand that cannot be removed by magnetic separation, so as to further improve its purity.

4. Acid leaching:

Acid leaching is to make use of the fact that quartz is insoluble in acid (except HF acid), and other impurities can be dissolved by acid solution, which can further purify quartz.

意昂体育5. Bioleaching:

意昂体育It refers to the use of microorganisms to leach thin-film iron or disseminated iron on the surface of quartz sand particles, which is a newly developed iron removal technology.

意昂体育Quartz sand is an important industrial mineral raw material, not a chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries

Glass:

意昂体育◇ the main raw materials of flat glass, float glass, glass products (glass tank, glass bottle, glass tube, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and anti-ray special glass, etc;

◇ Ceramic and refractory materials:

意昂体育raw materials and glazes of porcelain, raw materials of high silica brick, common silica brick and silicon carbide for kiln;

意昂体育◇ Metallurgy:

意昂体育raw materials or additives and fluxes of silicon metal, ferrosilicon alloy and silicon aluminum alloy;

◇ Building:

concrete, cementitious material, road building material, artificial marble, cement physical property test material (namely cement standard sand), etc;

意昂体育◇ Chemical industry: 

意昂体育raw materials of silicon compounds and water glass, filler of sulfuric acid tower, amorphous silica powder;

◇ Machine: 

意昂体育the main raw material of foundry sand, grinding materials (sand blasting, hard abrasive paper, sandpaper, abrasive cloth, etc.);

意昂体育◇ Electronic:

意昂体育high purity metal silicon, optical fiber for communication, etc;

◇ Rubber, plastic: 

意昂体育filler (can improve wear resistance);

◇ Coatings:

fillers (can improve the acid resistance of coatings).
7、 Filter features:

意昂体育◇ The quartz sand filter material layer is thick, the filter is deep, and the civil engineering cost is high.

意昂体育◇ High filtration efficiency, good filtering effect, no need to stop backwashing, low operating cost.

意昂体育◇ Due to the high head loss, it is generally necessary to set up the secondary lifting pump house, which increases the operation cost.

◇ The number of active sand filter can be increased or decreased according to the change of water quantity, which is mainly suitable for small-scale sewage treatment plants.
