Quartz sand is a non-metallic minerals, is a hard, stable wear and chemical properties of silicate minerals, the main mineral component of SiO2, quartz sand color is white or colorless, translucent, hardness 7 quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasive and other industries.
Quartz sand has the unique physical and chemical properties, making it occupies a pivotal in aviation, aerospace, electronics, machinery, and the rapid development of today's IT industry position, especially its intrinsic molecular chain structure, crystal shape and lattice variation , it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties, in many high-tech products are playing an increasingly important role. Quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, high-purity quartz sand abrasives and other industrial.
The first stage
First, chunks of quartz by jaw crusher preliminary crushing
The second stage
Then produced into a coarse material transported by belt conveyor to the cone crusher (or crusher) for further crushing
The third stage
Recovery of coal and pyrite Method 1: simple process, which were selected by screening good coal and low-quality coal, but picked pyrite. Recovery of coal can be used for power boiler fuel, can be used for washing gangue materials, pyrite can be used for chemical raw materials.
The fourth stage
Quartz crushing failure by the system to continue, until the production of finished material
Quartz can manufacture glass, refractories, smelting ferrosilicon, metallurgical flux, ceramics, abrasive materials, casting, quartz stone use in the construction of its strong acid etching medium capacity, used for extracting acid and acid of concrete mortar . Silica as a core raw material silicon feedstock plays an irreplaceable role in the production and supply of basic raw material of silicon. It has the unique physical, chemical optical properties, making it plays an increasingly important role in many high-tech products, such as, IT industry's core technology products - computer chips, fiber optics, electronics industry resonator , the new electric light, high insulation sealing materials, aerospace equipment, military technology products, special optical glass, chemical analysis instruments, etc., are inseparable from these basic materials. Beautiful crystalline quartz and shape can be used for glasses and precious crafts using piezoelectric quartz crystal can be made without the wire industry frequency stabilizer, quartz filters. Can produce various lenses, reflectors, spectral tube, the optical waveguide and optical instruments prisms, polarizers and the like. Has been widely used to make artificial hydrothermal quartz crystal temperature difference method for the manufacture of the piezoelectric element. In the chemical industry, quartz can be used for acid temperature instruments and utensils; in the electrical industry, often using quartz as excellent insulating materials; quartz is an excellent glass, enamel and refractory brick manufacturing industry raw materials; melting quartz outstanding performance also it is widely used in metallurgy, food, pharmaceutical and paper industries. Export of quartz (sand) mostly used in metallurgy and refractory industries.
