With the development of new energy and computer technology, the market demand for silicon products increases; crystalline silicon is extracted from quartz sand, so artificial sand making machine processing is bound to become a hot industry.
Quartz sand is mainly made by quartzite; China is rich in quartzite, the explored reserve is about 32 billion tons. Quartz sand is a hard, wear-resistant silicate mineral with stable chemical property, the main mineral component SiO2 is up to 99%; quartz sand is characteristic by milky red or translucent colorless color, Mohs hardness 7 and sheen oil; the relative density is 2.65; its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid and slightly soluble in KOH solution with the melting point of 1750 ° C.
Quartz sand is an important industrial mineral raw material to manufacture glass, refractories, ferrosilicon, metallurgical flux and ceramics, abrasives material. Additionally, quartz sand is also used to make acid-proof concrete and acid-resistant mortar depending on its strong acidoresistance in building.As a core raw material of silicon feed stock, silica plays a foundational and irreplaceable role in the production and supply of silicon feedstock. Its unique physical, chemical, optical properties make it play an increasingly important role in technological products.
Quartz sand is generally first broken by multi-stage crushing and screening line which is composed of impact crusher or jaw crusher, and then ground into appropriate fineness by Raymond mill. Shanghai sbm provides customers with the professional jaw crusher, impact crusher and Raymond mill for quartz ore crushing and milling.
Shanghai sbm always adhere to the development philosophy of customer demand-oriented, make technology innovation as the impetus, constantly advance in the market test, and strives for the user to create the most appropriate quartz sand production line equipment.
