With black spots to do in quartz sand, quartz sand color separator to help you
Quartz sand inside such flaws, if contain yellow dot, black spots in the sales price on the market than product compared with good selling price may be lower quartz sand. At present all over the country demand for there are quartz sand color to choose. Ann beauty of quartz sand color separator for now for quartz sand color choose mainly for the yellow dot, black spots to choose don't choose other range in 2-40 mesh, the scope of effect is very good, less than 40 mesh better words caused by quartz sand is too small material waste is serious. Quartz sand is the quartz writing processing of quartz grain, quartz is a kind of non-metallic minerals, is a hard, wear-resisting, stable chemical properties of silicate minerals, the main mineral composition is SiO2, quartz sand color for the milky white or colorless translucent, mohs hardness 7, quartz sand is important industrial mineral raw materials, the hazardous chemicals, widely used in glass, foundry, ceramic and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive, filter material and other industries.
Silica sand, also known as silica or quartz sand. Is the quartz as the main mineral composition, particle size in the refractory particles 0.020 mm to 0.020 mm, according to the mining and processing method is divided into artificial silica sand and sand washing, sand washing, selection of natural silica sand such as sand (flotation). Silica sand is a hard, wear-resisting, stable chemical properties of silicate minerals, the main mineral composition is SiO2, the color of the silica sand for the milky white or colorless translucent, 7 hardness, brittle no cleavage, conchoidal fracture, oily luster, relative density 2.65, chemical, thermal and mechanical properties has obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 ℃. Color white, weak yellow, brown and gray, silica sand has higher fireproof performance. Silica sand is an important industrial mineral raw material, widely used in glass, foundry, ceramic and refractory materials, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.
