The quartz sand filter of quartz sand separator



The sand 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, 7 hardness, brittle no cleavage, conchoidal fracture, oily luster, density 2.65, bulk density (1-20 mesh is 1.6 ~ 1.8), 20-200 mesh is 1.5, the chemical, thermal and mechanical properties has obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 ℃. Quartz sand is colorless and transparent quartz varieties, the greeks called "Krystallos", means "white", they are sure quartz is durable and solid ice. Ancient Chinese thought cold crystal on the mouth be able to quench it. Quartz sandstone is consolidation of clastic rocks, quartz particles content above 95%, and is derived from a variety of magmatic rocks, sedimentary rocks and metamorphic rocks, heavy minerals is less, associated minerals as feldspar, mica and clay minerals content. Quartzite sedimentary origin and metamorphism, the boundaries of the former clastic particles and cement is not obvious, which is a deep metamorphic grade, quality, and the pure quartz ore. Vein quartz is formed by hydrothermal process, almost all is composed of quartz, dense block structure. Quartz sand mineral content change is bigger, give priority to with quartz, followed by feldspar, mica, cuttings, heavy mineral, clay minerals content, etc.

Quartz sand color machine manufacturers from across the country, the quartz is more extensive. Quartz sand is using natural quartz ore, quartz writing process, from mining through crushing, screening, washing process, etc. Prismatic, globular appearance, pure white, has high mechanical strength, sewage capability is strong, good acid resistance performance. General fineness of products within the 120 mesh according to quartz sand. More than 120 mesh products called quartz powder. JiNing high-quality mines are mainly distributed in Inner Mongolia autonomous region, anhui fengyang, huanggang, hubei province, hebei lingshou high yield large quality, also have a small amount of distribution in guangdong and jiangxi.
