The silica sand color in raw material maybe white, yellow, brown,ect.Application Area of Silica Sand: Mobile Crusher is an important industrial mineral raw material, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, machinery, electronics, chemical, plastic, abrasive, rubber, aerospace and other industries.

The content of silica in ordinary silica sand is between 90% and 99%, the content of iron oxide is less than 0.02%, the content of silica in refined silica sand is between 99% and 99.5%, the content of iron oxide is less than 0.015%, the content of silica in high purity quartz sand is 99.5% to 99.9%, and the iron oxide content is less than 0.001%. The silica sand with high purity is milky white. When the impurity content is more, the silica sand will be brown and light brown.

The melting point of silicon sand is about 1750 C, the particle size is between 0.02mm and 3.35mm, and it is insoluble in acid except hydrofluoric acid. It has good chemical stability, electric edge, wear resistance and so on.Silica sand material Mainly Distribution in the world :

Silica sand ore is richful in world wide, such as Algeria, India, Bangladesh, Brazil, Egypt, Singapore, Indonesia, Philippines,ect.Silica Sand Regular Specifications:The regular specifications of silica sand are: 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80mesh, 100-120 mesh, 200 mesh, 325 mesh, SiO2 > 99-99.5% Fe2O3 less than 0.02-0.015%.The silica sand raw material is usually will contain sticky clay, Kaolin clay, ilmenite, Hematite, Iron, and other magnetic minerals.
