Industrial Silica Sand

Industrial silica sand refers to sand having the composition and grain‐size distribution required for industrial applications. Specifically, industrial silica sand consists of well‐rounded, sand composed of almost pure quartz grains. Quartz, or silicon dioxide, is one of the most common minerals found on the Earth’s surface and is found in rocks like granite, gneiss, and sandstone. Industrial silica sand is a higher value product than sand and gravel used in the construction industry.

Industrial silica sand typically are mined from open pits of naturally occurring quartz-rich sand and sandstone. The material will be first crushed. Depending on the degree of cementation, several stages of crushing may be required to produce the desired size reduction. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing.

After crushing, the size of the material is further reduced to *0 mm or smaller by grinding, using ball mills, raymond mill, hammer mills, trapezium mill or ultrafine mills. The ground material then is classified by wet screening, dry screening, or air classification.
