1. Quartz Mining Equipment:Bulldozers, excavators, and other heavy machinery are used for extracting quartz from mines.
2. Crushing Equipment:Jaw crushers, cone crushers, or impact crushers may be used to break down the quartz into smaller pieces.
3. Grinding Equipment:Ball mills, Raymond mills, or other grinding mills can be employed to grind the quartz particles to the desired size. This step is crucial for obtaining fine quartz powder.
4. Classifying Equipment:Classifiers or sieves are used to separate the ground quartz powder into different size fractions. This helps achieve the desired particle size distribution.
5. Purification Equipment:Depending on the application, purification equipment such as magnetic separators or flotation cells may be used to remove impurities and enhance the purity of the quartz powder.
6. Drying Equipment:Rotary dryers or other drying equipment may be used to remove moisture from the quartz powder.
7. Packaging Equipment:After processing, quartz powder is typically packaged using equipment such as bagging machines or bulk loading systems.

What is silica sand?

Silica Minerals represent the group of minerals being composed of silicon and oxygen forming the chemical formula SiO2. Silica can occur in macrocrystalline, crytocrystaline and amorphous form.

Industry predominantly uses the crystalline form of silica, i.e. quartz. Silica is used as granular products containing the particle size range >63 µm. Fine grained silica is used as functional fillers in various applications.

Silicadioxide appears in almost 10 different crystal forms, with quartz, the most abundant representative, crystallizing in the trigonal crystal system.

Quartz is mined from hard rock deposits with the most important representatives being vein deposits or pegmatitic deposits and alluvial deposits. The mineralisation respectively the deposit type, the accessory minerals, impurities occurring together with the quartz in the deposit as well as the intergrowth of the minerals in the ore matrix define the process route.   

It is chemically inert, chemically resistant to almost all acids with the exception of hydroflouric acid and soluble in alkaline fluxes.

What is silica sand used for?

Silica sand is used in paints & plastics, abrasives, ceramics, glass, filtration, surface treatment in sports & leisure facilities, construction, in sealants & adhesives, chemicals production, in foundries, in oil production, metallurgical applications and agriculture.
