Silica, chemically known as Silicon Dioxide (SiO₂), is the fundamental component of quartz. Through millennia of natural weathering by wind and water, quartz breaks down into the granular material we recognize as silica sand. High-purity silica sand exhibits a milky white appearance, while increased impurity levels result in brown or light brown hues. With a formidable melting point near 1750°C, silica sand particles typically range from 0.02mm to 3.35mm, occasionally larger.
This versatile mineral is indispensable across diverse sectors: glass manufacturing, foundry metal casting, chemical production, construction materials, paints & coatings, ceramics & refractories, oil & gas recovery (frac sand), and numerous others. Significant silica sand deposits are found globally, including Algeria, India, Bangladesh, Indonesia, the Philippines, Singapore, Egypt, and Brazil.
Given its critical role – especially in flat glass production where purity is paramount – silica sand suppliers must deliver consistently high-quality, impurity-free product. Achieving this demands sophisticated sieving and grading solutions.
Raw silica sand ore contains undesirable components: sticky clay, various impurity minerals, and magnetic particles. Initial washing removes some contaminants, but precision separation requires advanced technology. This is where Sanyuantang's expertise becomes essential. While sieving sand may seem straightforward, achieving high throughput, precise particle size distribution, operational efficiency, and sustained reliability necessitates specialized equipment and process knowledge.
Primary Oversize Removal with Sanyuantang Vibro Separators:
The raw, washed sand first encounters our high-capacity Vibro Separators.
These robust machines efficiently remove oversized waste particles and contaminants exceeding the target size fraction.
This critical step protects downstream equipment and ensures only correctly sized material proceeds.
Residual magnetic minerals (like iron particles, ilmenite, hematite) are removed using specialized Magnetic Separators.
Precision Matters: Effective removal requires specific magnetic intensities. Iron typically demands ~1000 Gauss, while ilmenite/hematite necessitate powerful 8000-9000 Gauss fields.
Different end-use specifications dictate the required level of mineral impurity removal.
The purified sand now undergoes exact grading into specific size fractions tailored to its final application.
Sanyuantang's Vibro Sifters generate intense, controlled vibrations.
This action enables highly efficient stratification, rapid sieving, sharp particle separation, and exceptional throughput rates, delivering the precise gradation demanded by glassmakers, foundries, or frac sand producers.
Final Processing:
The accurately graded sand is then dried and packaged, ready for shipment to fulfill stringent industry requirements.
