Our silica sand guarantees the accurate particle size distribution to let our clients get high foundry quality and refractoriness.
Detailed introduction to FOUNDRY silica sand:
Silica sand
Descriptions:
Silica sands contain a high proportion of silica which is produced form both loosely consolidated sand deposits and by crushing weakly cemented sandstones. Our silica sand includes a high silica content in the form of quartz and more importantly, very low levels of deleterious impurities, typically have a narrow grain-size distribution (generally in the range0.5 to 0.1mm)
Applications:
Silica sand could be used for glass, crystal,foundry, painting, oil and gas ,Stamped concrete ,water filtration ,gulf Course, water treatment, plastering etc.
