Silica Sand Washing Plant
Heavy-duty silica sand washing & purification plant engineered for ultra-high purity (up to 99.5%+ SiO₂), low water consumption (up to 90% recirculation), and continuous operation in glass, solar, and foundry applications.
Engineered for producers selling on purity — stripping surface contaminants so your sand meets strict lab report thresholds.
Raw silica feed carries iron oxide coatings, clay films, and organic contamination that gravity washing alone leaves behind. This plant integrates mechanical attrition scrubbing ahead of classification specifically to scour surface contamination, ensuring your final output consistently meets the tighter SiO₂ and Fe₂O₃ spec limits demanded by glass, foundry, and ceramic buyers.
DISCUSS YOUR PROJECT99.4%+ SiO₂ Purity
Mechanical scrubbing strips iron-oxide and clay films gravity washing misses.
Tight Spec Control
Hydrocyclone classification maintains exact gradation bands on every batch.
<8% Moisture Output
Dewatering stage reduces stockpile moisture, cutting transport weight and drying fuel.

GOT QUESTIONS? WE HAVE ANSWERS.
Q·01 What silica purity and iron oxide (Fe₂O₃) thresholds can this plant achieve?
The plant reliably achieves up to 99.5%+ SiO₂ purity with residual Fe₂O₃ levels below 0.02%, fully satisfying the stringent requirements of photovoltaic solar glass and high-grade container glass manufacturers.
Q·02 Why is high pulp density (55-65% solids) critical in the attrition scrubbing stage?
High slurry density maximizes particle-on-particle friction under high-shear contra-rotating agitation, effectively scouring iron oxide stains without crushing quartz grains.
Q·03 How does the plant recover and recycle process water?
An integrated high-rate thickener clarifier combined with an automatic chamber filter press reclaims up to 90% of process water for continuous closed-loop reuse.
Q·04 What is the typical field erection and commissioning timeframe?
Pre-tested modular skid frames enable rapid structural assembly, piping connection, and electrical commissioning within 45 days.
