High-Frequency Sizing Screen
High-frequency fine sizing screen engineered for sharp fine particle separation (75µm to 3.0mm), dry/wet quartz sand grading, and multi-fraction mineral classification under high G-force excitation.
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 is the finest cut size achievable on the High-Frequency Sizing Screen?
It delivers sharp fine size cuts down to 75 microns (200 mesh) for both dry quartz sand and wet mineral slurries.
Q·02 How does independent deck drive technology benefit multi-deck screening?
Separate vibrators per deck allow operators to run higher frequencies on fine bottom decks and higher amplitudes on coarse top decks for maximum total efficiency.
Q·03 Is dust enclosure available for dry silica sand grading?
Yes, full sealed dust hoods with flexible suction ports connect directly to baghouse dust collectors for 100% dust-free plant operation.
Q·04 How fast can modular polyurethane screen panels be replaced?
Pin-and-wedge polyurethane panel systems allow complete single-deck panel replacement in under 30 minutes without special tools.
