01 / Raw-material sorting
Color Sorting Line
Remove unwanted particles before purification.A belt-type colour sorter uses dual-spectrum optical recognition to detect and reject feldspar, mica, iron-bearing inclusions and discoloured particles. Steady conveying and high-speed air ejection help control ore quality before purification.
- Catalogue model
- SXJ-4
- Nominal throughput
- 10 t/h
- Feed particle size
- 3-100 mm
02 / Particle formation
Quartz Crushing & Sizing Line
Prepare the particle size required for purification.The line sizes crushed quartz ore for purification. Particle size affects flotation and acid-leaching efficiency, overall yield and the final product distribution.
- Catalogue series
- ZSX-10 to ZSX-100
- Processing range
- 10-100 t/day
- Product particle size
- Configured to your specification
03 / Magnetic removal & sizing
Magnetic Separation & Screening System
Remove iron impurities and separate particle sizes.This system removes weakly magnetic iron-bearing impurities and separates particles by size. The high-gradient magnetic field can be adjusted to suit the feed material and target product.
- Catalogue model
- CXSF-1
- Processing range
- 0.2-1 t
- Magnetic system
- Adjustable high-gradient field
04 / Physical purification
Flotation System
Selective separation of mica, feldspar and associated minerals.Flotation uses controlled bubble separation to remove mica, feldspar and other gangue minerals from quartz sand. The mineral composition, particle-size range and separation target determine the equipment and operating conditions.

- Operating temperature
- Ambient to 80°C
- Nominal batch size
- 0.5-1 t
05 / Chemical purification
Quartz Sand Acid-Leaching Line
Acid leaching, washing and recovery in one line.Strong-acid leaching with agitation removes metal-oxide impurities from particle surfaces and crystal fissures. Feeding, reaction, agitation, acid discharge, washing and acid recovery can be combined in a continuous closed-loop process.

- 10-50 t/tank
- Acid recovery
- At least 95%
06 / Controlled drying
Tower Drying Line
Consistent drying with controlled heat transfer and residence time.Counter-current hot-air exchange and variable-frequency discharge control the residence time of washed quartz sand. Indirect heat exchange reduces contact contamination, while PID temperature control and dust collection help maintain consistent dryness.

- TSHG-2
- Nominal throughput
- 2 t/h
- Working temperature
- 230-240°C
07 / High-temperature purification
Integrated Calcination & Chlorination Furnace
