실리카 모래 정제 과정은 무엇이며, 가공 공장에 어떤 장비가 필요한가요?
The silica sand purifying process involves the removal of impurities such as clay, iron oxides, and other minerals to obtain high-purity silica sand, which is widely used in industries like glassmaking, foundries, construction, and electronics. Below is an overview of the purifying process and the equipment needed for a silica sand processing plant:
Silica Sand Purifying Process
Crushing and Screening
- 목적: To break down larger silica sand particles into smaller sizes and separate unwanted large impurities.
- 과정
: Raw silica sand is fed into crushers (jaw crushers, cone crushers, or impact crushers) and then screened to the desired size.
Washing and Desliming
- 목적: To remove clay, silt, and other fine impurities.
- 과정
:
- Use a washing machine or scrubber to clean the silica sand.
- Desliming involves hydrocyclones or spiral classifiers to remove fine particles and slimes.
자기 분리
- 목적: To remove magnetic impurities like iron oxides (Fe₂O₃).
- 과정
: A magnetic separator is used to extract magnetic minerals, making the sand purer.
부유
- 목적: To remove non-magnetic impurities like feldspar and mica.
- 과정
: Chemicals are added to a flotation cell to separate silica sand particles from impurities based on their surface properties.
Acid Leaching
- 목적: To remove stubborn impurities like iron and aluminum oxides.
- 과정
: Silica sand is treated with acids (such as hydrochloric or sulfuric acid) to dissolve impurities.
탈수
- 목적: To remove excess moisture from the sand.
- 과정
: Use dewatering screens or hydrocyclones to reduce water content.
Drying and Sieving
- 목적: To dry the sand and achieve uniform particle size.
- 과정
: Use a rotary dryer and vibrating screens to achieve the desired moisture content and particle size.
Final Quality Control
- 목적: To ensure the silica sand meets purity and size specifications.
- 과정
: Use advanced equipment like X-ray fluorescence (XRF) analyzers to verify composition.

Considerations for a Silica Sand Processing Plant
- Raw Material Characteristics: Analyze the silica sand’s composition and particle size to determine the required purification steps.
- Capacity Requirements: Scale the plant based on production goals.
- Water and Energy Supply: Ensure adequate water and energy for washing, drying, and other processes.
- 환경 준수: Implement dust suppression, water recycling, and waste management systems to meet environmental standards.
By carefully selecting the right processes and equipment, a silica sand processing plant can produce high-purity silica sand suitable for various industrial applications.
