Silica sand is a natural mineral composed primarily of silicon dioxide (SiO₂). It is derived from quartz crystals and is widely used in industries such as glass manufacturing, foundry, ceramics, construction, electronics, chemicals, and water filtration.
Properties of Silica Sand:
- High Silica Content: Contains 95-99% SiO₂.
- Hardness: Rated 7 on the Mohs hardness scale, making it highly durable.
- Chemical Resistance: Resistant to acids and weathering.
- Heat Resistance: Can withstand high temperatures, making it ideal for refractory materials.
Applications of Silica Sand:
- Glass production (window glass, bottles, optical glass)
- Concrete and building materials (mortar additive, filler material)
- Ceramic and porcelain manufacturing
- Metal casting mold materials
- Electronics and semiconductors
- Water filtration systems
A silica sand crushing and screening plant is an industrial facility that processes raw silica-containing rocks through crushing, screening, washing, and drying.
The purpose of this plant is to convert raw silica sand into high-quality material suitable for industrial applications.
These plants refine raw silica sand to match specific size and purity requirements for various industries.
Functions of the plant include:
- Crushing large silica rocks
- Screening sand into different grain sizes
- Washing to remove clay and impurities
- Drying to reduce moisture content
- Storage and packaging
The processing steps include:
1. Feeding Raw Material
Silica-containing rocks are fed into the plant through bunkers.
2. Crushing Process
Large rocks are crushed using jaw crushers, impact crushers, or cone crushers.
3. Screening Process
The crushed material is separated into different grain sizes using vibrating screens.
4. Washing & Cleaning
Silica sand is washed to remove mud, clay, and organic impurities.
5. Drying Process
Wet sand is dried in industrial drying furnaces.
6. Storage & Packaging
The processed silica sand is stored and packed for shipment.
