Quartz sand production line
The plant selects the appropriate quartz as raw material, processes it through a series of production lines, and refines it through a series of processes, resulting in high-purity quartz sand. The entire production line can be customized to meet customer needs, producing 5,000-70,000 tons of quartz sand.
Here’s a concise answer to your question:
What is quartz sand?
Quartz sand, also commonly known as silica sand, is a granular material composed primarily of silicon dioxide (SiO₂). Its primary mineral form is quartz, which is abundant, chemically stable, and hard (with a Mohs hardness of 7).
Key Characteristics:
High Purity: Quartz sand must contain at least 95% SiO₂ and must not contain iron.
Widely Used Industrial Mineral: Its chemical inertness, high melting point (approximately 1700°C), and hardness make it an essential material in industries such as glassmaking, casting, water filtration, construction, and sports fields.
Typical Uses:
Glass Production: A primary raw material in the manufacture of windows, bottles, fiberglass, and specialty glass.
Foundry: Due to its stability and high melting point, it is used as a mold and core material.
Water Filtration: Due to its uniform particle size, durability, and chemical resistance, it is used as a filter medium.
Construction: Enhances the durability and structural integrity of mortar, concrete, and asphalt.
Sports and Recreation: Commonly used on golf courses, sports fields, and playgrounds due to its drainage and consistency.
Characteristics
Composition: Primarily silicon dioxide (SiO₂), quartz mineral
Purity ≥ 95% SiO₂; low iron content
Hardness: Mohs hardness 7 – suitable for abrasives
Stability: Chemically inert, high melting point
Applications: Glass, foundry, filtration, construction, sports
Quartz sand is a versatile material—its durability, purity, and stability make it essential for many industrial processes and everyday applications, such as glass production, foundry, water filtration, and construction.
The quartz sand processing plant is an integrated operation focused on improving the purity and consistent size of industrial quartz sand. We select the appropriate quartz as raw material, process it through a series of production lines, and then refine and purify it to produce high-purity quartz sand. The entire production line can be customized to meet customer needs, producing 5,000-70,000 tons of quartz sand.
The high-purity silica sand produced by the quartz sand processing plant is suitable for industries such as glass manufacturing, foundry, building materials, and electronics.
Using specialized processing technology, the plant rigorously removes impurities, ensuring that the final product contains extremely low levels of impurities such as iron, feldspar, mica, and clay, meeting industrial-grade standards.
The quartz sand production line can be customized to meet various needs, from ultra-pure sand for semiconductor-grade glass to coarse sand for construction and foundry applications.
The advanced plant focuses on efficiency and environmental compliance, using various devices such as dust bags to reduce pollution and achieve a more environmentally friendly production method.
Quartz Sand Production Process
Calcination & Quenching: The ore is heated to high temperature, then rapidly cooled, causing thermal shock that cracks the quartz internally and exposes impurities for easier removal.
Crushing & Grinding: The thermally shocked quartz is then crushed and ground to sand-sized particles, liberating the quartz from attached impurities.
Screening & Desliming: The material is screened and washed to remove fine clay “slimes,” yielding a clean, uniform particle size for further processing.
Magnetic Separation: High-gradient magnetic separators remove iron and other magnetic impurities.
Flotation: Special reagents are added to separate remaining non-quartz minerals for removal; multiple flotation stages ensure maximum purification.
Acid Leaching: The quartz sand is soaked in acid solutions to dissolve away any remaining metallic impurities, while leaving the silica intact.
High-Temperature Chlorination: Finally, the sand is exposed to chlorine gas at high heat, vaporizing any trace elements and eliminating internal inclusions.
Outcome: The end result is ultra-high purity quartz sand (over 99.999% SiO2) with minimal impurities and a controlled particle size distribution, ready for high-end applications.
Tip: Different application scenarios (glass, construction, casting) have different requirements for fineness/impurity content, so the process needs to be slightly adjusted.
Main Equipment List for Quartz sand processing plant
A quartz sand production line is designed to transform raw quartz stone into high-quality silica sand through a series of controlled steps. Each stage has a dedicated machine to ensure efficiency, precision, and consistency in the final product.
1. Crushing
- Jaw Crusher (Primary Crushing): Handles large quartz blocks and reduces them into manageable sizes.
- Cone Crusher or Impact Crusher (Secondary Crushing): Further reduces material to finer particles, preparing it for classification.
2. Screening
- Multi-layer Vibrating Screen: Separates crushed quartz into different grain sizes, ensuring uniformity and removing oversized material.
3. Washing
- Wheel Sand Washer / Spiral Sand Washer: Removes clay, dust, and impurities, improving sand purity.
- Optional: Attrition Scrubber: For high-purity applications, this additional unit eliminates surface impurities and coatings.
4. Drying
- Rotary Dryer: Reduces moisture content, prevents clumping, and prepares sand for final processing or storage.
5. Magnetic Separation
- High-intensity Magnetic Separator: Removes iron and other magnetic contaminants, critical for producing high-purity quartz sand.
6. Final Packing
- Automatic Packing Machine: Weighs and packs finished quartz sand into bags or bulk containers for easy handling, storage, and delivery.
