Efficient · Eco-Friendly · Intelligent
A New Generation of High-Quality Silica Sand Processing System

Rising Value of Silica Sand Calls for Professional Processing Equipment

Silica sand (also known as quartz sand) plays an increasingly vital role in high-value industries such as glass, ceramics, casting, photovoltaics, electronics, and chemicals. With stricter standards on particle shape, purity, and gradation, the demand for specialized processing solutions is rising.

Leveraging years of expertise in mining machinery, SBMX has developed a complete silica sand processing line tailored for deep processing, delivering intelligent, efficient, and environmentally friendly solutions.

Process Flow | Smooth, Efficient, and Precisely Controlled

  1. Vibrating Feeder
    High-efficiency feeders deliver raw ore evenly to jaw crushers, avoiding blockages and uneven loading.
  2. Primary & Secondary Crushing
    Heavy-duty and fine jaw crushers ensure precise particle size control and maintain optimal grain shape.
  3. Vertical Shaft Impact Crushing (VSI)
    Using a “rock-on-rock + vortex chamber” principle, the SBMX VSI sand maker achieves excellent sand shape with a forming rate of 40%–50%.
  4. Multi-Stage Screening
    High-frequency circular screens remove non-conforming particles and work seamlessly with return systems for reprocessing.
  5. Water Washing & Desliming
    Wheel or spiral sand washers effectively remove silt and fine impurities, meeting photovoltaic-grade purity standards.
  6. Dust Collection & Environmental Control
    Pulse dust collectors and automated spray systems are deployed across the line to ensure clean, dust-free production.
  7. Iron Removal
    High-gradient magnetic separators eliminate magnetic impurities such as iron oxides to enhance purity.
  8. Heavy Metal Removal
    Chelation, acid leaching, or flotation systems remove heavy metals like lead, zinc, and copper as needed.
  9. Drying
    Three-cylinder or rotary dryers quickly remove moisture, making the sand suitable for packaging or further processing.
