Our Production Process

A nine-stage, fully integrated processing route — from our own high-purity quartz mines to export-ready grit — engineered for consistent purity, whiteness and particle size.

  1. Primary crushing of quartz lumps 01

    Primary Crushing

    Quartz lumps are reduced to coarse chips.

  2. Secondary cone crusher refining quartz chips 02

    Secondary Crushing

    Chips are refined to a uniform feed size.

  3. Vibrating screens classifying quartz chips 03

    Screening & Classification

    Material is separated into working size fractions.

  4. Optical colour sorter removing coloured quartz 04

    Colour Sorting

    Optical sorters remove coloured and stained particles.

  5. Close view of white quartz grit 05

    Grit Formation

    Premium quartz grit with uniform particle shape.

  6. Multi-deck grading screens sizing quartz sand 06

    Precision Screening & Grading

    Multi-deck screens deliver accurate grading.

  7. Magnetic separation of quartz sand 07

    Magnetic Separation

    Ferrous contaminants are removed for low iron content.

  8. Final optical colour sorting of quartz sand 08

    Final Colour Sorting

    A second sorting pass secures superior whiteness.

  9. Laboratory testing of quartz sand samples 09

    Quality Assurance & Testing

    Every batch is tested for purity, size and whiteness.

  10. White jumbo bags of quartz sand ready for dispatch 10

    Packaging & Dispatch

    Packed in high-quality export-grade jumbo bags with liners attached.

High-purity quartz lumps at our own mine in Andhra Pradesh
Step 1

Procuring High-Purity Quartz Lumps

Only carefully selected high-purity quartz lumps are sourced from our own mines in Andhra Pradesh. Every lot is visually inspected before entering the production facility.

  • Own Mines
  • High SiO2
  • Consistent Raw Material
  • Reliable Supply
Primary and secondary crushing of quartz lumps
Step 2

Primary & Secondary Crushing

Large quartz lumps are reduced into uniform chips using advanced crushing equipment.

This stage prepares the material for efficient downstream processing while maintaining mineral integrity.

  • Advanced Crushers
  • Uniform Chips
Vibrating screens separating quartz chips by size
Step 3

Precision Screening

The crushed quartz is screened to remove oversized and undersized particles.

Only the desired chip sizes proceed to the next stage.

  • Multi-Deck Screens
  • Accurate Sizing
Optical colour sorter removing coloured quartz particles
Step 4

Optical Colour Sorting

High-resolution optical colour sorters remove coloured particles, stains and unwanted minerals.

Only premium white quartz chips continue further.

  • AI Vision
  • High Speed
  • High Accuracy
Controlled grinding of quartz chips in specialised mills
Step 5

Controlled Grinding

The selected quartz chips are ground using specialised milling systems to achieve the desired particle size.

The grinding process is continuously monitored for consistency.

  • Continuous Monitoring
  • Controlled Particle Size
Multi-stage screening of ground quartz through multiple mesh sizes
Step 6

Multi-Stage Screening

Ground material is screened through multiple mesh sizes to obtain highly accurate size distribution.

Available Sizes
  • 0.1 – 0.4 mm
  • 0.4 – 0.8 mm
  • 0.8 – 1.2 mm
  • 1 – 3 mm
  • 2 – 4 mm
  • Custom Sizes

Step 7

Grit Formation

The screened material is converted into premium industrial quartz grit with uniform particle shape and consistent grading.

  • Uniform Shape
  • Consistent Grading
Magnetic separator removing ferrous contaminants from quartz
Step 8

Magnetic Separation

Powerful magnetic separators remove ferrous contaminants to ensure exceptional purity.

  • Low Iron Content
  • Improved Product Quality
  • Better Industrial Performance
Final optical colour sorting of quartz before packing
Step 9

Final Optical Colour Sorting

Every batch undergoes a second round of colour sorting to eliminate the finest impurities.

This final inspection ensures superior whiteness and visual consistency before packaging.

  • Maximum Purity
  • Uniform Colour
  • Export Quality
Laboratory testing of quartz sand samples
Quality Assurance
