Quality Assurance
At MAXSTONE GLOBAL INDIA LLP, we are driven by a deep-rooted commitment to deliver consistent quality in every shipment. Our comprehensive quality assurance system ensures that every product — from Feldspar Granules & Powder to Mica Flakes & Scrap — is tested for chemical purity, particle size, moisture, and brightness before dispatch.
We’ve set up state-of-the-art in-house testing laboratories at our plants in Malnas- Rajasthan and Morbi- Gujarat with reliable instruments and skilled personnel to monitor quality at every stage.
Testing Equipment & Facilities
Equipment | Function |
Ball Mill | Used for lab-scale grinding to test grindability and fineness of mineral powders |
Vacuum Disc Filter | Helps in separating solids from slurry in wet ground process; ensures efficient drying analysis |
Particle Size Analyzer (Laser Diffraction) | Ensures particle size uniformity (200–500 mesh) for powder products |
Moisture Analyzer | Measures moisture percentage in both granules and powder |
Muffle Furnace | Determines Loss on Ignition (LOI) at high temperatures for purity verification |
pH Meter | Confirms pH neutrality for use in ceramics, paints, and plastics |
Specific Gravity Apparatus | Confirms density and physical structure consistency |
Color Comparator / Whiteness Meter | Checks brightness and color for ceramic/glass-grade standards |
Magnetic Separator Unit | Removes iron and magnetic impurities to ensure Fe₂O₃ levels stay low |
Quality Control Process
- Raw Material Screening
- Ore sourced from trusted Rajasthan mines is tested for K₂O content, whiteness, and moisture before processing.
- In-Process Sampling
- Quality checks are conducted during crushing, grinding, filtration, and drying.
- Final Product Testing
- Each batch is tested for:
- K₂O, Na₂O, Al₂O₃, SiO₂, Fe₂O₃
- Particle size distribution
- Moisture & LOI
- pH, whiteness, and flowability
- Each batch is tested for:
- Packaging & Dispatch
- Clean, moisture-resistant packaging with batch numbers and lab test results provided for each shipment.
Why MAXSTONE Quality Stands Out:
🧪 Dedicated on-site lab for real-time testing
⚖️ Controlled wet grinding with lab ball mill simulation
💡 Use of vacuum disc for better particle separation in slurry phase
📦 Secure packaging and traceability
