Absolute Purity.
Batch After Batch.
In industrial compounding, even a 1% drift in particle sizing or moisture can cause nozzle clogs and pigment streaks. Our laboratory infrastructure guarantees certified consistency across every dispatch.
Scientific Instrumentation & Testing
Every mineral lot manufactured at our Alwar processing plant is tested across physical, optical, and chemical vectors.
Malvern Mastersizer 3000
Measures precise D10, D50, and D97 particle distributions to prevent oversized grit and ensure optimal polymer melt-flow index.
HunterLab UltraScan PRO
Verifies L*a*b* optical values and Hunter/ISO whiteness to guarantee minimum 96.0%+ brightness for masterbatches and emulsion paints.
Karl Fischer Coulometer
Quantifies moisture content down to 0.05%, preventing foaming, surface defects, and pinholes during high-temperature polymer extrusion.
Acid Insoluble & XRF Testing
Verifies chemical percentages (CaCO₃, MgCO₃, Na₂SO₄, SiO₂) and confirms heavy metal non-detectability for sensitive applications.
4-Stage Quality Gate & Batch Release
Mineface Geological Selective Mining
Raw mineral boulders are spectrally graded at the quarry face in Alwar before haulage to eliminate silica contamination at source.
Multi-Stage Crushing & Magnetic Separation
Jaw and impact crushers reduce stone size while high-intensity rare-earth magnetic drums extract any metallic iron particles.
Ultra-Fine Ball Milling & Dynamic Vortex Air Classification
Closed-circuit centrifugal air classifiers separate particle cuts in real-time, cycling back oversized grains until exact micron targets are achieved.
Quarantine & Laboratory CoA Sign-Off
Every finished 25 MT lot is retained in quarantine silos until all 5 NABL-standard parameters pass before automated packing and dispatch.
Need a Lot-Specific Certificate of Analysis (CoA)?
We provide full chemical assay sheets, D50/D97 laser diffraction curves, and heavy metal testing certificates with every sample and commercial dispatch.
