3D Foundry Sand Sieve & Permeability Analyzer
Calibrate your foundry core & green sand mould performance in real-time. Gujarat Minerals processes sub-angular, triple-washed, kiln-dried high-purity silica sand (>99.2% SiO₂) engineered to exact ASTM & AFS grain distribution standards.
Interactive Foundry Sand Sieve & Permeability Analyzer
Simulate 3D vibratory sieve gradation and calculate mould permeability, grain fineness (AFS GFN), and refractoriness in real-time.
ASTM Sieve Distribution (%)3-Screen Spread Standard
Gujarat Minerals dispatches 1-2 KG calibrated test samples anywhere in India within 48 hours.
Why 3-Screen Distribution Matters
Foundry sand with a controlled 3-screen spread prevents gas entrapment while maintaining optimal green compression strength. Our double hydro-cyclone classification guarantees >75% grain accumulation across consecutive sieves.
Ultra-Low Acid Demand (ADV < 3.0)
High acid demand value (ADV) leads to resin binder wastage in cold-box and no-bake core making. Gujarat Minerals silica sand is thoroughly deslimed to ensure ADV < 3.0, saving up to 18% in binder consumption.
Kiln-Dried 0.00% Moisture Guarantee
Every batch undergoes industrial rotary kiln drying and magnetic separation, ensuring zero free moisture to eliminate steam explosion defects and pinhole porosity during molten metal pouring.
