Almandine Garnet Sand
Crushed from natural high-density Almandine rock garnet deposits, processed through multi-stage wet washing, magnetic separation, and precision optical screening. Features ultra-low soluble chlorides (≤15 ppm), zero free silica (<0.1%), and sharp sub-angular edges for smooth CNC waterjet cutting and high-speed Sa 2.5/Sa 3.0 blast cleaning.
Smelting Precision & Grain Morphology Control
Industrial abrasive performance depends on crystal phase purity, bulk density (LPD), and zero oversize contamination. At our Gongyi smelting and sizing complex, every ton of Almandine Garnet Sand undergoes controlled fusion, impact shaping, and high-Gauss magnetic extraction.
Crushed Rock Garnet vs. Rounded Alluvial Beach Garnet
Unlike soft, rounded beach sand garnet, our Almandine garnet is crushed from hard rock ore—creating sharp, sub-angular dodecahedral cutting edges that increase CNC waterjet cutting speed by 15–25% and produce uniform anchor profiles.
Guaranteed Uninterrupted Flow in 0.76mm & 1.02mm Nozzles
Every batch of 80 Mesh and 120 Mesh waterjet garnet undergoes double safety scalping on precision vibrating screens to eliminate 100% of oversize particles, protecting your carbide focusing tubes from costly downtime.
Low Conductivity & Dust-Free Shipyard Blasting
Triple washed in fresh low-chloride water and rotary dried (<0.2% moisture) to achieve conductivity ≤15 mS/m and soluble chlorides ≤15 ppm—preventing salt contamination and flash rusting under marine epoxy coatings.
Chemical Composition & Physical Parameters
Verified by in-house XRF fluorescence spectrometry and W.S. Tyler Ro-Tap mechanical sieve analysis. A signed Certificate of Analysis (COA) accompanies every shipment.
Available Grit Sizes & Particle Distribution Matrix
Precision-classified across multi-deck vibrating screens and air/water elutriation lines to meet strict international FEPA, JIS, and ASTM sieve tolerances.

Engineered for Heavy Industrial Performance
Consistent chemical purity and controlled grain geometry make our Almandine Garnet Sand a trusted raw material for global grinding tool, blasting, and refractory manufacturers.
4-Stage Metrology Lab Inspection & Batch Traceability
Every production lot is tested in our ISO 9001:2015 Gongyi laboratory before bagging. No shipment leaves our warehouse without a verified Certificate of Analysis.
X-Ray Fluorescence Chemical Analysis
Quantitative verification of primary crystal content and trace oxides (Fe2O3, SiO2, Na2O, TiO2) per GB/T and ISO analytical standards.
Ro-Tap Sieve & Laser Diffraction
Macro grits are tested on W.S. Tyler Ro-Tap sieve shakers; micro-powders are analyzed via Malvern laser diffraction for D10/D50/D90 accuracy.
Bulk Density (LPD) & Magnetic Check
Loose packed density, true specific gravity, moisture (<0.2%), and residual magnetic iron are measured to guarantee lot-to-lot consistency.
Signed COA & 12-Month Sample Retention
Each batch receives a traceable barcode and signed COA. A sealed 500g reference sample is archived in our lab for 12 months.
Moisture-Proof Export Packaging & Container Loading
Engineered to prevent bag tearing, moisture ingress, and pallet shifting during long-haul ocean freight from Qingdao, Tianjin, or Shanghai ports.
