SEPPE ABRASIVE
25132000
High-performance natural garnet abrasive for sandblasting, surface preparation, rust removal, and industrial cleaning applications.
▸ Garnet sand is a common chemically inert nonmetallic mineral in the natural environment. As a natural alluvial abrasive, its hardness, high specific gravity, chemical stability, and durability make it the ideal blasting media on the market.
▸ It is non-toxic, produces low dust, and causes no pollution — widely used for hardware sand blasting and surface cleaning. As one of the leading garnet abrasive suppliers in north China, SEPPE garnet is thoroughly tested by QC with complete particle size analysis and quality assurance.
▸ Dry Blasting Safety: SEPPE garnet contains less than 1% free silica, dramatically reducing the risk of silicosis compared to silica sand. Its high density produces fewer airborne fines during impact, keeping worksite dust to a minimum.
▸ Wet / Slurry Blasting Compatibility: Garnet's high specific gravity (4.0–4.2) allows it to sink and remain suspended in water-based slurry systems rather than floating. Its chemical inertness means it does not react with water, making it ideal for dust-free wet blasting in environmentally sensitive areas, offshore platforms, and confined spaces.
▸ Low Chloride, No Flash Rust: With chloride content ≤ 25 ppm, our garnet meets the strictest naval and offshore standards for wet blasting, preventing flash rust on steel substrates after blasting.
▸ Non-toxic & Environmentally Friendly: As a natural inert mineral, garnet contains no heavy metals or hazardous leachates, making it safe for use near waterways, in shipyards, and on infrastructure projects with strict environmental regulations.
▸ 20/40 Mesh (Coarse): Heavy-duty rust removal, ship hull cleaning, and thick coating stripping.Suitable for both dry blasting and wet slurry blasting in shipyards.
▸ 30/60 Mesh (Medium): The most versatile grade for general steel surface preparation and maintenance.Ideal for vapour blasting and dustless wet blasting units.
▸ 80 Mesh (Fine): Precise blasting for aluminum, stainless steel, and high-quality waterjet cutting.Also used in fine wet blasting for delicate surface finishing.
▸ Garnet abrasive sand has the greatest potential and is the most widely used in the blasting field. It serves industries closely related to production, such as ship hulls, bridges, pipes, and steel structure sandblasting treatment. It delivers large blasting area per unit time, less sand consumption, and lower overall blasting costs.
▸ With hardness up to 8 Mohs and long service life, garnet produces an ideal angular rough surface on metal, increasing the surface area and improving the bonding force of the interface. This significantly enhances the adhesion of corrosion protection coatings to the metal surface.
▸ High density provides stronger impact force for better metal surface cleaning. Sharp angular edges with reasonable particle size distribution produce less dust and can effectively reach deep into holes and uneven parts to completely remove scale, rust, soluble salts, and other contaminants.
▸ For wet blasting applications, garnet's high density and low chloride content make it the preferred choice over slag or silica abrasives. It provides the same high-quality surface profile without generating airborne dust, ensuring compliance with occupational health and safety regulations in shipyards, offshore rigs, and municipal projects.
▸ Raw alluvial garnet → Washing & Desliming → Gravity Separation → Drying → Magnetic Separation → Precision Screening → Final Inspection & Packaging
▸ Each production stage removes impurities and excess fines, producing consistently sharp grains with tight size control for reliable abrasive flow.
▸ Particle size distribution testing per ASTM E11 — strict control of 20/40, 30/60, and 80 mesh grades.
▸ Bulk density and specific gravity verification on each production batch.
▸ Moisture content below 0.5% to ensure free-flowing abrasive and prevent nozzle clogging.
▸ Salt/chloride content testing to prevent rust formation on blasted steel surfaces.
▸ Free silica and heavy metal analysis to meet HSE requirements.

▸ 25 kg PP woven bags and 25 kg paper bags available
▸ 1 MT jumbo bags for bulk supply
▸ OEM private label and custom packaging supported
▸ Reliable container shipment to all major ports worldwide
▸ Typically 3‑5 times depending on blasting pressure and material, thanks to its high toughness and low friability.
▸ No. Our garnet has less than 1% free silica, making it a much safer alternative to silica sand blasting.
▸ 30/60 mesh is the most versatile grade for general steel blasting. Use 20/40 for heavy rust removal and 80 mesh for fine finishing work.
▸ Yes. Garnet is a natural inert mineral, non-toxic, produces low dust, and contains no hazardous substances.
▸ Yes. Free samples and technical documents (TDS/SDS) are available upon request.
▸ Yes. SEPPE garnet is specifically designed for both dry and wet blasting. Its high specific gravity ensures proper slurry suspension, while its inert chemistry and low chloride prevent water contamination and flash rust. It is widely used in vapour blasting, wet slurry blasting, and dustless blasting systems in environmentally regulated areas.
