Manufacturer Sandblasting Media Green Garnet Omphacite 30/60 mesh
30/60 mesh Green Garnet Omphacite is a high-performance natural sandblasting media tailored for precision industrial surface treatment and fine blasting projects. Processed from premium omphacite garnet ore via multiple washing, impurity removing, drying and precise grading procedures, this abrasive features ultra-low dust, uniform particle morphology and stable physical properties. It effectively avoids the defects of uneven roughness and excessive residue caused by irregular particles, delivering consistent and delicate blasting results for high-standard surface finishing.
Boasting a Mohs hardness of 7.5–8.0 and excellent structural toughness, 30/60 mesh green garnet has moderate cutting force and outstanding wear resistance. It will not break excessively during blasting, ensuring low consumption and high working efficiency. Free of free silica and harmful substances, the garnet complies with international environmental and safety regulations, effectively preventing construction dust hazards and adapting to long-term industrial operation requirements.
As a classic medium-fine mesh specification, 30/60 mesh garnet is ideal for fine derusting, paint removal, oxide layer cleaning and surface texturing. It can create a uniform, delicate matte roughness on the surface of steel structures, aluminum alloy workpieces, mechanical parts and facility surfaces without damaging the base material. The fine and uniform particles ensure thorough cleaning effect, greatly improving the bonding performance of subsequent spraying, coating and bonding processes.
We supply high-quality green omphacite garnet directly from the factory with stable particle size and reliable quality. This 30/60 mesh sandblasting garnet is widely used in petrochemical equipment, aerospace parts, ship accessory finishing, architectural steel structure treatment and precision machinery industries, serving as a cost-effective and high-quality fine blasting abrasive.
