Abrasive material "Black Grit"

Low-salinity blasting material used in vessels around the world.

"Black Grit" is a sandblasting abrasive with a consistent grain size and high grinding capability, offering excellent cost performance. It has about twice the strength of silica sand and features sharp protrusions on its surface, making it highly effective for removing mill scale and corrosive rust due to its large impact marks. It is widely used for polishing ship hulls in shipyards, steel materials for bridges, and surface preparation of various tanks. Additionally, raw products are utilized as aggregates for concrete precast products. 【Features】 ■ High density due to a high iron content, exceeding the specific gravity of natural sand ■ Grinding speed is faster, proportional to the hardness and specific gravity of common abrasives ■ Generates very little silica and dust compared to sand ■ Acts like small cutting tools due to sharp protrusions and numerous iron particle grains on the surface ■ Extremely effective in removing mill scale and corrosive rust due to large impact marks *For more details, please download the PDF or feel free to contact us.
