Abrasive material "Black Grit"

Low-salinity blast material used in ships 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, resulting in significant impact and exceptional performance in removing mill scale and corrosion rust. It is widely used for polishing ship hulls in shipyards, steel materials for bridges, and surface preparation of various tanks. The raw product is also utilized as aggregate for concrete precast products. 【Features】 ■ High density due to a high iron content, with a specific gravity exceeding that of natural sand ■ Grinding speed is faster, proportional to the hardness and specific gravity of typical abrasives ■ Generates minimal 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 corrosion rust due to significant impact *For more details, please download the PDF or feel free to contact us.
