Brown garnet sand is a tough rock type used to make abrasive powder. Which is brownish-black or dark gray in color. It is the hardest mineral after diamond, making it the second hardest mineral with a Mohs hardness value of 9. Brown garnet sand largely consists of the mineral corundum (aluminum oxide), mixed with other species such as the iron-bearing spinels hercynite and magnetite, and also rutile (titania). The Crushed or naturally eroded emery (known as black sand) is used as an abrasive, for example, on an emery board, as a traction enhancer in asphalt and tarmac mixtures, or as used in mechanical engineering as Emery cloth.
Brown Garnet Sand Application
The main application in water jet cutting, sandblasting, coatings removal, surface preparation, water filtration, and other specialized applications.

Brown Garnet Sand Production Technical Process
Natural garnet / natural emery will go through crushing, magnetic separation, washing anddrying production procedures. Being crushed from natural garnet rocks, it has high hardness, and more Sharpe does. With repeatedly magnetic separations to remove impurities, it keeps high qualified grains. Then several times washing to remove the powder away. After the screening of sifting bed, each size has a uniform particle distribution.
Brown Garnet Sand Package & Shipping
After confirmation of cargo in good condition(packing sound), the cargo can be loaded in CONTAINER, sealing the container and finally shipping it from the loading port. You will receive the bulk products at your destination port after about 7- 20 days.
