Our garnet sand is rock type garnet mined from natural garnet rocks 200 meters underground.
It goes through crushing,magnetic separation,washing and drying production procedures.Being crushed from natural garnet rocks, our garnet sand has high hardness and sharper edges. With many times magnetic separations to remove impurities,it keeps high qualified red grains. Then several times washing removes the powder away. After screening of sifting bed,each size has the uniform particle distribution.
