1.YN BauxiteBauxite is earthy mineral which consists mainly of Al2O3 , a kind of hydrated alumina containing impurities. According to the usage, It can be divided into the levels of Metallurgy, chemical industry, grinding, cement, and refractory. Clinker is pale yellow and dark grey. It is mainly used for high aluminum refractory material, and also can be used to make the fused corundum. Our factory supply mainly YN - 88 bauxite , YN - 84 bauxite and YN - 85 bauxite.2.YN Brown Fused Alumina Section SandThe main component of brown fused alumina section sand includes: high quality bauxite, anthracite, scrap iron, its fabrication adopts modern new unique technology. It has short grinding time, high efficiency, good economic returns, low price. Brown fused alumina is superior to other abrasives because it has conchoidal fracture, the edge and corner of this conchoidal are sharp. These edges and corners can form new edge and corner in continuous grinding. The most important characteristics of brown fused alumina are high hardness, high-density, stable chemical properties and strong self-sharpening. So, it is the best choice for sand blasting process and grinding and polishing, at the same time, brown fused alumina can be used to sandblasting derusting cleaning artifacts and refractory material.3.YN Brown Fused Alumina Grit SandBrown fused alumina grit sand is made of bauxite, scrap iron and anthracite smelted in electric arc furnace at more than 2000 centigrade high temperature. Then, it was crushed by autogenous mill, removed the iron through magnetic separation, screened to variety granularity. It has dense character and high hardness. The particle shape is globular. It is applicable to manufacture ceramics, resinoid high bonded abrasive tools, grinding abrasive, polishing materials, sand blasting and precision casting. It is also used to manufacture high grade refractory. The specification of the grit sand produced by our company is F4#-F240#.
