Product Description Product DescriptionIntroduction:High alumina grinding balls refer to materials such as bauxite, roller powder, industrial alumina powder, and high-temperature calcined Alpha alumina powder as raw materials, after batching, grinding, milling (pulping, mud making), forming, and drying , Sintering and other processes, mainly used as a grinding medium and widely used ball stone. According to different alumina content, it can be divided into medium-aluminum balls, medium-high aluminum balls and high-aluminum balls. High alumina balls, with more than 90% alumina content are high alumina balls. Among them, the high-alumina balls are subdivided into 90 porcelain, 92 porcelain, 95 porcelain and 99 porcelain. Due to its extremely high production cost, few large-scale manufacturers manufacture 99 porcelain in large quantities. At present, it is mainly made by hand by some special ceramic factories.Chemical analysis of RTO Heat Exchange Honeycomb Ceramic WORK SHOP Technical Parameter:ModelChemxin 99ColorWhiteShapeBallTypical Technical CompositionMin. % Max. %Usual%SiO2****** 0.20.18Al2O399 99.699.3Fe2O3****** 0.20.02TiO2****** 0.550.02CaO****** 0.10.02MgO****** 0.10.05Na2O****** 0.250.01K2O****** 0.20.13Physical propertiesIndex Value ValueLeachable Iron≤ 0.01% ******Apparent Porosity by Weight≤ 7.0%******Moh's Hardness Scale>8.0******Water Absorption<4.0 wt.%****** Acid Resistance>99.8%******Thermal Conductivity0.7-0.8 w/m2.k******Thermal Expansion @ 5000.10%******Thermal Shock Stability, 1000 then water cooling10 times******Max.
