Introduction
Alumina ball, also known as modern water purification activated bauxite, is a porous, highly dispersed solid material and has the characteristics required by the catalyst. Therefore, it is usually used as a catalyst in the chemical industry. According to the physical properties of alumina, alumina can be divided into three types: sand, flour and intermediate.
Advantages
These three types of alumina have great differences in physical properties. Alumina grinding balls has smaller bulk density, larger specific surface area, slightly smaller repose angle, contains a small amount of a-Al2O3, has more and uniform coarse particles and high strength. Flour alumina has large bulk density, small specific surface area, more a-Al2O3, more fine particles and poor strength. The physical properties of intermediate alumina are between the two.
Application
Used for cement factory and ceramic factory powder equipment, especially suitable for dry grinding products.
Grinding balls are grinding bodies used for fine grinding equipment such as ball mills, pot mills, vibratory mills and so on. It can be subdivided into two types: wet grinding and dry grinding.
Property
Formed by isostatic pressure molding, good toughness, can greatly improve the grinding efficiency, reduce the material wear, reduce the grinding time.
