What are the differences between alumina grinding balls and zirconia grinding balls
Aluminum oxide grinding ball is generally used to grind media, which has the characteristics of low price and low wear. What is the difference between these two different types of products?
1. Alumina grinding ball. It refers to the use of bauxite, roller powder, alumina and high-temperature calcination α The alumina powder is the raw material and needs to be made through the process of mixing, crushing, grinding, molding, drying and sintering. It is mainly used for the function of grinding medium and is widely used. It can also be divided into medium aluminum ball, medium high aluminum ball and high aluminum ball according to the different content of aluminum oxide.
2. Zirconium oxide is strictly required to use rare earth yttrium oxide as stabilizer, and raw materials with high whiteness and fineness are used. It has the characteristics of high grinding efficiency, good fluidity of zirconium ball, good roundness of product, smooth surface, etc. In addition, it also needs impact resistance and low wear resistance.
Among them, alumina grinding ball is accepted by most ceramic factories because of its low price and is used for grinding ceramic blanks. In addition, because of its high strength, high hardness, high wear resistance, small size, high temperature resistance and corrosion resistance, it is widely used for thick and hard materials and deep processing in different types of ceramics, enamel, glass, chemical and other plants.
The above is the difference between zirconia grinding ball and alumina grinding ball. It is not difficult to see that there is a big difference between the two products in use. We can choose products that are more suitable for us according to our own needs.
