The Advantages of Alumina Ceramic Balls as Powder Grinding
The specific reasons for the use of alumina grinding balls as grinding media in powder processing can be further refined into the following points:
High hardness and wear resistance: Alumina (especially α-AL2O3 crystal) has extremely high hardness, which makes it not easy to be worn during friction with other materials, thus maintaining a long service life. The characteristics of good wear resistance reduce the media consumption in the grinding process and reduce the production cost.
Stable physical and chemical properties: alumina grinding ball in a variety of environments have shown good chemical stability, not easy to react with most substances, to ensure the stability of material properties during the grinding process, to avoid the introduction of impurities.
High temperature resistance: In powder processing, some materials or processes may need to be carried out under high temperature conditions. Alumina grinding balls can withstand higher temperatures without deformation or damage, ensuring effectiveness and reliability in high-temperature grinding environments.
Low water absorption and non-expansion of water absorption: This feature is essential to maintain dimensional stability and grinding efficiency of the grinding medium. The low water absorption means that the ball also does not gain weight or expand significantly in a wet environment, thus avoiding a reduction in grinding efficiency due to size changes.
The larger proportion makes the alumina grinding ball have higher impact force and crushing capacity during the grinding process, which helps to refine the material faster and improve the grinding efficiency.
No metal impurities: Since alumina is a non-metallic material, it will not introduce metal impurities into the material during use, which is particularly important for the production of electronic materials, magnetic materials, refractories and other products requiring high purity.
Wide range of applications: Based on the above advantages, alumina grinding ball is widely used in ceramic, cement, building materials, paint, paint, fertilizer, glass, enamel and other industries of powder processing, especially in the ground medium requirements of high occasions, such as electronic materials and white cement grinding processing.
