Technical Parameters
Products Description
The alumina content is an important indicator for measuring the performance of alumina ceramic grinding balls, with common contents of 92%, 95%, 99%, and up to 99.99% or more. There are significant differences in performance and application scenarios between alumina ceramic balls of different purities.
92% purity alumina ceramic balls, due to their relatively low cost, are widely used in some ordinary industrial fields where product purity requirements are not particularly stringent, such as grinding ordinary building ceramic powders and crushing general glass raw materials.
As the purity increases to 95%, its wear resistance and chemical stability are further enhanced, making it suitable for industries that require certain powder quality, such as the initial grinding of electronic ceramic powders. 99% pure alumina ceramic grinding balls have higher hardness and better wear resistance, suitable for scenarios that require high material purity and grinding accuracy, such as the processing of advanced optical glass powders. And 99.99% and above ultra-high purity alumina ceramic balls are almost free of impurities, and are used as grinding media in some industries that require almost extreme product quality, such as high-end biopharmaceutical fields, to ensure that no impurities are introduced that affect the purity and quality of drugs. Our HUAO company can customize alumina ceramic balls with different contents according to customer needs.
Advantages of alumina ceramic grinding balls
The hardness of alumina ceramic grinding balls is as high as 9 on the Mohs scale, which is almost twice that of any metal material and other ceramic materials. Its high hardness gives it strong resistance to compression and wear, making it difficult to be worn and deformed.
During the grinding process, they rarely break and the pollution factor is minimal. Under the same grinding conditions, the grinding efficiency and wear resistance of alumina ceramic grinding balls are both high. Due to their excellent characteristics, they are widely used in the precision and deep processing of thick and hard materials in different types of ceramics, glass glazes, glass, chemical and other factories, with 92% of high alumina balls being the most commonly used.
high hardness and wear resistance
ensuring a longer lifespan and less frequent replacement, resulting in cost savings.
good chemical stability
making them resistant to corrosion and reaction with grinding materials, ensuring purity of the final product.
High density
The bulk density is above 3.6g/cm³, and the grinding efficiency is high.
Strong customization
Water absorption and dimensions can be customized according to customer requirements.
