92% Aluminium Grinding Balls are an important engineering ceramic and belong to high-tech products. 

Due to the characteristics of suitable hardness, moderate density, wear resistance, corrosion resistance, low price, and the introduction of metal impurities in metal balls. 92% Aluminium Grinding Balls are widely used in the grinding and processing of white cement, minerals, ceramics, electronic materials, magnetic materials, and raw materials in industries such as coatings and paints.

Chemical Industry

In the construction ceramic industry, the wear efficiency of alumina ceramic balls is higher than that of natural flint and pebbles. 

With the reduction of high-quality natural spherical stone resources and the high wear rate of ordinary ceramic balls, alumina ceramic balls will be increasingly used by ceramic manufacturers. 

According to different alumina contents, they can be divided into medium aluminum balls, medium high aluminum balls, and high aluminum balls. 

Generally, we classify those with 60% -65% alumina content as medium aluminum balls, those with 75% -80% alumina content as medium high aluminum balls, and those with more than 90% alumina content as high aluminum balls. 

High alumina balls are further divided into 90 porcelain, 92 porcelain, 95 porcelain, and 99 porcelain. Due to its extremely high production costs, 99 porcelain is rarely produced in large quantities by large manufacturers, mainly through manual production by some special ceramic factories.

alumina grinding balls from Gaoteng   packing of alumina grinding balls

Medium aluminum balls and medium high aluminum balls are accepted by most ceramic factories due to their lower prices, mainly used for grinding ceramic billets. 

High aluminum balls are widely used for precision and deep processing of thick and hard materials in different types of ceramics, enamels, glass, chemical and other factories due to their excellent properties such as high strength, high hardness, high wear resistance, large specific gravity, small volume, high temperature resistance, corrosion resistance, and pollution-free.

 Among them, high aluminum balls with a content of 92%  are the most commonly used.
