Description
Aluminum oxide ball, alumina ball for processing hard mineral include ceramic, glazes and chemicals.
Aluminum oxide (Alumina) grinding balls refer to materials such as bauxite, roller powder, industrial alumina powder, high-temperature calcined alpha alumina powder, etc., after batching, grinding, milling (pulping, mud making), forming, drying A ball which is widely used as a grinding medium, which is produced by a process such as firing. According to different alumina content, it can be divided into medium aluminum ball, medium high aluminum ball and high aluminum ball.
Generally, we classify 60%-65% alumina content as medium aluminum ball, 75%-80% alumina content as medium-high aluminum ball, and 90% or more alumina content as high-aluminum ball. Among them, the high aluminum ball is subdivided into 90 porcelain, 92 porcelain, 95 porcelain and 99 porcelain. Due to its extremely high production cost, 99 porcelain is rarely manufactured in large quantities by large manufacturers. At present, it is mainly made by hand in some special ceramic factories.

Product Applicatiion:
Aluminum oxide balls are mainly used for finishing and deep processing hard materials of different types of ceramics, glazes, glass and chemical factories. It is the grinding medium of ball mill, pot mill, vibration mill and other fine powder grinding equipment. Its grinding efficiency and wear resistance are much better than ordinary pebble or natural pebble.
Non-metallic mineral products powder (such as zirconium silicate, kaolin, heavy calcium carbonate, etc.) and coatings, paints and other industries of material grinding and dispersion as well as polishing of metal parts, suitable for all types of grinding and polishing equipments.
The medium aluminum ball and the medium high aluminum ball are accepted by most ceramic factories because of their low price, and are mainly used for grinding ceramic blanks. Due to its high strength, high hardness and high wear resistance, high-aluminum balls are widely used in different types of ceramics, enamels, glass and chemicals due to their superior characteristics, small volume, high temperature resistance, corrosion resistance and pollution-free properties. Such as the factory's thick and hard material finishing and deep processing, especially the 92-content high aluminum ball is most commonly used.
