High aluminum ball is a category of alumina ball, and is referred to as high aluminum ball due to its high alumina content.High aluminum ball can be subdivided into 90,92,95,99 and other series.

High aluminum ball is widely used for its high strength, high hardness, high wear resistance, large ratio, small volume, high temperature resistance, corrosion resistance, no pollution and other excellent characteristics, and is widely used in different types of ceramic, porcelain glaze, glass, chemical industry and other factories of thick and hard materials of fine processing and deep processing.

Take the high aluminum ball with 92% content as an example, its specific gravity (density) should reach more than 3.60, the alumina content reaches more than 91.5%, low in iron.The same raw material, the same formula, the same firing temperature, the smaller the fineness of the raw material after grinding, the higher the proportion, the better the wear resistance.The specific proportion of high aluminum ball is mainly affected by powder and burning, burning raw (not cooked), too coarse powder, adding miscellaneous materials and other factors will lead to the specific proportion of ball stone is not enough.Low proportion of the ball stone is not wear-resistant, easy to crack, but the high proportion can not represent the ball stone must be wear-resistant, because excessive sintering ball stone can also reach a high proportion.

The most important quality of ball stone is wear resistance, some testing institutions can show the quality of ball stone, but the data is for reference only, because the laboratory testing environment conditions and the production environment is very different, the first test is water mill, and many manufacturers are dry grinding; secondly, there is no other raw materials, just friction between ball stone and ball stone, and the actual production process is to add a variety of raw materials.In the actual use process, to detect the wear of ball stone, we must make more records, after the initial ratio, by recording the number of added ball stone, combined with the output, calculate the ball stone in production, so as to compare the cost of high aluminum ball and other grinding ball, and also the quality of ball stone can be compared between the manufacturers.In addition to the hardness and fineness of the ball stone grinding, there are also grinding methods (different, such as dry grinding and wet grinding), the speed of the ball mill, the ratio of the ball stone is reasonable, the viscosity of the material and other factors.

The main producing areas of ordinary high aluminum balls in China are Shandong and Foshan, Guangdong province. Shandong brands include Sinoma, Kunpeng, East Porcelain, etc., Foshan has Gogh and Special, among which Sinoma has the largest scale and output, and the quality of its micro beads is recognized by domestic and foreign counterparts and customers, and the product quality of Wanfu is the most stable.
