Types of Industrial Grinding Ceramic Balls
Industrial grinding ceramic balls are mainly divided into three types: silicon carbide grinding ceramic balls, microcrystalline alumina grinding ceramic balls, and high alumina grinding ceramic balls.
Grinding ceramic balls are grinding bodies used in fine grinding equipment such as ball mills, pot mills, and vibration mills. Grinding ceramic balls have the advantages of high hardness, high mechanical strength, high volume density, good wear resistance and corrosion resistance. It is an economical and widely used non-metallic grinding medium. Grinding ceramic balls are mainly used in machinery, electronics, aerospace and other fields, and can also be used in fertilizer and chemical industries.
Atmospheric pressure sintered silicon carbide (SSiC) for silicon carbide grinding ceramic balls is made of fine silicon carbide powder mixed with sintering aids and sintered in an inert atmosphere at 2000-2200 degrees. It is a high-performance silicon carbide ceramic with good With thermal shock resistance, heat conduction and high wear resistance, it is an ideal material for manufacturing chemical pump sealing rings, shaft sleeves, high temperature nozzles and wear-resistant plates.
Microcrystalline alumina grinding ceramic ball: the most commonly used in industrial production is classified as medium aluminum ball with an aluminum content of 60%-65%, medium-high aluminum ball with an aluminum content of 75%-80%, and high-alumina ball with an aluminum content of more than 90%. aluminum balls. Due to the high content of alumina, high density, high hardness and high wear resistance, it is widely used in fine grinding and cutting of thick and hard materials in different types of ceramics, enamel, glass, and chemical factories.
High alumina grinding balls are subdivided into 90 porcelain, 92 porcelain, 95 porcelain and 99 porcelain. Due to its extremely high production cost, 99 porcelain is rarely produced in large quantities by large manufacturers. At present, it is mainly made by hand in some special ceramic factories. With the characteristics of high hardness, high density, low wear, good regularity, and corrosion resistance, high-alumina grinding balls are the most ideal high-efficiency grinding media for grinding glazes, blanks and various mineral powders.
