Classification of alumina ceramic grinding balls
Aluminum oxide ceramic grinding balls can be divided into medium aluminum balls, medium high aluminum balls, and high aluminum balls according to the different content of aluminum oxide.
Medium aluminum balls: usually made from 60% to 65% aluminum oxide content.
Medium to high aluminum balls: usually made from 75% to 80% aluminum oxide content.
High alumina ball: usually made of over 90% alumina content, further subdivided into 90 porcelain, 92 porcelain, 95 porcelain, and 99 porcelain.
In addition, according to different uses, alumina ceramic grinding balls can also be divided into ceramic filler balls and ceramic grinding balls.
Applications:
The specific applications of alumina ceramic grinding balls are wide, and the following are some main application areas:
1.Cement plant: Aluminum oxide ceramic grinding balls have excellent wear resistance and can be used for a long time, reducing production costs. At the same time, their chemical properties are stable and will not pollute the raw materials.
2.Ceramic Factory: Ceramic factories need to use grinding balls to grind ceramic raw materials for subsequent molding and firing. Aluminum oxide ceramic grinding balls have advantages such as high strength, high hardness, and high wear resistance, which can meet the production needs of ceramic factories.
3.Glass factory: In the glass production process, it is necessary to use grinding balls to finely grind the glass raw materials to improve the transparency and quality of the glass. Aluminum oxide ceramic grinding balls have excellent wear resistance and chemical stability, which will not pollute glass raw materials and can improve the quality of glass.
4.Chemical plant: During the chemical reaction process, it is necessary to use grinding balls to finely grind the chemical raw materials, in order to improve the efficiency of the chemical reaction and the quality of the products. Aluminum oxide ceramic grinding balls have excellent wear resistance and chemical stability, do not pollute chemical raw materials, and can improve the efficiency of chemical reactions and the quality of products.
In addition, alumina ceramic grinding balls are also widely used in fields such as electronics, medicine, and environmental protection.

Production process:
The processing process of alumina ceramic grinding balls mainly includes the following steps:
1. Raw material preparation: Select high-purity aluminum oxide as the raw material, and grind and screen it to ensure uniform particle size of the raw material.
2. Mixing and molding: Mix fine powdered alumina raw materials with a certain proportion of binder, and add a certain proportion of water to form a paste like mixture. Then, use a press or injection molding machine to shape the mixture, common molding methods include dry pressing and injection molding.
3. Drying: Properly dry the formed ceramic balls in a drying chamber to remove moisture and ensure the stability of the ceramic balls.
4. Sintering: Place the dried ceramic balls into a high-temperature furnace for sintering. Under high temperature, the bonding force between ceramic ball particles gradually increases, forming a dense material structure. The control of sintering temperature, time, and atmosphere has important effects on the performance of ceramic balls.
5. Surface treatment: The surface of sintered alumina ceramic balls may have some defects, and surface treatment can be carried out through grinding and polishing to improve the smoothness and flatness of the ceramic balls.
6. Testing and packaging: Conduct appearance quality, dimensional accuracy, hardness and other performance tests on ceramic balls. After passing the tests, package and store them for future sales and use.
