The Characteristics and Applications of Alumina Ceramic Liner with hole

图片
Alumina ceramic liner with hole , mainly composed of high-purity α-alumina (Al₂O₃) through high-temperature sintering, typically has an alumina content higher than 92%. This type of liner has a flat plate structure, with a through-hole on the surface. The hole diameter and spacing can be designed according to application requirements. Its performance characteristics include high hardness, excellent wear resistance, good chemical corrosion resistance, and outstanding high-temperature resistance, with a working temperature of up to 1600 degrees Celsius. Moreover, its structural design takes into account both lightweight and mechanical strength, making it convenient for installation and maintenance. In the industrial field, alumina ceramic liner with hole is widely used in material conveying systems, equipment protection, and ventilation and dust removal devices. For instance, in industries such as thermal power generation, cement production, and steel smelting, they are employed as inter...

Characteristics and Applications of Alumina Ceramic Grinding Balls

图片
Alumina ceramic grinding balls are mainly made by high-temperature sintering of high-purity α -alumina. Their alumina content is usually above 90%, and some can reach over 99%. This material features high hardness, excellent wear resistance, superior corrosion resistance and thermal stability. Its density typically ranges from 3.6 to 3.9 g/cm ³ , and its Mohs hardness can reach up to 9. Due to its dense structure and high chemical inertness, it is unlikely to introduce impurities during the grinding process and can withstand strong mechanical shocks and thermal stresses. Alumina ceramic grinding balls are widely used in grinding processes in the fields of building materials, coatings, electronic materials, mining and chemical industries. In ball mills, they are used for grinding cement, mineral raw materials, ceramic glazes and magnetic materials, effectively enhancing grinding efficiency and reducing product contamination. In the ultrafine grinding of dyes and positive and negative el...
