*The above specifications are typical specifications of inert alumina grinding balls. We can customize other different sizes of alumina grinding balls according to your requirements
The main raw material of alumina grinding balls is alumina powder. After the ceramic is formed by rolling and isostatic pressing, it needs to be calcined at a high temperature above 1600°C. Alumina ceramics are divided into inert alumina balls and activated alumina balls. Inert balls are mainly used for grinding in industry. Its characteristics include good wear resistance, low wear, chemical inertness, and chemical corrosion resistance. Grind ceramic glazes, etc. in various ball mills and pulverizers.
Our alumina wear-resistant balls mainly have two types of purity, 92% and 95%, and also have a variety of sizes for you to choose from: microbead sizes include 0.2-0.4mm, 0.5-1mm, 1.0-1.2mm, etc. Slightly larger grinding ball sizes are 1-90mm.
