Alumina Ball. Our alumina ball is made of α alumina (α aluminium oxide, the most thermodynamically stable form) by cool isostatic pressing and fired at a very high temperature in the tunnel kiln. Our alumina ball product series include: alumina grinding ball for ball mill grinding media and inert alumina ball for tower packing, alyst bed support, column .
Ceramic grinding media are also suited for use in processes where mixing and dispersing effects play an important role. In the majority of these grinding processes, steatite and alumina are the most common ceramic materials used for grinding balls and linings. CeramTec generally manufactures its grinding balls and linings with steatite.
