92% 95%Al2O3 Alumina Ceramic Ball/ Balls For Cement Grinding
Description
Technical Parameters
Product Introduction
Our alumina ceramic ball is made of α alumina(α-alumina oxide, the most thermodynamically stable form) by cool isostatic pressing or rolling, then fired at a very high temperature in the tunnel kiln. It is an ideal grinding media.
Advantages
High strength and high hardness,
Ultra high wear resistance, can prolong the service life of the machine small volume,
High temperature and corrosion resistance and acid and alkali resistance,
Without any pollution, no impact on the quality of grinding materials;
Application
petroleum, chemical, fertilizer, natural gas and environment protection etc.
