Alumina grinding ball is undoubtedly better grinding and wear resistance, so what are the factors that affect alumina grinding ball?

 

First of all, the selection of raw material Al203.The choice of Al203 directly affects the final product quality and grinding performance of alumina ball.The particle size of Al203 raw material also directly affects the abrasion resistance of alumina grinding ball.

 

The second is to select the appropriate sintering assistant, through the sintering assistant to reduce the sintering temperature of alumina grinding ball, so as to improve the ceramic microstructure and mechanical properties of alumina grinding ball, and then improve the wear resistance of alumina grinding ball.

 

In addition, alumina grinding ball formation process.Roll molding and isostatic forming technology, to change the other molding hollow, stratification and other uneven shortcomings.

 

When suitable sintering methods are adopted, such as low temperature and fast combustion, the energy saving effect will be greatly improved. The grain growth of alumina grinding ball is also controlled, which improves the strength and toughness of alumina grinding ball, and increases the wear resistance of alumina grinding ball.
