Rolled cement alumina ball has high wear resistance, and the wear resistance of alumina ball is higher than that of ordinary alumina ball.In the process of grinding, the ball will not pollute the grinding material, so as to maintain the purity of the grinding material and improve the stability of the grinding material, especially the ceramic glaze.
