Alumina Ceramic Cylinders as Ceramic Grinding Media with Low Wear Loss
Introduction:
Our normal specification of high alumina ceramic cylinder as ceramic grinding media: φ15,φ20,φ25,φ30/40/50/60, and the hardness can change according to diameter, espect these, the ceramic cap such as φ17.5, φ22.5, φ23.5 also can used as ceramic grinding cylinder.

Features
High alumina ceramic cylinder produced by our company are formed by dry powder isostatic pressing, with complete specifications, high purity, good compactness, high hardness, low wear, corrosion resistance, and easy installation.
Application
High alumina ceramic cylinder due to its high strength, high hardness, high wear resistance and high specific ratio, small volume, high temperature resistance, corrosion resistance, less pollution and other excellent characteristics are widely used in different types of ceramic, porcelain glaze, glass, chemical and other factories of thick and hard material finishing and deep processing, ball mill, tank mill, vibration mill and other fine grinding equipment grinding body. Grinding efficiency and wear resistance are better than ordinary pebble or natural pebble.
