Ceramic balls are alumina grinding balls specially developed for cement dry grinding. Not only has high strength, but also good toughness. The structural characteristics of its alumina ceramic ball are mainly reflected in the chemical composition of alumina grinding ball ceramic products is Al2O3, accounting for 90%. The molding process is mainly divided into two categories: pressing and rolling. There are various specifications to choose from. The diameter is less than 20mm for rolling, and the diameter is greater than 20mm for pressing.
The physical properties of the alumina ceramic ball and its own structural characteristics can be applied to various processes of the dry cement final grinding system, especially the combined grinding system of the roller press and the ball mill, but only the average particle size of the abrasive is required. Less than 1mm. And some high-quality oxidized ceramic balls can be used in place of steel balls in the grinding chambers (tails) of other open-closed cement grinding ball mills.
