Calcined alumina of high-temperature and low sodium adopted, grinded by large-tonnage ball mill, centrifugal granulation, dry powder CIP shape. The density has been improved. Density equality, ball roundness. Good wear resistant property can ensure the purity of grinding material. The grinding efficiency is 30 or 40 times than nomal grinding medium. And it improves the service life basicly.
Application: grinding, bearings.
