Character of Microcrystal Wear Alumina Ball(CIP)
This product uses calcined alumina ceramics for high-temperature and low sodium as raw materials, large-tonnage ball mill grinding, centrifugal granulation, dry powder CIP shape, density uniform roundness...Good wear resistant property can ensure the purity of grinding material, which is 30 or 40 times than nomal spherulite. And it improves the service life basicly.
