Alumina Grinding Ball
Alumina Ceramic Ball
Calcined alumina of high-temperature and low sodium is used as raw materials, following large-tonnage ball mill grinding, centrifugal granulation, and dry powder CIP, Rolling. The density has been improved with equal density and ball roundness. Excellent wear resistant property can ensure the purity of grinded material, whose grinding efficiency is 30 or 40 times than normal grinding medium.
