As grinding media, this product is widely used in ceramic industry, paint industry, color industry, chemical industry, coating industry and mining industry. The advantages are: high hardness, good toughness, high density, good corrosion resistance, regular shape etc.We develop three series of grinding balls and lining bricks with high alumina balls series: 92% and 95% alumina; medium-alumina balls series: 65% 75% alumina and Carborundum grinding balls: 60% 70% alumina (also called brown medium alumina balls).
