ZhongXing has developed all kinds of Alumina Grinding Ceramic Ball to meet the home and abroad customer’s demand. In order to meet customer’s different requirement for the ceramic grinding media ball , we had developed High different series of grinding balls. Such as alumina grinding ceramic ball, middle alumina grinding ceramic ball(Micro-crystal medium-alumina, 65% to 75% alumina ), and high alumina grinding ceramic ball. ( 92% ,95% and 99% alumina ). ZhongXing Alumina Grinding Ceramic Ball also has the advantage of high wear resistance, high hardness, and good corrosion resistance.
Because of Alumina Grinding Ceramic Ball’s high density, high hardness and the high grinding characters for save the grinding time, enlarge the smashing room. And girding ball also won’t polute the grinded materials. So it can be a good abrasive media for improving the grinding efficiency. So our grinding ball widely used in glaze materials in ceramic factories and ball mills as abrasive media for ceramic raw materials.
