China Alumina Ceramic Grinding Ball Ceramic Ball

Alumina balls are made from good quality and high temperature alumina powder. It is used for polishing of metal parts and grinding for non-metallic mineral powderUniversal Medical Implement (for instance zirconiDiamond Tools um silicate, kaolin and so on). It applies to all types of grinding and polishing machine. It is the grinding media for ball mill, pot mill, vibration mill and other fine powder grinding equipment, its grinding and wear resistance efficiency is much better than normal ballSound Module s and nature stones. They have characters of high purity, high strength, high hardness, more white, low abrasion, high temperature resistance, acid and alkali resistance, corrosion resistance.Performance IndexItem/Product75
