Dia. 30-40mm, formed by rolling method and isostatic pressure method. Dia. 30mm/40mm/50mm/60mm/70mm formed by isostatic pressure method. 5. Advantages: (1) Core technique: Using the global best alumina grinding ball producing technology oiginated from ou over 13 years woking experience as well as our frequent technique research. This core technique enable us to be produce high quality products continuously to satisfy the requirement of our global partners. (2) Production system and equipment: We are using high temperature tunnel kiln with temperature of 1650 centigrade to sinter the alumina poducts, which enable us to produce higher and more stable quality alumina ball. Due to the temperature difference of roller kiln is much smaller than that of tunnel kiln used by other manufacturers.
