Yttria Stabilized ZrO2 Ceramic Spherical Grinding Ball 2.8-3.0mm

Zirconia grinding media show high crushing strength and fracture durability, leading to higher wear resistance, superior grinding efficiency and longer working life. Moreover, these grinding media are resistant to rust and corrosion, so it will not take pollution to the materials which are ground or dispersed. Nowadays, Zirconia grinding media have been widely applied in fine grinding plants as abrasive media for ceramic raw materials and glaze materials in ceramic, cement, glass, porcelain enamel, paints, pigments, chemicals, pharmaceuticals, paint industry, inks, cosmetics, inorganic mineral powders, fine chemical, coal-chemical, fertilizer, natural gas and environmental protection industries etc. Among various grinding media, Zirconia grinding media is a perfect choice which will help users improve product quality and effeciency.
