        Application: 1)Use in high speed stirred grinding mills in mining applications.  2)Ball mills as abrasive media for ceramic raw materials  3)Glaze materials in ceramic factories, cement factories, enamel factories  4)Glass work owing to the excellence of high density, high hardness, and high wear rate.   during the abrasive/grinding processing, ceramic balls will not break up; it will not pollute the grinded material as well. 5)The mix and crush procedure of ceramics, glass, glaze and frits, chemical and plastic industries.
