The literature standardizes the zirconium silicate grinding media in terms of terminology, definitions, technical requirements, test methods, inspection procedures, mark, package, transportation and storage, etc. The standard is applicable to grinding media ball between 0.5-15mm with zirconium silicate content above 60%. This standard unifies detailed test method of zirconium silicate grinding media ball, especially in aspects of wear rate, roundness and hardness. The standard also fills a gap in the industries where zirconium silicate grinding ball is commonly applied.
