Medium alumina grinding ball D30mm, D40mm, D50mm, D60mm
Medium alumina grinding ball produced by isostatic machines and sintered in high temperature tunnel kiln. Its wear resistance is increased 20-40times and its grinding efficiency is increased 40-60% compared with natural stone ball and normal ceramic balls. Except that using medium alumina grinding ball will increase the working life of mill.
Characteristics of alumina grinding ball from us:
High density
High hardness
High temperature resistance
High pressure ability
Anti-alkali and sulfur corrosion
