Refractory, alumina ball, refractory ball, refractory balls, alumina balls, grinding balls, thermal storage balls, mullite balls, ball, balls, fire brick, refractories, refractory material, refractory products, alumina ball, grinding balls, alumina grinding ball, balls, ceramic ball
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
