The alumina grinding ball is the grinding body in the crushing equipments
such as mill machine, pot mill machine, vibrating mill machines. It has
such features as high hardness, large density, high anti-acid rate and low abrasion rate so that its
crushing efficiency is much higher than common ball
and natural cobblestone. This product is mainly used in the ceramic, glass, porcelain, pigment and
chemistry industries.
