Ceramic balls, also known as alumina balls, are highly efficient grinding media for attritors and ball mills. They are suitable for both dry and wet grinding in ball mills.
Alumina ball is a product formed by cold isostatic pressing of α-alumina and sintering at high temperature. It is used in dry and wet grinding to achieve high density and hardness.
