Grinding ball is used in a ball mill mill media used to crush the mill material, one is, the main alloying elements of chromium white cast iron referred to as chrome cast iron, chromium alloy Cast iron cast iron balls as the material is called chrome cast iron grinding ball; the other is to cast iron nodular cast iron ball is called the ductile iron ball, which obtained by heat treatment of the matrix is mainly bainite nodular Cast iron grinding ball referred to as bainite ductile iron ball; obtained by heat treatment of the matrix is mainly martensitic ductile iron grinding ball referred to as martensitic ductile iron ball.
Grinding ball is widely used in metallurgy and mining, cement building materials, thermal power generation, flue gas desulfurization, magnetic materials, chemicals, coal water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand and other industries ball mill .
