Description
Our alumina grinding ceramic ball been widely used in ball mills as abrasive media for ceramic raw materials and glaze materials in ceramic factories, cement factories, enamel factories and glass work.
During the grinding processing, ceramic balls will not been broken, it will not pollute the material to be grinded.
Available size: diameter2-3mm, diameter4-5mm, diameter8-10mm, diameter20mm, diameter25mm, diameter30mm, diameter40mm, diameter50mm, diameter60mm, diameter70mm.
