alumina grinding ball
Wear-resisting alumina ball is high quality grinding media,which use selected high quality materials,advanced cold isostatic pressing forming technology and made after high calcined temperature.In order to meet the domestic and foreign customers for different class product demand,besides the 92% alumina grinding ball,we develop other different grades of products.
