Ceramic Aluminum Grinding Media for Ink

Alumina grinding balls are used as grinding media in different industries. The raw materials are industrial alumina powder, bauxite, roller powder,, and high-temperature calcined Alpha alumina powder. Its production process includes batching, grinding, milling, forming, and drying , and sintering.The alumina balls are used in the fine grinding equipment like pot mills, ball mills,and vibration mills, etc. The grinding efficiency and wear resistance of alumina balls are much better than natural pebbles or ordinary ball stones. As per different alumina contents, it can be divided into medium aluminum balls, medium high aluminum balls and high aluminum balls.Generally, the balls with 60%-65% alumina content is classified as medium aluminum balls, the balls with 75%-80% alumina content is classified as medium-high aluminum balls, and the balls with more than 90% alumina content is classified as high aluminum balls. Aluminum grinding media can be used in ink production during the grinding process.
