Alumina ceramic balls are a key functional material in industrial grinding, catalytic reactions, and material filling. Balls with varying alumina contents (e.g., 92%, 95%, and 99%) vary significantly in performance, application scenarios, and cost. Choosing the right ball model can significantly improve production efficiency and reduce operating costs.
