Product Overview

High-alumina ceramic balls are premium grinding media offering the ideal combination of hardness, density and wear resistance for ball mills processing minerals, ceramics, paints and cement. The high Al₂O₃ content delivers a Mohs hardness of 9 and extremely low abrasion loss, reducing media consumption and product contamination.

Our 92% and 95% alumina grinding balls are pressed and fired to tight diameter tolerance, providing consistent charge behavior and superior milling efficiency in both wet and dry grinding circuits.
