Ball Mill Grinding Media
Tecera's ball mill grinding media are high-purity alumina grinding balls. This ball mill grinding media delivers ultra-low wear loss. This ball mill grinding media boosts milling efficiency. This ball mill grinding media cuts downtime and product contamination.
Core Features & Benefits
Ultra-long service life with low wear: Formed via isostatic pressing and high-temperature sintering, our alumina ball mill grinding media reaches Mohs 9 hardness with a dense, uniform microstructure. Its 24-hour self-wear loss can be as low as 0.005%, 5–10 times more durable than steel balls or ordinary ceramic balls, greatly reducing replenishment frequency and unplanned shutdowns.
High grinding efficiency & energy saving: High bulk density provides stronger grinding impact, effectively improving powder fineness and production output while lowering unit energy consumption. The smooth, pore-free surface prevents material adhesion and maintains stable grinding performance.
Zero contamination for high-purity materials: Controlled high-purity formulation minimizes iron and impurity release during operation. For ceramic, lithium battery and fine chemical production, it eliminates product discoloration and purity degradation caused by grinding media wear, significantly reducing product reject rates.
Full size compatibility: Available in diameters from 0.5 mm to 80 mm, suitable for all types of ball mills, stirring mills and sand mills. Custom sizes and purity grades are available to match specific material hardness and process requirements.
