High-Quality Alumina Ceramic Grinding Ball for Ball Mills
Ceramic balls are manufactured from high-purity alumina materials, featuring excellent mechanical strength and superior wear resistance. Widely used in powder grinding and as packing support in reaction towers, they effectively improve grinding efficiency, reduce material contamination, and ensure the stability of catalyst beds with uniform gas-liquid distribution. Suitable for industries such as petrochemical, chemical, and battery materials.
Ceramic Alumina Grinding Ball
Ceramic alumina grinding balls are high-performance grinding media specifically engineered for fine powder processing. Made from high-purity alumina (92%, 95%, or 99% Al2O3) using isostatic pressing and high-temperature sintering, these balls exhibit exceptional density, hardness, and mechanical strength. They are widely used in ball mills, stirred mills, and vibratory mills as efficient media for crushing, dispersing, and refining solid materials.
Key Advantages:
High Hardness and Wear Resistance: Long service life with minimal wear, reducing the frequency of media replacement and lowering operational costs.
Excellent Chemical Stability: Chemically inert in acidic, alkaline, and solvent-rich environments, ensuring compatibility with a broad range of industrial applications.
Low Contamination: Virtually no leaching or impurity release during grinding, making it ideal for high-purity material processing such as advanced ceramics, battery materials, and pharmaceutical compounds.
High Grinding Efficiency: High bulk density and uniform size distribution enhance energy transfer efficiency and ensure rapid particle size reduction.
Applications include:
Electronic ceramics, magnetic materials, lithium battery cathode/anode materials, glass ceramics, pharmaceutical intermediates, inks, coatings, and nanomaterials-across industries that demand high-purity, high-precision grinding solutions.
