Detailed information of alumina grinding balls:
Microcrystalline Wear Resistant Alumina Grinding Ball processed with high density, high harness, low wear loss, good seismic stablity and good corrosion resistance. The alumina balls are the most ideal grinding medium for grinding glaze, blank and mineral powder processing. Used as the grinding media of ball mill in ceramics, cement, paint, refractory, inorganic mineral powder and other industries. It's possible to make the ballstone in different specifications as customers' requirements.

Why Choose Us
1. Wear Resistance
Engineered with a dense microcrystalline structure, our alumina grinding balls deliver exceptional wear resistance, ensuring prolonged service life even under extreme grinding conditions. Reduce downtime and replacement costs significantly.
2. High Hardness & Strength
With a Mohs hardness of ≥9 and superior fracture toughness, these grinding balls maintain their shape and integrity under high-impact loads, minimizing breakage and contamination in your grinding process.
3. Precision Performance for Fine Grinding
The microcrystalline alumina matrix ensures uniform particle size distribution and ultra-smooth surfaces, achieving finer grinding results for industries like ceramics, electronics, and advanced materials.
4. Corrosion & Chemical Resistance
Ideal for harsh environments, our alumina balls resist acids, alkalis, and solvents, making them perfect for chemical, mining, and pigment industries.
Delivery of alumina balls usually arranged by sea. For the packing, both Jumbo bags and 25kgs bags can be supported refer to customers' demand. Each 20' container can usually load 20-27tons alumina balls, it may depend on the limit by differnt countries.
Production process:
Firstly, we use high purity ultrafine α-alumina powder as the main raw material. Then grinding the minerals though ball mill. Use centrifugation or spray drying tower granulation, then alumina balls would be shaped through isostatic pressing of the dry bag method or the wet bag method. Finally, after burning in high tempurature tunnel kiln calcination, alumina balls are finished processing.
