Alumina Ball Advantages
1) Alumina ball is one ideal ball mill grinding media, it can keep the purity and improve the stability of grinded materials.
2) Alumina ball has been widely used in ball mills as abrasive media for ceramic raw materials and glaze materials in ceramic factories, cement factories, enamel factories and glasswork.
3) The main features are high density, high hardness and strength, high wear resistance, thermal stability, corrosion resistance and non-pollution etc.
4) During the abrasive/grinding processes, ceramic balls will not be broken, it will not contaminate the materials to be grinded.
5) Type: According to the content of aluminum oxide: 60-70%, 65-75%, 92%, 95%
Product Qualifications
1. Chemical composition certification
Al2O3 content: Clearly marked alumina content (such as 92%, 75%, 60%, etc.) to ensure compliance with industry standards.
Impurity control: Detect and control impurity content (such as SiO2, Fe2O3, etc.) to ensure product purity.
2. Physical performance authentication
Hardness: Pass the Mohs Hardness or Vickers Hardness test to ensure wear resistance.
Density: Bulk Density is measured to ensure compliance with specifications (e.g., ≥3.15 g/cm³).
Compressive strength: Test compressive strength to ensure that it is not easy to break under high pressure environments.
3. Wear resistance test
Wear resistance tests are carried out by professional equipment such as ball mills to ensure low losses during prolonged grinding.
4. Dimensional accuracy
The size range (such as 0.5mm-60mm) must meet customer requirements and ensure dimensional consistency through testing.
5. Corrosion resistance test
Test the stability of products in corrosive environments such as acid and alkali to ensure that they are suitable for chemical industry.
