90 High Alumina Ball
Yamtop is a leading manufacturer and supplier of high-quality high alumina balls. Our 90 High Alumina Ball and 99 High Alumina Ball products are designed to meet the needs of various industries, including ceramics, refractories, and petrochemicals.
Our 90 High Alumina Ball is made from high-quality bauxite and other raw materials with advanced processing technology. It has a high density, excellent wear resistance, and is widely used as a grinding media in ball mills and other applications.
Our 99 High Alumina Ball is made from 99% alumina powder with advanced processing technology, making it ideal for high-temperature applications. It has excellent thermal stability, high mechanical strength, and is widely used in the petrochemical, metallurgical, and electrical industries.
| Property | 90 High Alumina Ball | 99 High Alumina Ball |
|---|---|---|
| Alumina content (%) | ≥90 | ≥99 |
| Density (g/cm³) | ≥3.5 | ≥3.8 |
| Water absorption (%) | ≤0.02 | ≤0.01 |
| Crushing strength (N) | ≥2000 | ≥2500 |
| Thermal expansion (10⁻⁶/K) | 6-7.5 | 6.5-8.0 |
| Thermal conductivity (W/m·K) | 20-25 | 28-35 |
| Mohs hardness | ≥8 | ≥9 |
| Maximum operating temperature (℃) | 1400-1500 | 1600-1800 |
| Chemical stability | Resistant to acids, alkalis, and organic solvents | Resistant to acids, alkalis, and organic solvents |
| Applications | Grinding media in ball mills, wear-resistant components, catalyst support, etc. | High-temperature applications, such as furnace lining, refractory material, etc. |
As can be seen from the table above, both 90 High Alumina Ball and 99 High Alumina Ball have excellent physical and chemical properties, but they differ in their alumina content, density, and water absorption. 99 High Alumina Ball has a higher alumina content and density, as well as a lower water absorption, making it more suitable for high-temperature applications that require excellent wear and thermal shock resistance.
Overall, both 90 High Alumina Ball and 99 High Alumina Ball are high-quality products that offer excellent performance in various high-temperature applications. Depending on the specific needs of your application, you can choose the appropriate product that meets your requirements.
