Detailed information:

The alumina ceramic grinding balls used for grinding is a high-strength, high hardness, wear-resistant, and corrosion-resistant ceramic material. This spherical material has excellent physical and mechanical properties and is commonly used in the industrial fields of grinding and abrasive processing.

Alumina ceramic grinding balls have high hardness and can be used for grinding and processing wear-resistant materials. Secondly, compared to metal grinding media, after slight wear, the surface of alumina ceramic balls can quickly form a passivation layer, reducing chemical pollution and impact on the processed materials. Due to the low density of alumina ceramic balls, they become a very lightweight grinding medium.

Different applications:

Ceramic Industry

Cement Industry

Product features and advantages:

1. High hardness: The alumina ceramic grinding balls have a hardness of up to 9 Mohs. Which is more than 5 times higher than ordinary steel balls. It has strong wear resistance and corrosion resistance, greatly extending its service life.

2. Lightweight and high-strength: 92% aluminum balls have a light specific gravity and a density of 3.6-3.67g/cm ³ About 1/3 lighter than steel balls, making it easy to handle and process. In addition, its high strength is also one of its advantages, with a compressive strength of over 2000MPa.

3. Good stability: aluminum grinding balls have relatively stable chemical properties and are not damaged by high temperatures, acids, and alkalis, and will not cause secondary pollution to the treated materials.

4. Good high-temperature resistance and thermal conductivity: ceramic aluminum balls have a high melting point and thermal expansion coefficient, and will not deform even after long-term use at high temperatures. At the same time, they have good thermal conductivity.

5. Good compressive performance: aluminum grinding balls have excellent compressive performance and can maintain their shape even under extremely high pressure.
