Application of alumina ball

In the grinding industry, alumina balls have won a wide market with their high hardness and high cost performance. Alumina balls are also widely used in the manufacture of luminescent materials, semiconductor electronic packaging, lithium batteries, catalysts, grinding and polishing, ceramic materials, cement powder, etc.

1. Quartz powder:

Since its color is very white and the quartz powder is also white, it will not pollute the quartz powder during the grinding process. The hardness of quartz powder is relatively high, so alumina balls with relatively high hardness are required for grinding.

2. Glass

Grinding glass powder also requires high-hardness alumina balls. High-hardness alumina balls produce less impurities when grinding glass, which can improve the quality of glass.

3. Positive and negative electrodes of lithium battery

Lithium batteries have the characteristics of high voltage and high capacity. Just like a chip, there can be more structures in the same space, which can improve the power of a lithium battery, and both the positive and negative materials have alumina balls to participate in grinding.

4. Cement powder

Grinding cement powder requires abrasives with low density, thermal conductivity and low wear. Alumina balls have this characteristic. The use of alumina balls can greatly improve the quality of cement powder.
