Characteristics of alumina ceramic grinding balls and four common grinding applications

Alumina ceramic grinding balls are made of high-purity alumina powder rolled by a ball forming machine or isostatically pressed and then sintered at high temperature. The density of 92 alumina balls is about 3.6, the Mohs hardness is 9, and the water absorption is about 0.01. %, the self-wear amount is 0.01. Because of the above characteristics, alumina ceramic grinding balls are widely used in the following four grinding applications:

Let me first talk about the application of alumina ceramic grinding balls in quartz grinding.

The hardness of quartz is also very high, especially high white quartz with high whiteness requirements. The color of alumina is also very white, which solves the problem from many aspects. The grinding problem of white quartz can reduce the pollution of quartz during grinding.

In addition, understand the grinding of alumina ceramic grinding balls in glass.

The hardness of the glass is very high. The processing ability of ordinary grinding media is limited. Excessive impurities will greatly reduce the quality of the glass, resulting in poor quality of the finished glass, which cannot be produced. Produce high-quality products. Alumina grinding balls can solve this problem well.

There is also high alumina ceramic grinding balls that can be used in lithium battery grinding.

This is an emerging industry. Alumina ceramic grinding balls can show their charm through their own materials. We know that lithium battery materials are very sensitive to iron, so metal Grinding combination is indeed unavailable, but among the non-metallic grinding media, alumina ceramic grinding balls have the highest efficiency, so it has become a very good substitute for grinding materials.

The last is the grinding in cement grinding, which is familiar to everyone.

Now the ceramics industry has developed into a more popular industry in recent years. Alumina ceramic grinding balls have the characteristics of extremely low wear, thermal conductivity and low density. So it has good performance in the two-stage water mill. Especially in energy saving and consumption reduction, the effect of improving product quality is more obvious.
