Description
Product description
Alumina grinding ball is a high hardness, high density, non-polluting abrasive, mainly made of alumina powder through sintering, crushing and screening processes, and can be used for grinding, mixing, polishing and other processing processes of granular materials.

Feature 
1. High hardness: Aluminum oxide grinding balls have extremely high hardness and wear resistance, can effectively maintain their shape and size, and improve grinding efficiency and precision.

2. High density: The density of alumina grinding balls is much higher than ordinary grinding balls, which can provide greater grinding force and better grinding effect.

3. No pollution: Due to the high purity of the material and processing process of the alumina grinding ball, it will not pollute the material and meet the requirements of environmental protection.

4. Good acid and alkali resistance: alumina grinding balls have high chemical stability and are not easily eroded and corroded by chemical substances such as acid and alkali, and are suitable for grinding various granular materials with different properties.

5. Long service life: Due to the high hardness and wear resistance of alumina grinding balls, the service life is longer than that of ordinary grinding balls, which can reduce the grinding cost.

The production method of alumina ball
Alumina powder is rolled with a ball machine, or sintered at high temperature after isostatic pressing.

Application
1. Used as a grinding and polishing material
Use alumina balls as polishing abrasive to avoid scratches
2 for the electronics industry
Due to the excellent properties of spherical alumina in electrical, thermal and mechanical properties, it is widely used in the field of semiconductor electronic packaging.
3 Glass grinding, first of all, the hardness of glass is very high, and the processing capacity of ordinary grinding media is limited. 
The mixing of excessive impurities will greatly reduce the quality of glass, resulting in poor quality of finished glass and inability to make high-quality products. Alumina grinding balls can solve this problem very well.
4 Timely grinding, the hardness is also very high, especially high white quartz has high requirements for whiteness, just the color of alumina is white, which solves the grinding problem of high white quartz from many aspects.
5 Lithium battery grinding is an emerging sunrise industry, and alumina grinding balls can show their powerful strength through their own materials. We know that lithium battery materials are very sensitive to iron, so metal grinding cannot be used inside. Non-metallic grinding media, alumina grinding balls have high efficiency, so they become ideal grinding materials.
