Alumina Ceramic Grinding Balls

Alumina ceramic grinding ball is a grinding media made from aluminum oxide powder through dosing, grinding, powder manufacturing, taking shape, drying, sintering, etc. The appearance is a white ball with a diameter ranging from 0.5mm to 120mm. According to the different content of alumina, alumina ceramic grinding balls can be divided into medium alumina balls, upper medium alumina balls and high alumina balls. In general, we classify 60%.

Alumina ceramic grinding ball is a grinding media made from aluminum oxide powder through dosing, grinding, powder manufacturing, taking shape, drying, sintering, etc. The appearance is a white ball with a diameter ranging from 0.5mm to 120mm. According to the different content of alumina, alumina ceramic grinding balls can be divided into medium alumina balls, upper medium alumina balls and high alumina balls. In general, we classify 60%-65% Al₂O₃ content as medium alumina balls, 75%-80% Al₂O₃ content as upper medium alumina balls, and above 90% as high alumina balls.

Alumina ceramic grinding balls choose high quality alumina as basic material which is higher in purity, less in impurity and steadier in quality. In addition, we carry out strict quality control and the whole production process can be controlled and tracked back in order to ensure the stability of quality.

Products Advantages:

1. The main ingredient of alumina ball is superior alumina with high whiteness, which has no influence on the quality of the material to be ground.

2. The products are shaped by rolling and isostatic pressing, which has a significant ratio and can greatly improve the grinding efficiency, reduce the grinding time, and effectively increase the effective volume of the ball mill so as to increase the adding quantity of materials to be ground.

3. The product has low abrasion and can greatly extend the service life of the grinding body

4. the product can withstand more than 1000 degrees of high temperature as well as acid, alkali resistance, corrosion resistance.

 

Products Application:

The alumina ceramic grinding balls are mainly used as grinding media for ball mill in ceramics, mining, cement, paint, chemical, coating, refractory and other industries.
