Introduction:
It is used as the covering, packing and supporting materials of the catalyst in reactors and columns in varied areas.it broadly utilized in petroleum, chemical industry, chemical fertilizer, natural gas, and environmental protection fields etc.Based on the Alumina Balls, we developed series of 38 different kinds and size of them with different alumina contains, the porous balls, and ceramic columns.
Advantage:
1. strong resistance to the high temperature and high pressure,
2. lower ratio of the moisture absorption, stable chemical properties,
3. High wear-resistance
The alumina balls wear-resistance is higher than the common alumina balls. When it is working, the ball wont pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.
4. High density
The high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
