Alumina balls in China
With the development of ceramic industry in China, alumina ceramic ball is more and more widely used, The different methods and equipments for the production are used, Now let's have a look.
1, Extrusion forming
The extrusion forming to make alumina ceramic ball is the lowest level, but its production amount is the biggest. it is commonly used in making medium alumina ceramic balls or clay balls.This kind of ceramic ball require low sintering temperature, simple equipments, small investment.
2, Granule-method
Granuel method belongs to a half dry wet forming method, it is forming constantly after paste much powder. The forming method determines low density and layered. It is not possible for grinding application.
3, Hydraulic hard grinding molding
It is not geometric spherical, but cylindrical or spherical. With this forming method, it is usually used for small beads with bothway hydraulic machine.
4, Wet Isostatic pressing
With this method, the ceramic balll is high density and even size.
5, Dry isostatic pressing
Dry isostatic pressing forming alumina ceramic ball is currently the most advanced forming method. It is easy to realize automatic production and not affected by human factors. The shape and appearance were superior to ceramic balls by the wet isostatic pressing.
Customers could choose the method according to different application.
