1. Extrusion method
Extrusion forming of alumina ceramic ball is currently the same kind of ceramic ball in the lower grade, but also a large output of a forming method, generally used to form the following aluminum ceramic ball or clay ball.This kind of porcelain ball sintering temperature is low, the production equipment is simple, the investment is small, only needs the ball mill, the filter press, the vacuum mud machine, the lower temperature kiln can be produced.
2. Rolling method
Using the pellet method to form alumina porcelain ball is the production process of forming glutinous rice balls, which belongs to a semi-dry and wet forming method. It is formed by constantly sticking dry powder on the outside of the “wet core”.This kind of forming method determines the low density of the embryo body, and the stratification of the embryo body, which is easy to peel off during grinding and has poor impact resistance.The forming equipment is simple, only a set of granulator can be.
3. Hydraulic hard die
This forming method has higher requirements for powder, and powder is generally granulated by spray.Different equipment is used according to different specifications and production requirements. In the early stage of small batch production, hydraulic jacks were even used to form alumina porcelain balls. With the fierce competition in the industry, this production mode has been gradually eliminated.
4. Dry isostatic pressing forming alumina ball
Dry isostatic pressing of alumina porcelain ball is an advanced forming method at present, which is easy to realize automatic production and less affected by human factors. The consistency of shape and appearance of embryo body is better than that of wet bag cold isostatic pressing.
Alumina grinding ball has the characteristics of high hardness, high density, low abrasion, smooth surface, corrosion resistance, etc. It is the most ideal grinding medium for grinding glaze, billet and various powder materials.
