In the production process of alumina ceramics, in the process of dry pressing or isostatic pressing, it is necessary to form a granular powder by spray drying of the ceramic slurry. It is required to have good fluidity and certain strength of the particles. In the process of transportation and feeding, it is not broken, and there is a certain particle level ratio. When feeding, it is closely packed, has certain bonding characteristics and lubrication characteristics, and should not be bonded to each other.
