In order to solve the above technical problems, one aspect of the present invention is：Provide one kind and be suitable for high temperature and be total to
The preparation technology of the alumina ceramic prilling powder of burning, carried out using non-aqueous solvent and the binding agent to be mixed with it to modulate slurry
It is granulated, including step in detail below：
A, dispensing, alumina powder and sintering aid are added in ball milling bucket, then add non-aqueous solvent and bonding
Agent；
B, ball milling slurry, ball milling 20 hours is carried out by ball milling bucket is closed；
C, slurry agitation, the good slurry of ball milling is added in closed agitator and carries out slurry agitation；
D, granulation powder, the atomizer comminutor progress powder that the above-mentioned slurry being stirred is poured into totally-enclosed are done
It is dry, obtain granulation powder；
E, sieving iron removaling, dried granulation powder sieving iron removaling is standby.
In a preferred embodiment of the present invention, described solvent uses alcohol, and binding agent uses PVB.
In a preferred embodiment of the present invention, the atomizer comminutor of described totally-enclosed is using the special of totally-enclosed
Door is used for the atomizer comminutor that spirit solvent is granulated.
