Two, after block aluminium oxide ceramics green compact feed back step one collected is broken into powder, collect with step one
To powdered alumina ceramic green feed back sieve together, except part ferrum；
Three, step 2 is processed addition dispersant, water and abrading-ball in the feed back obtained and carries out first stage ball milling, after completing
It is added thereto to binding agent again and carries out second stage ball milling, after ball milling terminates, obtain slurry, then, sieve, then except a part
Ferrum；Wherein, the mass ratio of described feed back, abrading-ball and water is 1: (2-3): (0.5-1.5)；The consumption of described dispersant is feed back matter
The 0.5-0.8% of amount；The consumption of water is the 2-5% that consumption is feed back quality of binding agent；
Four, step 3 is processed the slurry obtained to be stirred, then, mist projection granulating, obtain pelletizing, it is right i.e. to complete
The process of aluminium oxide ceramics green compact feed back.
The first stage Ball-milling Time of described step 3 is 10-24h；Second stage Ball-milling Time is 0.3-1h.
Dispersant in described step 3 is PAA-Na, binding agent be mass fraction be the polyvinyl alcohol water solution of 1-5%.
The mixing time of described step 5 is 4-6h.
During material is made in the spraying of described step 5, inlet temperature is 190-220 DEG C, and leaving air temp is 105-115 DEG C.
Advantages of the present invention: a kind of aluminium oxide ceramics green compact feed back processing method of the present invention, processes the aluminium oxide obtained
Pelletizing, performance is close with original pelletizing；Its pelletizing characteristic complies fully with cold isostatic compaction technology requirement, finally sinters
The product that the performance of goods is prepared close to former pelletizing, sintered；Achieve the recycling to aluminium oxide ceramics green compact feed back, improve
Utilization rate to resource, and, processing method low cost, efficiency is high, environmental protection.
Detailed description of the invention
In order to deepen the understanding of the present invention, being described in further detail the present invention below in conjunction with embodiment, this is real
Execute example and be only used for explaining the present invention, protection scope of the present invention is not constituted and limit.
