Background technique
Currently, the flouring technology of architectural pottery mainly includes spray drying wet powder-making technique and dry method flouring technology two
Kind.
It is spray-dried the preparation that wet powder-making technology is applied to the dry-pressing formed powder of ceramic wall and floor bricks, the powder of preparation
Material can meet the requirement of the automatic brick machine of large-tonnage, produce high quality, high-grade product.It is spray-dried the excellent of wet processing
Point is recognized by everybody.However, the technique is about 35% through adding the resulting slurry moisture content of water for ball milling, it is granulated after spray-dried
At the powder of moisture content about 7%, therefore about 28% moisture content need to be dried and gone up in energy prices today there are the high deficiency of energy consumption
And seem further prominent in Wall or floor tile market competition.
Fine powder is made through Vertical Mill or Raymond mill for raw material in the technical process of dry method powder, and moisture content is about 2%, is then passed through
Pelletizer adds water to be granulated, and moisture content is about 12% after granulation, and aqueous 7% or so powder is made after dry using liquefaction.State at present
Though powder particles prepared by the non-slurry pelletizing machine equipment of inside and outside exploitation are able to satisfy the production requirement of automatic brick machine, the inherent matter of brick
Amount also can reach national product quality standard, but with wet processing powder powder ratio, powder is still more in lower fine powder, powder flowing
Property poor, the disadvantages of powder intensity is bad, and conveying is inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of architectural pottery wet-dry change flouring technologies to be adopted based on the requirement of pelletizer moisture content

Second.
Further, soft material is crossed 14 meshes and is carried out except Slag treatment in the wet process slurrying, and slurry is aqueous after slurrying
Rate be 35 ~ 45%, flow velocity 30-60 seconds.
Further, each raw material total moisture content < 12% when the feedstock of the dry method powder.
Further, the iron mode of removing of the dry method powder is that bar magnet removes iron.
Further, dry powder moisture content made from the dry method powder is 1-4%.
Further, it is 13-14% that the dry granulating machine, which is granulated powder moisture content obtained,.
Further, powder moisture content obtained is 6-8% after the dry and wet legal system powder fluidized drying.
Further, powder particles gradation made from the dry and wet legal system powder pelletizer are as follows: 20 mesh: < 1%；30 mesh: 2 ~ 5%；
40 mesh: 10-15%；60 mesh 10-15%；80 mesh: 20-30%；100 mesh: 20-30%；120 mesh 10-20%；Below 200 mesh: < 15%.
Further, the aging time of the dry and wet legal system powder is 3-5 days.
The beneficial effects of the present invention are: the requirement based on pelletizer moisture content, using dry method powder and wet process continuous ball milling phase
In conjunction with flouring technology, matched by reasonable slurry, make be granulated after moisture content 13-14%, compare wet powder-making energy consumption is high
Amplitude reduction.Simultaneously by whitewashing atomization granulating working procedure in wet-dry change pulverizing process, slurry viscosity is good, the powder intensity produced
Height, fine grained is few, powder good fluidity, is conducive to the transport and forming of powder.
Compared to wet powder-making technique, the wet-dry change flouring technology of the application is also had the advantages that
(1) about 60% is saved water:
The moisture content of ball mill by wet process slurry is 35% or so, and traditional spray prilling process needs the material moisture content 35%
Slurry is dried to the pellet of 7% moisture content, and drying course need to dry about 28% moisture, and it is about 0.5m that powder, which prepares water consume,3/ t powder
Material.And after the wet-dry change of the application carries out non-slurry pelletizing in the ratio 1:3 ~ 5 of wet feed and siccative, moisture content 13-14%, fluidisation
Bed only needs the dry finished product material to 7% moisture content of material moisture content 13-14%, and drying course need to only dry the water of 6-7%
Point, it is about 0.2m that powder, which prepares water consume,3/ t powder, water-saving rate are about 60%.
(2) energy saving about 70%:
Since the process procedure of dry and wet legal system powder reduces about 21-22% than the drying amount of the granulation drying moisture of wet powder-making technique,
And traditional spray prilling powder preparation energy consumption is about 55~60kg mark coal/t powder, the wet-dry change powder preparation of the application
Energy consumption is about 16.5-18kg mark coal/t powder, the energy consumption of saving about 70%.
(3) pernicious gas and dust emission are reduced:
Because the moisture of evaporation is about the one third of conventional wet, required fuel is few for wet-dry change production, the flue gas row that fuel generates
Total amount is put less than wet production, desulphurization denitration treating capacity is small, and conventional wet flouring technology has to carry out desulphurization denitration processing
Emission request is got to, a large amount of man power and material of consumption need to be surpassed.The wet-dry change flouring technology of the application can subtract by a relatively large margin
Few SO2The discharge of equal harmful pollutants and dust.
Detailed description of the invention
Fig. 1 is architectural pottery wet-dry change flouring technology flow chart.
Specific embodiment
In order to which the technical problems, technical solutions and beneficial effects solved by the present invention is more clearly understood, below in conjunction with
Process flow chart and embodiment, the present invention is further illustrated.
