Description
Technical field
The present invention is specifically related to the energy-conservation dry method flouring technology of a kind of architectural pottery.
Background technology
The automatic production line of existing architectural pottery, especially ceramic wall and floor bricks, so long as use the producer of great tonnage press compression moulding, employed powder all prepares with wet processing.Be after raw material enters factory,, simultaneously, add 30%～40% water, carry out 10～18 hours grinding then being delivered into ball mill after the various raw material weighing.After meeting the requirements of fineness, put into suction pit, pass through the spray-drying tower mist projection granulating again, process needed powder at last.
This technology has two main aspects to have the phenomenon that energy consumption is big and waste.The one, ball mill is relatively wasted electric energy.Because several kinds of raw materials in the body recipe; Their grindability can have very large difference; The soft material that grinds easily can meet the requirements of fineness within by two hours, the hard material then needs several times even longer milling time just can meet the requirements of fineness.Just there was the grinding phenomenon in this.The 2nd, spray-drying tower need evaporate the most of water in the mud of moisture 30%--40% when mist projection granulating, processes moisture at 5%～7% qualified powder at last.This process will consume a large amount of heat energy.And after waste gas after burning and the water vapour mixing emptying, also can cause pollution to a certain degree to surrounding environment.
Summary of the invention
The objective of the invention is to solve prior art wet powder-making technology and have the deficiency that energy consumption is big and waste, provide a kind of architectural pottery that can significantly cut down the consumption of energy energy-conservation dry method flouring technology.
The present invention adopts following technical scheme to realize:
Be the energy-conservation dry method flouring technology of a kind of architectural pottery, it is characterized in that comprising the following steps:
1) hard material in the body recipe and soft material are separated;
2) it is subsequent use to use the ball mill soft material that water content is high to be processed into moisture 40%～70% mud;
3) hard material that different water contents is low uses pulverizing mill to be processed into respectively and meets the requirements of fine powder, is delivered into feed bin separately;
4),,, become batch proportioning to mix with the hard material fine powder that processes by automatic material-dispensing system according to body recipe; Then the mud for preparing is carried out the powerful mixing granulation as moistening agent and the hard material fine powder that mixes in the mixing granulation machine, the weight percent of mud is 24%～28%, and the weight percent of hard material fine powder is 72%～76%;
5) after the granulation, screening and particle optimization, the influent stream bed dryer is dried to needed particulate state powder then, can use after old 24 hours.
As a preferred version of the present invention: hard material granularity＜40mm.
As a preferred version of the present invention: the moil fineness that soft material processes is controlled at 325 orders～400 orders, tails over 1%～3%.
As a preferred version of the present invention: the fine powder fineness that the hard material processes is controlled at 250 orders～325 orders, tails over 1%～8%.
As a preferred version of the present invention: the material powder water ratio after granulation and the particle optimization is 9～12%.
As a preferred version of the present invention: be controlled at 4%～7% through the dried material powder of fluid bed dryer water ratio, the material powder particles becomes normal distribution at 0.2mm～0.8mm, is the circular solids shape.
As a preferred version of the present invention: the hard material is feldspar, porcelain stone, green coke, ripe Jiao, talcum, high alumina sand, diopside, agalmatolite, Tangxian County soil, Hebei is native, Laiyang is native, a kind of or multiple combination arbitrarily among the Wen Zushi, green coke jewel, useless base, sandstone.
As a preferred version of the present invention: soft material is the combination of any or two kinds in black mud, the clay.
That the present invention has is energy-saving and cost-reducing, pollute little advantage.Use dry method powder process novel process of the present invention, can make the performance of made powder, like granule strength, indexs such as the flowability of powder are identical with the prepared powder of spray-drying tower basically.Can normally use building on the pottery production line of robotization.Use the present invention to make powder and can economize on electricity more than 30%, practice thrift heat energy more than 80%, the comprehensive energy consumption index can descend more than 60%.
