Abstract
The invention discloses a production method of high-efficiency cement, relating to the field of building production. According to the method, shells are used instead of limestone as the substrate to fire the cement. The method comprises the following steps: making the shells, gypsum and kaolin into fine powder, respectively calcining in a high-temperature furnace in a ratio of 4:3:3, and finally, uniformly mixing. The method is economical and practical; and since the amount of the shells is not limited, the shells can be taken freely, thereby saving abundant cost.
Description
Technical field
The present invention relates to architecture production field, be specifically related to a kind of production method of high-efficiency cement.
Background technology
Cement, powdery hydraulicity inorganic coagulation material, in recent years, because investment in fixed assets increases, the fast development of infrastructure construction, real estate was fairly obvious to the pulling function of cement output.Under huge demand pull, cement output will keep comparatively stable growth, and people are also to increase year by year for the demand of cement.Application number is that 200710137472.1 patent discloses a kind of production method of high-efficiency cement, although improved the effect of cement, the manufacture craft of cement is not changed, and the base mateiral of its interpolation does not change, and high cost is uneconomical.
Summary of the invention
The production method that the object of this invention is to provide a kind of high-efficiency cement, to solve the technological deficiency in cause in prior art above-mentioned.
Technical problem solved by the invention can realize by the following technical solutions: a kind of production method of high-efficiency cement, is characterized in that:
(1) shell that sampling is returned replaces Wingdale low temperature to prepare cement;
(2) shell, gypsum and kaolin are made to fine powder, three is put into mill and grind to form careful grinding, become finely powdered;
(3) shell, gypsum and kaolin are calcined respectively through High Temperature Furnaces Heating Apparatus, finally according to the ratio of three 4:3:3, mixed.
Preferably, in described cement, can add ethylene glycol, sodium acetate, sodium carbonate and calcium chloride, ratio is respectively 10-40%, 10-20%, 10-20%, 10-30%.
Preferably, after described shell, gypsum and kaolin calcined completing, in cold water, be cooled to after room temperature, at grind into powder through the screening of sifting out.
The invention has the advantages that: making method, more traditional and uncomplicated also slightly simple, the ubiquity of most importantly making material has improved practicality of the present invention greatly, because replace Wingdale with reclaiming the shell of coming, greatly having saved cost is on the one hand, also solved on the other hand discarded shell and processed a difficult problem, played material and recycled effect, turned waste into wealth.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
The shell that a kind of production method of high-efficiency cement (1) sampling is returned replaces Wingdale low temperature to prepare cement; Shell can extensively reclaim and come from various construction sites and gangue materials factory.
(2) shell, gypsum and kaolin are made to fine powder, three is put into mill and grind to form careful grinding, become finely powdered; First the shell of bulk, gypsum and kaolin etc. can be put into rubble agitator, stir into little microlith piece,, moreover, three's little thin piece is added in stone mill, grind to form finely powdered.
(3) shell, gypsum and kaolin are put into High Temperature Furnaces Heating Apparatus, to High Temperature Furnaces Heating Apparatus heating, after furnace temperature is elevated to suitable temp, three is being calcined respectively, after calcining finishes, finally according to the ratio of three 4:3:3, mix.
What need prompting is, in described cement, can add ethylene glycol, sodium acetate, sodium carbonate and calcium chloride as the additive of cement, improve the performance of the each side of cement, ratio is respectively ethylene glycol 10-40%, sodium acetate 10-20%, sodium carbonate 10-20%, calcium chloride 10-30%, in original cement formula, mixture is 15%, adds grog and additive through grinding the cement of making, and the ultimate compression strength of this cement has improved greatly.
The cement that does not add additive and compound with original cement clinker under similarity condition is compared 3t and has been improved 3MPa, and by cost-saving 6.4 yuan per ton, the cement mill of producing 100000 tons per year can increase by 640,000 yuan of profits every year.
After described shell, gypsum and kaolin calcined completing, should continue to be incubated 1-2h, because after just calcining has been got well, shell, gypsum and kaolinic character is less stable also, then with soak for some time, until just can mix after stable in properties, insulation for some time after mixing, after being placed in cold water cool to room temperature, taking out also fragmentation and be ground to finely powdered, the sieve screening that is 0.08mm through sieve aperture again, so just can form required cement.
More than show and described ultimate principle and principal character and the advantage of the present invention of invention.Described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
