Abstract
The invention discloses a cement preparation method and relates to the field of construction production. According to the method, recycled marble is used for replacing limestone so as to prepare cement at a low temperature. The method comprises the following steps: processing the marble, gypsum and kaolin into fine powder; separately calcining in a high-temperature furnace; finally, evenly mixing. Cost is saved greatly by utilizing the method, which conforms to the current slogans and calling very well.
Description
Technical field
The present invention relates to architecture production field, be specifically related to a kind of method that cement is made.
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 200880118466.4 patent discloses a kind of method that cement is made, although play fixing effect, the high cost such as base mateiral water cement, carbon fiber of interpolation, uneconomical.
Summary of the invention
The object of this invention is to provide a kind of method that cement is made, 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 method that cement is made, is characterized in that:
(1) marble that sampling is returned replaces Wingdale low temperature to prepare cement;
(2) marble, gypsum and kaolin are made to fine powder, three is put into mill and grind to form careful grinding, become finely powdered;
(3) marble, gypsum and kaolin are calcined respectively through High Temperature Furnaces Heating Apparatus, finally mixed according to the ratio of three 5:3:2.
Preferably, described calcining high temperature should be controlled at 700-900 DEG C.
Preferably, after described marble, gypsum and kaolin calcined completing, should continue to be incubated 1-2h.
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 marble of coming, greatly having saved cost is on the one hand, also solved on the other hand discarded marble 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 marble that method (1) sampling that a kind of cement is made is returned replaces Wingdale low temperature to prepare cement; Marble can extensively reclaim and come from various construction sites and gangue materials factory.
(2) marble, gypsum and kaolin are made to fine powder, three is put into mill and grind to form careful grinding, become finely powdered; First the marble 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) marble, 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 mix according to the ratio of three 5:3:2.
Need to remind, described calcining high temperature should be controlled at 700-900 DEG C, and it is that marble, gypsum and kaolin all need grinding powder that this intersegmental temperature is applicable to three's calcining, then marble dust is placed in to High Temperature Furnaces Heating Apparatus, and temperature is controlled at 900-950 DEG C, insulation 1h.
Same, separately the powder of gypsum being placed in to High Temperature Furnaces Heating Apparatus again, temperature is adjusted between 800-900 DEG C, also needs to be incubated 40-50 minute, finally kaolin powder is put in to calcining in High Temperature Furnaces Heating Apparatus and, between 740-760 DEG C, is then incubated general 40-60 minute.
After described marble, gypsum and kaolin calcined completing, should continue to be incubated 1-2h, because after just calcining has been got well, marble, gypsum and also less stable of kaolinic character, again with soak for some time, until just can mix after stable in properties, 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.
Claims (3)
1. the method that cement is made, is characterized in that:
