Abstract

The invention discloses a cement production method. The method comprises the steps of material preparation and material mixing, wherein the step of material preparation comprises the procedures of washing, drying and levigating slag and screening the powder with a 130-180-mesh screen, thus obtaining slag ash A; pulverizing lime lumps and screening the lime powder obtained after pulverization with a 150-180-mesh screen, thus obtaining lime powder B; refining gypsum, screening the gypsum powder obtained after refining with a 120-160-mesh screen and heating the obtained screened particles at 120-155 DEG C for 5-10 minutes, thus obtaining gypsum powder C; the step of material mixing comprises the step of mixing 45-70% of A, 20-40% of B and 10-15% of C by weight uniformly. The method has the beneficial effects that the method is simple to operate; the raw materials are convenient to draw and are low in costs; the cement can be produced more simply in areas where finished cement is inconvenient to use, and plays a certain role in promoting energy conservation and emission reduction in China.

Description

A kind of method for production of cement
Technical field
The present invention relates to building trade materials proportioning and upper product field, particularly relate to a kind of method for production of cement.
Background technology
Cement, powdery hydraulicity inorganic coagulation material.Add water and stir rear one-tenth slurry, can in air, harden or better sclerosis in water, and can the material such as sand, stone is cemented together securely.Cement mono-word is developed by Latin caementum, is the meaning of rubble and slabstone.Early stage lime is very similar to modern lime pozzolanic cement to pozzuolanic mixture, the concrete made from its cementing rubble, and after sclerosis, not only intensity is higher, and can also resist the erosion of fresh water or brackish water.For a long time, it,, as a kind of important gelling material, is widely used in the engineerings such as civil construction, water conservancy, national defence.
Although cement production capacity surplus in prior art; in some remote mountain areas; often can run into the situation that mixed earth is little to less demanding, the required cement consumption of Cement Quality, finished cement is not easy to purchase and transport of cement is very inconvenient; if produce a kind of cement that meets construction requirement under condition at the construction field (site), will bring very big facility for improving construction speed and reducing construction cost.
Summary of the invention
For often running in above-mentioned prior art, mixed earth is little to less demanding, the required cement consumption of Cement Quality, the very problem of the situation of inconvenience of the transport of finished cement, the invention provides a kind of method for production of cement.
For addressing the above problem, a kind of method for production of cement provided by the invention achieves the goal by following technical essential: a kind of method for production of cement, comprise material preparation and material mixture ratio, described material is prepared to comprise by clean, dry, levigate slag ash, use 130 to 180 eye mesh screens screenings, is obtained slag ash A;
The lime powder obtaining after lime block efflorescence, efflorescence uses 150 to 180 eye mesh screen screenings, obtains lime powder B;
Terra alba after gypsum refinement, refinement uses 120 to 160 eye mesh screen screenings, the screening powder obtaining is heated to 5-10 minute at 120 to 155 DEG C of temperature, obtains terra alba C;
Described material mixture ratio comprises the shared gross weight proportion separately by above-mentioned A, B, C: 45-70%, 20-40%, 10-15% evenly mix.
The mixture that A, B, C are evenly mixed to get is cement, above slag ash, gypsum, lime block purchase cost method low, that can adopt hammer to strike to the pulverizing of slag ash, gypsum, lime block, obtaining slag ash A, terra alba B, gypsum powder is easy to realize, to gypsum powder, heating can adopt the method for iron pan frying, and above material is prepared, material mixture ratio does not all need professional equipment to be realized.
Further technical scheme is:
For the organic impurity and the sand that contain in the slag ash of place to go, improve the quality that finally obtains cement, need clean slag ash, for ease of implementing, described slag ash is cleaned and is adopted washing.
For obtaining the uniform lime powder B of exquisiteness and particle diameter, the lime block that described lime block efflorescence adopts is unslaked lime, and lime block efflorescence adopts water spray efflorescence processing.The reaction times that unslaked lime and water are processed in further described water spray efflorescence is not less than 4 hours.
Above step to mixture add water stir after coagulation slow, for improving this shortcoming, described material is prepared also to comprise saltcake piece is crushed to the saltcake powder C that particle diameter is 0.075-0.15mm, described material mixture ratio also comprises that saltcake powder C evenly mixes with A, B, C, and the proportion that saltcake powder C accounts for mixture total weight amount is 1-4%.
The present invention has following beneficial effect:
A kind of method for production of cement of the present invention is simple to operate, raw material be convenient to draw materials and cost low, the more general cement of cement finally obtaining, have a water resisting property, acid-alkali-corrosive-resisting is good, strength mark is between 200-300, be applicable to the buildings that underground works and soda acid corrode, being not easy to use the area of finished cement comparatively simply to make, national energy-saving and emission-reduction are had to certain pushing effect.
