Compared with the method in the prior art, the method of the present invention has characteristics of energy saving, emission reducing, production energy consumption reducing, product quality improving, stable product performance, factory utilization rate of 100%, and reduction of the waste of mine resources.
Description
Technical field
The invention belongs to fire-resistant smelting applied technical field, be specifically related to a kind of bauxitic clay homogenization material and preparation method thereof.
Background technology
At present in electric power, petrochemical complex, fire-resistant smelting, the bauxite secondary homogenizing material that the aspects such as life use is because its aluminium content is lower mostly, (about 70%), and iron-holder is higher, (about 2.6%), volume density less (being 2.6) its product mainly all also exists that particle is uneven, and shape is bad, poor fluidity, insufficient strength, adsorptive power is not strong, can not meet the problem of need of production.
Summary of the invention
Object of the present invention is exactly for making up above deficiency, a kind of aluminium content provided is higher and stable, and iron-holder is lower, and volume density is high, shape of product can be made good, product performance are stablized, every physical and chemical index is higher than a kind of bauxitic clay homogenization material and preparation method thereof of national standard.
The present invention is achieved in that a kind of bauxitic clay homogenization material and preparation method thereof, its moiety by weight, bauxitic clay raw material 80-100 part, industrial Al
2o
3powder 0-20 part, proportioning raw materials also comprises bonding agent 0.1-0.2 part, agglutinant 1-2 part; Described bonding agent is polyvinyl alcohol, and described agglutinant is active alpha-Al
2o
3micro mist.
Described preparation method is by major ingredient low-grade bauxite and bauxitic clay waste material after high-temperature roasting, by deironing, increases aluminium, fragmentation, abrasive dust, shaping, burn till, the operation such as kiln discharge forms, roasting rear oxidation aluminium stable content is at 75-77%, and iron-holder is 0.5-1.5%, and volume density is 3.00.
By major ingredient bauxitic clay and the coarse crushing of bauxitic clay waste material, then wash mud and remove silt, adopt and manually choose removal of impurities, the wet grinding in ball mill again of bauxitic clay after silt will be gone, then classification, what separate roughly returns the circulation of Raymond mill and regrinds, fine granules is then by first step High gradient high intensity magnetic separator, select the mine tailing of titaniferous iron content, the one-level of ore pulp through arranging continuously of removing titaniferous iron content, the sorting of secondary fine ga(u)ge screen, the fines of choosing, the coarse fodder tailed over enters to regrind and then enters three grades and the sorting of level Four fine ga(u)ge screen, obtain fine granules, the siliceous mine tailing of removing compass screen surface, merge the fine granules sifted out at different levels, to make a gift to someone second stage High gradient high intensity magnetic separator, further removing titaniferous iron content
Mineral substance, then by flotation, the wet fine fodder obtained obtains highly purified bauxite ore through dewatering and filtering and to wet fine fodder.
The fine fodder that wet by bauxite ore is made ball or is pressed into that block carries out calcining in calcining kiln, obtains ripe fine fodder, ripe fine fodder is carried out cooling and forms.
A kind of bauxitic clay homogenization material of the present invention and preparation method thereof, has energy-saving and emission-reduction, and reduce production energy consumption, improve the quality of products, product performance are stablized, and producer's rate of utilization reaches the advantage of 100% reduction mine resources waste.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail,
A kind of bauxitic clay homogenization material, its moiety by weight, 85 parts, bauxitic clay raw material, industrial Al
