Abstract
The invention discloses a highly active mineral powder formula including: 0.3-4.0% of gypsum; 0-40% of manganese slag; and balance of granulated blast furnace slag; the granulated blast furnace slag, the manganese slag and the gypsum are mixed in the following weight percentage ratio; a wide mouth material preparation bin is used, while shaking of the wide mouth material preparation bin, the granulated blast furnace slag, the manganese slag and the gypsum are added into a grinding machine for production of highly active mineral powder by vertical mill grinding technology. The highly active mineral powder formula can overcome the shortcomings of low activity, high preparation cost and poor stability and the like in the prior art, and has the advantages of realization of high activity, low preparation cost and good stability.
Description
Technical field
The present invention relates to cement processing technique field, particularly, relate to a kind of formula of high reactivity breeze.
Background technology
Current concrete market common practice uses S95 level breeze.Within 2012, the applicant's whole year production breeze mean value is A7:66.1%, A28:90.4%, by Standard S95 level breeze A7 >=75%, the requirement of A28 >=95% closely (A7 and A28 detects by breeze country inspecting standard the breeze 7 days and 28 days activity that draw).
Need on existing level basis, improve ore grinding powder active, make it meet S95 level breeze A7 >=75%, A28 >=95% requirement.
Realizing in process of the present invention, contriver to find in prior art at least to exist active low, preparation cost is high and poor stability etc.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of formula of high reactivity breeze, to realize, activity is high, preparation cost is low and the advantage of good stability.
For achieving the above object, the technical solution used in the present invention is: a kind of formula of high reactivity breeze, comprising:
(1) granulated blast-furnace slag, manganese slag and gypsum are pressed following weight percentage proportioning:
Gypsum: 0.3 ~ 4.0%;
Manganese slag: 0-40%;
Granulated blast-furnace slag: surplus;
(2) configure in proportion by granulated blast-furnace slag, gypsum and manganese slag, use wide mouth blanking bin, while wide mouth blanking bin is shaken, granulated blast-furnace slag, manganese slag and gypsum are added shredder, produce high reactivity breeze by vertical mill grinding technical matters.
Further, described gypsum is desulfurated plaster.
Further, SO in described desulfurated plaster
3content be 2.5 ~ 4.0%.
Further, the weight percentage of described manganese slag is 30-40%.
The formula of the high reactivity breeze of various embodiments of the present invention, owing to comprising: by granulated blast-furnace slag, manganese slag and gypsum by following weight percentage proportioning: gypsum: 0.3 ~ 4.0%; Manganese slag: 0-40%; Granulated blast-furnace slag: surplus; Configure in proportion by granulated blast-furnace slag, gypsum and manganese slag, use wide mouth blanking bin, while wide mouth blanking bin is shaken, granulated blast-furnace slag, manganese slag and gypsum are added shredder, produce high reactivity breeze by vertical mill grinding technical matters; Thus can to overcome in prior art active low, preparation cost is high and the defect of poor stability, with realize active high, preparation cost is low and the advantage of good stability.
Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from specification sheets, or understand by implementing the present invention.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.

Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, as Figure 1-Figure 4, provide a kind of formula of high reactivity breeze, comprising:
Step 1: by granulated blast-furnace slag, manganese slag and gypsum by following weight percentage proportioning:
Gypsum: 0.3 ~ 4.0%;
Manganese slag: 0-40%;
Granulated blast-furnace slag: surplus;
In step 1, gypsum content is preferably 3.5 ~ 4.0%, and gypsum optimum content is 4.0%; Gypsum is desulfurated plaster, SO in desulfurated plaster
3content be 2.5 ~ 4.0% (optimum content is 2.8%); The preferred content of manganese slag is 30-40%, and optimum content is 40%;
Step 2: configure in proportion by granulated blast-furnace slag, gypsum and manganese slag; use wide mouth blanking bin; while wide mouth blanking bin is shaken, granulated blast-furnace slag, manganese slag and gypsum are added shredder, produce high reactivity breeze by vertical mill grinding technical matters.
Vertical mill grinding technical matters produces S95 breeze, and the starting material used are all Liu Gang granulated blast-furnace slag.Have employed multiple exciting agent for S95 breeze and extra material promotes existing breeze activity in testing laboratory, sum up the test done and drawn following several test that can improve the activity of breeze:
Mix the impact of manganese slag on breeze activity, as following table:
As shown in Figure 1, along with the increase of manganese slag incorporation, the activity of breeze increases, but fails to reach S95 breeze Active pharmaceutical, and the price valency of manganese slag is high, and along with the increase of volume, production cost also increases thereupon.
Mix the impact of gypsum on breeze activity, as following table:
As shown in Figure 2, along with the incorporation of gypsum increases, the activity of breeze increases, but effect fails to reach S95 breeze index request, and breeze Standard SO3 content≤4.0%.
Mix the impact of manganese slag on breeze activity, see Fig. 3.
Mix the impact of gypsum on breeze activity, see Fig. 4.
Adopt manganese slag+gypsum to produce breeze as spike, do not need to increase exciting agent and add equipment, save exciting agent and bring cost into; Through inspection, SO
3content Test is stablized, and Activity determination all meets S95 breeze standard-required.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
