Description
Technical field
The present invention relates to a kind of blended material of producing cement and preparation method thereof that is used to.
Background technology
Along with the development of overrunning of Cement industry, cement market is in the serious present situation that supply exceed demand at present, and the main means of cost competition becoming cement production enterprise competition also become the emphasis of cement production enterprise research of technique and reduce production costs.Blended material is one of important starting material of Cement industry, both can be used to improve cement performance, and production different varieties cement also can increase output, reduces production costs.Therefore, seeking blended material of high quality and at a reasonable price is the emphasis of the technological updating of enterprises and the work that enhances the competitiveness.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of blended material that is used to produce cement, characteristics such as this blended material has that cost is low, steady quality, environment protection significance are outstanding.
Another technical problem to be solved by this invention is: provide the preparation method of above-mentioned blended material, this preparation method's simple possible.
The present invention solves the technical scheme that its technical problem adopts:
A kind of blended material that is used to produce cement, its main raw material are waste ceramic.
Above-mentioned blended material is made up of following weight percentages:
Waste ceramic 90-99%
Natural volcanic ash is or/and graphite 1-10%.
Above-mentioned blended material is made up of following weight percentages:
Waste ceramic 90-99%
Graphite 0.2-1%
The natural volcanic ash surplus.
In above-mentioned blended material, adding natural volcanic ash in waste ceramic mainly is the color of improving prepared blended material.
Adding graphite, mainly is grindability and the color of improving blended material, makes blended material have the grinding aid effect simultaneously, and the optimum range of interpolation is at 0.2-1%.
A kind of raw material is the preparation method of the blended material of waste ceramic only, and it comprises the steps:
A. with the waste ceramic surface washing and dry,
B. use crusher in crushing;
Waste ceramic dried the weight content of back moisture content less than 2.0% during above-mentioned A went on foot.
The particle diameter of above-mentioned B waste ceramic after the fragmentation in the step is less than 20mm.
A kind of raw material is waste ceramic, natural volcanic ash or/and the preparation method of the blended material of graphite, and it comprises the steps:
A. waste ceramic surface washing and drying;
B. with crusher with the waste ceramic fragmentation;
C. natural volcanic ash is dried;
D. above-mentioned raw materials by weight percent is put into mixing machine and mixed, promptly get blended material.
Waste ceramic dried the weight content of back moisture content less than 2.0% during above-mentioned A went on foot.
The particle diameter of above-mentioned B waste ceramic after the fragmentation in the step is less than 20mm.
Above-mentioned C dries the weight content of back moisture content less than 2.0% in natural volcano in the step.
Beneficial effect of the present invention:
1. China is ceramic industry big country, the amount of waste ceramic is very big, the processing of waste ceramic is the ceramic industry urgent problem at present, cement production enterprise uses waste ceramic need buy hardly, only need freight charges to get final product, so both solve the environmental problem of ceramic industry, can solve the cheap starting material of Cement industry blended material again.
2. waste ceramic involved in the present invention comprises the finished product waste ceramic of snitaryware, architectural pottery, its essential mineral consists of silicate minerals, active good, with it is that the blended material of main raw material can be applied among ordinary Portland cement, composite Portland cement, Portland pozzolana cement, masonry cement produce, and can reduce the Cement Production cost greatly.
3. as after adding a spot of graphite in the blended material, can change the surface tension of broken pottery, play the grinding aid effect, simultaneously the color of adjustable blended material.
4. quality index of the present invention meets national standard.
5. blended material preparation method of the present invention is simple.
