Abstract
The invention discloses a kind of little particle clinker, directly it is incorporated in proportion in raw material using controlling agent as a kind of starting components, calcined using new type dry kiln, have the clinker particles that big apperance is in thin pearl in the clinker of calcining out, wherein apparent grain diameter 0.1 3.0 millimeters of little particle clinker in whole clinkers accounting more than 50%.The controlling agent is selected from the natural gypsum, anhydrite, fluor-apatite, Copper Slag, slag, cadmia, nickel slag, phosphorus slag, flyash, or combinations thereof, than for its volume scope of cement slurry 0.1% 5%.Cement clinker mineral structure provided by the invention has low energy consumption, low-carbon, high-strength and other effects compared with Portland cement.
Description
Technical field
The present invention relates to a kind of little particle clinker.
Background technology
Cement industry is resource, the industry of energy dependent form basic raw material.China is manufacture of cement the biggest in the world and disappeared
Fei Guo, China's cement output in 2012 account for the 60% of world wide production, and manufacture of cement consumes substantial amounts of lime stone and clay etc. can not
Renewable natural resources, and substantial amounts of coal electricity equal energy source is consumed, while give off substantial amounts of carbon dioxide, sulfur dioxide and nitrogen oxidation
The waste gas such as compound.The huge energy, resource consumption make the mineral resources in China can't bear the heavy load, and substantial amounts of waste gas discharge exacerbates temperature
The generation of room effect and acid rain, seriously pollutes environment.The main update for paying attention to cement technology equipment domestic at present, less
Pay attention to the research and development to cement material in itself, however it remains sinter leaching temperature is high（1450℃）, product carbon emission is high
Phenomenon.And raising cement output is reached by the cement industry development model of expanding, to meet the needs of the development of the national economy,
The further surplus of cement production capacity will be caused, production scale further expands, and product homogeneity aggravation, market is mainly by cost
To compete, this will bring totally unfavorable influence to the sustainable development of the society and economy in China.
To realize the energy-saving and environmental protection in cement production process, consumption reduction, two kinds of technical schemes of generally use：First, by changing
Enter production technology and equipment, regulate and control the burn-ability and grindability of raw material, or rationally fill industrial residue；Second, research
Develop energy-saving new types of Cernent system.At present, the former has been had made great progress, and slag, flyash are filled such as in cement
Deng admixture, or Modern New dry production technology and efficient grinding technology are used, but the technology has gone to bottleneck, thinks to break through again
It is highly difficult.And the latter has turned into the study hotspot of current cement field, its right popularization and application are by conventional cement industry thinking office
Limit, it is impossible to universal large-scale use.
The content of the invention
The defects of in order to overcome modern cement industry high energy consumption, maximum discharge, the invention provides a kind of little particle cement is ripe
Material, the clinker have low energy consumption, low-carbon, high-strength and other effects.
The present invention is directly incorporated in proportion in raw material using controlling agent as a kind of starting components, using new type dry kiln
Calcined, the clinker for calcining out, more than 50% particle diameter is less than 3.0 millimeters.
The definition of controlling agent：Refer to coordinate a kind of additive of the invention that forms little particle clinker and must add, mainly
Function is increase clinker liquid phase surface tension, controls clinker size.
Described controlling agent be selected from the natural gypsum, anhydrite, fluor-apatite, Copper Slag, slag, cadmia, nickel slag, phosphorus slag,
Flyash, or combinations thereof, than for raw material its volume scopes in 0.1%-5%.
The little particle clinker burnt out by the inventive method sinters in order, and free calcium oxide is low.
The difference of the present invention and conventional cement technique：
1st, with the difference of blown sands material
Blown sands material is mainly the big lattice clinker formed during clinker burning, such un-sintered balling-up of clinker, is easily formed
Dust material, the more normal sintered clinker of intensity is relatively low, and grindability is poor, burns till high energy consumption.
The little particle clinker formed using present invention calcining, in addition to apparent size is close with blown sands material, remaining performance is complete
It is complete different, have intensity higher, burn till the lower characteristic of energy consumption.
2nd, clinker liquid phase surface tension
The theory of conventional cement production thinks that clinker liquid phase surface tension is smaller, and clinker size is bigger, the life of in general cement
Also control clinker liquid phase surface tension is small as far as possible for production.And the present invention is on the contrary, the addition of controlling agent causes the liquid phase table of clinker
Face tension force is higher, in centrifugal force（Cement kiln, which rotates, to be produced）In the presence of, the clinker apparent size of formation is smaller.
Compared with prior art, the advantage of the invention is that：
1st, the particle size of common portland cement clinker is concentrated mainly on 5-50 millimeters, and the portland cement invented is ripe
Material, its particle size are concentrated mainly on 0.1-3 millimeters, and little particle clinker can reduce grinding stage energy consumption, and energy consumption drop ratio reaches 5%
More than；
2nd, 28 days compression strength of common portland cement clinker is prepared probably in 55-58MPa scopes by this technology
Little particle Portland clinker, its 28 days compression strength are up to 58-70MPa.
