Abstract
It is environmental protection; energy-saving and emission-reduction; white portland cement clinker is produced as raw material by the use of industrial residue lithium slag, completely instead of aluminium ore, with lime stone, silica, a small amount of fluorite; mix according to certain ratio; after grinding, heating and calcining makes the Fe2O3 contents of clinker be less than 0.45%; after over-quenching, it is possible to which production production whiteness reaches more than 84 degree of white portland cement clinker.The incorporation of lithium slag can carry out burdening calculation acquisition according to the chemical composition of lime stone, silica and fluorite, Fe2O3 contents in major control clinker will be less than 0.45% or so, after over-quenching, ensure that the whiteness of clinker reaches more than 84 degree, other chemical compositions of clinker are adjusted according to calcining needs, the incorporation of lithium slag needs according to dispensing and calcining needs are adjusted, and general scope is in 0.04%----15% or so.
Description
Technical field
The production field of white portland cement clinker.At present, the raw material of white portland cement clinker is produced substantially all
It is natural material, natural material is fewer and feweri, and industrial residue is more and more, for the environment for reducing industrial residue is dirty
Dye, it is also possible to reach the purpose of energy-saving and emission-reduction, develops one kind and makees the white silicon of raw material production using industrial residue lithium slag
The method of acid salt cement clinker.
Background technology
Waste residue --- -- the lithium slag of the lithium salts factory in county of Sichuan Shehong is a lot, and the Fe2O3 contents of lithium slag are very low, can be as original
Material, instead of aluminium ore, produces white portland cement clinker.The raw material of production white cement is substantially natural material at present,
Natural material is fewer and feweri, and industrial residue is more and more, to reduce the environmental pollution of industrial residue, it is also possible to
The purpose of energy-saving and emission-reduction is reached, a kind of utilization industrial residue is developed and is made the method that raw material produce white cement clinker.
The content of the invention
By the use of industrial residue lithium slag as raw material, completely instead of aluminium ore, and lime stone, silica, a small amount of fluorite, according to one
Fixed ratio mixing, after grinding, heating and calcining makes the Fe2O3 contents of clinker be less than 0.45%, it is possible to produce whiteness and reach
More than 84 degree of white portland cement clinker, Ju Ti Pei Fang and result are as follows：
Claims (2)
1. by the use of industrial residue lithium slag as raw material, completely instead of aluminium ore, and lime stone, silica, a small amount of fluorite, according to certain
Ratio mixing, after grinding, heating and calcining, make clinker Fe2O3 contents be less than 0.45%, it is possible to production production whiteness reach
White portland cement clinker to more than 84 degree.
2. can also partly substitute aluminium ore, and lime stone, silica, a small amount of fluorite mix according to certain ratio, through grinding after,
Heating and calcining, makes the Fe2O3 contents of clinker be less than 0.45%, it is possible to which production production whiteness reaches more than 84 degree of white silicic acid
Salt cement clinker.
