Description
Technical field
The invention belongs to building material technical field, particularly relate to a kind of cement clinker that utilizes multiple industrial residue to produce.
Background technology
It is the raw material calcining of preparing burden that traditional cement clinker adopts the natural Mineral resources such as Wingdale, clay, silica sand, iron ore, gypsum, fluorite, coal and the energy, has not only wasted a large amount of natural resource and the energy, and has discharged a large amount of CO
2And other obnoxious flavour, contaminate environment is serious.At present, had and utilized magnesium metal reduction slag or industrial residues such as calcium carbide mud or dicyandiamide dreg to substitute the technology that batchings such as part or all of Wingdale and clay, iron ore are made the raw material calcination of cement clinker separately, but be limited by the fluctuation of material chemical component and the restriction of cement clinker controlling of production process parameter, its waste residue utilization amount is little, quality is single, energy-conservation, reduce discharging, consumption reduction do not reach best effect as yet, it is bigger to apply difficulty.
Summary of the invention
Purpose of the present invention just is to overcome the defective of above-mentioned prior art, and a kind of cement clinker of widely applying industrial residue to produce is provided.
The present invention is achieved through the following technical solutions:
A kind of cement clinker that utilizes multiple industrial residue to produce, it is characterized in that this cement clinker stone flour, magnesium metal reduction slag, lime slag or calcium carbide mud or dicyandiamide dreg, flyash or coal gangue reach and adopt the calcining process calcining to form after sulfate slag composite optimization batching is made raw material;
Described calcining process is the novel dry-process rotary kiln calcining process, and its raw material composition is counted with weight proportion:
Stone flour 40~80%,
Magnesium metal reduction slag 5~25%,
Lime slag or calcium carbide mud or dicyandiamide dreg 5~30%,
Flyash 2~10%,
Sulfate slag 0.5~3%;
Described calcining process is a shaft kiln calcination technology, and its raw material composition is counted with weight proportion:
Stone flour 20~70%,
Magnesium metal reduction slag 5~40%,
Lime slag or calcium carbide mud or dicyandiamide dreg 5~30%,
Coal gangue 1~10%,

Fluorite 0.8~1.2%,
Hard coal 6~10%;
Described stone flour is native crack soil and the limestone fines mixture that sieves out with limestone crushing of mountain skin that the limestone mine exploitation is peeled off.
The present invention fully utilizes multiple industrial residue producing cement grog, the waste residue utilization amount is big, can save a large amount of natural resource and the energy, and waste residue through composite optimization batching back in the burning clinker of cement process saving standard coal consumption reduce a large amount of CO simultaneously more than 20%
2And other discharge of harmful gases, clinker burning speeds up, and is energy-conservation, reduce discharging, and consumption reduction, environment protecting is obvious, experiment showed, that single machine yield and production efficiency improve, and 28 days compressive strength rate traditional modes of production of grog clinker strength improves more than the 5MPa.
