Abstract
The present invention belongs to an improvement of the existing manufacturing process of cement in a series of sulfur (iron) aluminate, particularly to relates a manufacturing process of the cement clinker of the sulfur (iron) aluminate with the utilization of industrial waste. The present invention has the technical scheme that expensive natural gypsum is replaced by ardealite as the industrial waste, and cement raw material is prepared by using iron powder or the tailing powder of iron ore as an additive; then, the cement raw material is calcined for preparing the cement clinker of the sulfur (iron) aluminate with qualified physical characteristics and chemical characteristics. The present invention provides a foundation for preparing the serial products of the cement of the sulfur (iron) aluminate with various characteristics, and realizing high quality and low price; simultaneously, the present invention provides a new way for solving industrial pollution.
Description
Technical field
The present invention relates to additional or improvement, particularly to producing the improvement of grog operation to existing sulphur (iron) aluminate cement technology.
Background technology
Sulplo-aluminate and ferro-aluminate cement all do not have the difference of essence on from the formula constituent to the complete processing.Being calcium sulphoaluminate that main cement is called sulphur aluminium cement traditionally, then being called iron aluminium cement based on the cement of iron calcium aluminate, promptly is also not have obvious or strict boundary in the standard that country is correlated with.And the approximation that shows on its production technology, can think in fact that then sulphur aluminium cement and iron aluminium cement series are included within the common technical field.Below just abbreviate sulphur (iron) aluminate cement as.Comprise fast gravity die sulphur (iron) aluminate cement in this series cement, low basicity type sulphur (iron) acid salt cement and expanded polystyrene veneer sulphur (iron) acid salt cement.All to pass through following three operations in the technology of its production, each raw materials by weight be combined raw material pulverize, grind; The raw material calcining is grog; Be that base-material is allocated an amount of plaster of paris into by its final technical requirements or other filling modifying agent carries out the cement that weight percent is mixed, grinding becomes different size to the standard fineness with the cement clinker of making again.In the grog production phase of sulphur (iron) aluminate cement, main raw material is Wingdale, alumina and the plaster of paris.The cost of material of the plaster of paris is relatively expensive, high-quality alumina resource shortage and when using and nonessential limiting quantity.So special cement is on the high side, but and there is a bigger room for improvement.So how to utilize existing industrial waste or replace natural matter in large quantities, not still to the saving of resource, and can under the prerequisite of ensuring the quality of products, reduce production costs greatly, can solve the problem of environmental pollution of industrial waste simultaneously again, be the outstanding research topic of the sharp enterprise of benefiting the nation and the people.
Summary of the invention
Key of the present invention is will partly replace the plaster of paris with industrial residue phosphogypsum in the production technique of sulphur (iron) aluminate cement grog, prepares raw material with iron powder or iron ore powder (mainly being the mine tailing that sifts out when selecting iron ore) as weighting agent.Proportioning by repeated multiple times and orthogonal test are selected rational component mix proportion scheme and are made the finished product grog by corresponding calcination process and detect, in the hope of reaching the materialization standard of cement intermediates.For having realized to the special Success in Experiment of colloidal phosphogypsum dehydration the phosphogypsum dehydration procedure, the standard water-content when phosphogypsum water content 6.5% can reach the preparation raw material after dewatering is not so influence the quality of raw material component.The iron powder that is added mainly is an oxide composition, the CHARACTERISTICS OF TAILINGS SAND of iron ore adds as increasing iron aluminium phase composition, through the test many times and the detection contrast of grog physico-chemical property selected finally utilize the industrial waste phosphogypsum and add iron sand or iron ore tail sand after the proportioning composition range of raw material be:
Wingdale: 46-52%
Alumina: 16-36%
Phosphogypsum: 0-16%
The plaster of paris: 0-16%
Iron sand or iron ore: 0-10%
Further specify below in conjunction with the embodiment that provides and the objective of the invention is how to realize.
Embodiment:
Industrial waste when phosphogypsum is production phosphoric acid, water content are up to more than 20%.Utilize furnace drying method can cause the mass consumption of the energy,, water content is dropped to below 6.5%, and then be mixed, grind, grind by weight participating in as the raw material integral part so take to remove part moisture content with 100 ℃ of low temperature of heating.
The alumina that uses in the raw material is a bauxitic clay, red bauxite or mixture between the two all can, need to decide according to the purposes or the product design demand of specific product.
The component of phosphogypsum can replace with fluorgypsum, and the concrete operation of handling is identical with processing condition.
Its calcining process and common process there is no any difference, press prescription (or following examples) proportioning, can burn qualified sulphur (iron) aluminate cement grog after the proportioning, with grog again with the modifying material proportioning after grinding can be made into qualified sulphur (iron) aluminate cement grog, with grog again with the modifying material proportioning after grinding can make sulphur (iron) the aluminate cement product of various performances.
Embodiment:
Embodiment is as follows: (weight percent)
| Embodiment | Wingdale | Phosphogypsum | Alumina | The plaster of paris | The tail iron ore |
| 1 | 46 | 16 | 38 | 0 | 0 |
| 2 | 48 | 10 | 30 | 6 | 6 |
| 3 | 50 | 6 | 26 | 10 | 8 |
| 4 | 52 | 0 | 16 | 16 | 16 |
Can calcine out the grog that is appropriate to not show characteristic sulphur (iron) aluminate cement by the given prescription of following examples, allot according to this little add to be adjusted to add in the grog grinding step join different modified feedstocks and can make soon hard, expand, the cement of sulphur of different nature (iron) aluminate serial such as low alkali.
