Abstract
The invention discloses a cement manufacturing technology which is used for processing raw materials into cement. The cement manufacturing technology comprises the steps that the raw materials are provided and subjected to stirring and preheating decomposition, wherein the preheating temperature ranges from 800 DEG C to 1,200 DEG C, and stirring is continuously operated; a catalyst is added, the raw materials further react, the temperature is increased, and meanwhile spray treatment is conducted on the raw materials; the raw materials are crushed and prehomogenized, and meanwhile the raw materials are prepared and homogenized; preheating decomposition is conducted again, wherein the preheating temperature ranges from 1,000 DEG C to 1,500 DEG C; the raw materials are fired to be in a liquid state, and after the temperature is lowered, the raw materials are coagulated; the coagulated raw materials are ground, and the cement is obtained. In this way, the crushing difficulty is reduced, the processing time is shortened, and the quality of the processed product can be guaranteed.
Description
[technical field]
The present invention relates to a kind of manufacturing process of cement, the manufacturing process of espespecially a kind of efficient cement.
[background technology]
In the production process of industry cement, because its raw material is limestone, clay, iron ore and coal etc., and cement is uniform
Powder, therefore need raw material is crushed, wherein, particularly limestone, it is to produce the maximum raw material of cement consumption,
Granularity after exploitation is larger, and hardness is higher, and according to statistics, often producing one ton of cement at least needs three tons of raw materials of grinding, grinding consumption
Power account for more than the 60% of full factory power, therefore, reasonable selection milling equipment and technological process, Optimizing Process Parameters, correctly
Operation, controls operation system, and the quality and reducing energy consumption ensureing product is significant, otherwise, not only cost increase, and
Difficult quality guarantee, as to how efficient production cement, is also the difficult problem that industry compares headache at present.
Therefore, it is necessary to design a kind of manufacturing process of good cement, to overcome the problems referred to above.
[content of the invention]
For background technology problem encountered, it is an object of the invention to provide a kind of pre- in advance thermal decomposition is to reduce broken hardly possible
The manufacturing process of the cement of degree.
For achieving the above object, the present invention is using following technological means:
A kind of manufacturing process of cement, in order to be processed to raw material forming cement, it includes providing raw material, and raw material is stirred
Mix and stir pre- thermal decomposition, between the temperature of preheating is 800 degree to 1200 degree, stir as working continuously；Add catalyst, raw material enters one
Step reacts, and temperature rises, and carries out spraying treatment to raw material simultaneously；Raw material is carried out with broken and pre- homogenizing, meanwhile, raw material
Preparation homogenizing；Thermally decompose in advance again, between the temperature of preheating is 1000 degree to 1500 degree；Raw material is fired, raw material is liquid
State, after temperature drop, raw material condenses；Grinding is carried out to the raw material condensing, makes cement.
Further, raw material is that limestone, clay, iron ore and coal form.
Further, catalyst is potassium permanganate.
Further, persistently spray in pre- thermal decomposition process again.
Compared with prior art, the method have the advantages that
In the manufacturing process of above-mentioned cement, before and after raw material is carried out with broken and pre- homogenizing, all adopt stirring respectively and preheat
Decompose, and the temperature preheating, between 800 degree to 1200 degree, stirring as working continuously, adds catalyst, raw material occurs further
Reaction, temperature rises, and carries out spraying treatment to raw material simultaneously, thermally decomposes in advance again afterwards, and the temperature of preheating is for 1000 degree extremely
Between 1500 degree, so, reduce the time of broken difficulty and processing, and can ensure that the quality of converted productss.
[brief description]
Fig. 1 is the schematic diagram of the manufacturing process of cement of the present invention.
[specific embodiment]
For ease of being better understood from the purpose of the present invention, structure, feature and effect etc., in conjunction with the drawings and specific embodiments
The invention will be further described.
Refer to Fig. 1, a kind of manufacturing process of cement, in order to be processed to raw material forming cement, raw material is limestone,
Clay, iron ore and coal composition, the step of the manufacturing process of cement includes following: provides raw material, raw material is stirred and in advance
Thermal decomposition, between the temperature of preheating is 800 degree to 1200 degree, stirs as working continuously, by limestone, clay, iron ore and coal
Carry out full and uniform stirring so that the heating temperature of above-mentioned each raw material can be as far as possible identical；Add catalyst, catalyst is height
Potassium manganate, raw material reacts further, and temperature rises, and certainly, can also be in other embodiments, other catalyst,
Here the effect adding catalyst is exactly in order to so that not passing through the heating of external force, as long as raw material and catalyst merge one
Rise it is possible to there is heat together, reduce the input of cost, and spraying treatment is carried out so that cement is unlikely to raw material simultaneously
Excessively high temperature and burn because aforesaid operations are all to carry out in the space of sealing, workman is difficult to observe；Raw material is carried out broken and
Pre- homogenizing, meanwhile, homogenizing prepared by raw material；Thermally decompose in advance again, between the temperature of preheating is 1000 degree to 1500 degree, and again
Pre- thermal decomposition process in persistently spray, the effect herein sprayed is with aforementioned；Raw material is fired, raw material is liquid, treats temperature
After degree declines, raw material condenses；Grinding is carried out to the raw material condensing, makes cement.
In the manufacturing process of above-mentioned cement, before and after raw material is carried out with broken and pre- homogenizing, all adopt stirring respectively and preheat
Decompose, and the temperature preheating, between 800 degree to 1200 degree, stirring as working continuously, adds catalyst, raw material occurs further
Reaction, temperature rises, and carries out spraying treatment to raw material simultaneously, thermally decomposes in advance again afterwards, and the temperature of preheating is for 1000 degree extremely
Between 1500 degree, so, reduce the time of broken difficulty and processing, and can ensure that the quality of converted productss.
The explanation of detailed description above only the preferred embodiments of the invention, non-the scope of the claims therefore limiting to the present invention,
So, all equivalence techniques changes done with this creation description and diagramatic content, it is both contained in the scope of the claims of the present invention
Interior.
