Abstract
A method for producing a particulate ammonium sulfate product with an inorganic binder, comprising: (1) one of diammonium phosphate or monoammonium phosphate or a mixture of diammonium phosphate or monoammonium phosphate and magnesium sulfate monohydrate or magnesium sulfate heptahydrate is selected as an inorganic binder for producing ammonium sulfate granules, and the inorganic binder is crushed for later use; (2) crushing the crystal ammonium sulfate; (3) uniformly mixing the crushed crystal ammonium sulfate and the crushed inorganic binder according to the proportion of the inorganic binder and the ammonium sulfate, adding the mixture into a granulator, and granulating by using medium-pressure steam to obtain a semi-finished product; (4) drying the semi-finished product; (5) and screening the dried finished product, and packaging the product after the product is qualified. The method has the following advantages: the process is simple and convenient to operate; secondly, the binder is easy to obtain, the mass fraction of the product nutrients is more than 90%, the granularity is uniform, and the strength is suitable for large-scale mechanized operation; the binder is freely proportioned according to the granulation requirement, and can meet the requirement of large-scale mechanical production. Is suitable for being popularized and used in the production of compound fertilizers.
Description
Technical field
The present invention relates to the chemical fertilizer product, further, relate to the production of ammonium sulfate, relate in particular to the method for producing ammonium sulphate grain with mineral binder bond.
Background technology
Along with development of market economy, large-scale agricultural mechanization development is more and more fast.In recent years, granulated fertilizer has received client's favor, and its price is far above the fertilizer of traditional form.As the nitrogenous fertilizer ammonium sulfate that goes on the market the earliest, present crystal habit can't satisfy mechanization of agriculture fertilising requirement.
In the existing one Chinese patent application part, disclose a kind of preparation method of large-particle ammonium sulfate, but failed to be widelyd popularize for the CN1051711 of japanese publication number; CN88102293A number of Holland application discloses in grain fluidized bed granulation contains the granulated fertilizer of urea and ammonium sulfate with production method; But because it contains urea concentration up to 70%～99.9%; Reduce the content of ammonium sulfate own, changed its component, especially reduced the content of S.It is the method for preparing ammonium sulfate and fertilizer of carbon dioxide with the gypsum that No. 00104473.7 of Ningxia Zhang Minqian application then discloses a kind of small nitrogenous fertilizer plant; Mention the direct oven dry of the lime carbonate that will contain ammonium sulfate and produce fertilizer of carbon dioxide, but this method can not be used for ammonium sulphate grain production with adhesive complex.Still the no-trump organic binder bond is used for the report that ammonium sulphate grain is produced at present.
Summary of the invention
The object of the present invention is to provide a kind of method of producing ammonium sulphate grain products, can make agricultural crystal ammonium sulfate bonding granulating, thereby search out a kind of new production approach for ammonium sulphate grain with mineral binder bond.
For with the crystal ammonium sulfate granulating on the market, satisfy the mechanize requirement, the contriver is through long-term exploratory development; Chosen and to have made the granulated mineral binder bond of crystal ammonium sulfate, and can guarantee the character of ammonium sulfate itself, do not changed the component concentration of ammonium sulfate; The ammonium sulfate product uniform particles of being produced; Granularity is accounting for total amount more than 90% about 1-5mm, more than the intensity 12N, makes it can satisfy fully the requirement of big machineryization.
The method with mineral binder bond production large-particle ammonium sulfate product that the contriver provides may further comprise the steps:
(1) select a kind of in diammonium phosphate or the monoammonium phosphate for use, or the mixture of diammonium phosphate or monoammonium phosphate and magnesium sulfate monohydrate or MAGNESIUM SULPHATE HEPTAHYDRATE 99.5 is as being used for the mineral binder bond that ammonium sulphate grain is produced, it is subsequent use to pulverize the back;
(2) crystal ammonium sulfate is pulverized;
(3) the crystal ammonium sulfate after the pulverizing and the mineral binder bond of pulverizing mix in proportion by mineral binder bond and ammonium sulfate, add in the tablets press, carry out granulation with MP steam, obtain work in-process;
(4) work in-process are carried out drying;
(5) dried product sieves according to moisture content index and granularity requirements, through being up to the standards, choosing particles with suitable particle at last and packs as product.
In the above-mentioned the first step, said mineral binder bond is pulverized the back granularity and is controlled at 20～200 orders; The blending ratio of said diammonium phosphate or monoammonium phosphate and magnesium sulfate monohydrate or MAGNESIUM SULPHATE HEPTAHYDRATE 99.5 is 1: 1～4: 1.
In above-mentioned second step, said crystal ammonium sulfate is pulverized the back granularity and is controlled between 20～200 orders.
In above-mentioned the 3rd step, the additional proportion of said mineral binder bond is controlled between 1%～10%, guarantees the composition of ammonium sulfate product itself; Control control prilling temperature is between 60 ℃～150 ℃.
In above-mentioned the 4th step, said drying process is according to the hot blast capacity load, chooses one section drying or two-stage drying, and used drying temperature is 220 ℃～280 ℃ for one section, and two sections is 180 ℃～240 ℃.
In above-mentioned the 5th step, the granularity of said finished product is 1～5mm.
Method of the present invention is compared with known method of production, has the following advantages: 1. production technique is simple, is convenient to operation; 2. sticker is easy to get, and the massfraction of product nutrient is more than 90%, epigranular, and intensity is fit to the big machinery operation; 3. sticker is according to the granulating situation, and suitable free proportioning can satisfy big machinery production.This method suits in production of compound fertilizer, generally to promote, and can improve product market competitiveness.
Embodiment
Below further specify the present invention through embodiment:
Instance 1 single mineral binder bond is produced ammonium sulphate grain
Select for use diammonium phosphate as mineral binder bond, it is subsequent use to be crushed to 20～200 orders; (effective constituent is N:20.4%, S:23.58%, H with the ammonia sulfate crystal of≤2mm
2O:0.8%) be crushed to 20～200 orders through kibbler; According to the diammonium phosphate and the ratio of ammonium sulfate is to mix at 5: 95, gets in the tablets press, through MP steam spraying carrying out granulation, 120 ℃～160 ℃ of prilling temperatures; Through two sections drying machine dryings, one section exsiccant temperature is at 220 ℃～280 ℃, and the two-stage drying temperature is carried out drying at 180 ℃～240 ℃; Cooling back is with the sieve apparatus screening, and the particle of choosing granularity and be 1～5mm is an ammonium sulfate product, and through being up to the standards, packing is dispatched from the factory.
