Description
Technical field
The present invention relates to field of compound fertilizer production.
Background technology
At present, high-nitrogen compound fertilizer uses extensively, can be used for field crop, cash crop or melon or fruit type crops, be mainly used in sowing time and lift seedlings the phase, the nutrient of plant growth initial stage abundance can be supplied to, especially nitrogen, it is the formula used in a large number in initial planting at present, but because in formula, amount of urea is high, often occur that production system balling ratio is low aborning, the situations such as production system is unstable, in addition its usage period is generally at high-temperature high humidity season, high-temperature high humidity season is produced high nitrogen formula and is easily caused the production environment moisture absorption, thus affect the stable of Working environment and production system, therefore it is low to produce high-nitrogen compound fertilizer balling ratio at high temperature season, production system instability is a difficult problem always.
Summary of the invention
Object of the present invention is exactly low for producing high-nitrogen compound fertilizer balling ratio at high temperature season, the deficiency of production system instability, and provides a kind of high-nitrogen compound fertilizer and complete processing of favourable raising balling ratio.
Raw material of the present invention is urea, ammonium chloride, ammonium sulfate, monoammonium phosphate, Repone K, potassium sulfate, filler and binding agent, and its parts by weight of raw materials proportioning is:
Urea 35-60 ammonium chloride 10-20
Monoammonium phosphate 10-20 Repone K 0-20
Potassium sulfate 0-20 filler 5-10
cassava modified starch0.5-0.8.
Its parts by weight of raw materials optimum proportioning is:
Urea 28.3 ammonium chloride 21.7 monoammonium phosphate 34.5
Repone K 8.1 bicarbonate of ammonia 2.4 carclazyte 4.2
cassava modified starch0.8.
Production craft step is as follows:
A, by various raw material through grinding, the preprocessing process such as dry is treated to the uniform powder material of fineness, then pulverulent material is fed in tablets press machine respectively and carries out granulation, in tablets press, add steam simultaneously, material is granule balling-up in tablets press, after tablets press outlet, send into dryer by belt; Its controlling of production process is:
Raw material feed rate: 10-25 ton/hour
Prilling section vapor temperature: 100-110 DEG C
Prilling section vapor pressure: 0.8-1.2Mpa
Dry workshop section's inlet air temperature: 100-150 DEG C
Dry workshop section's outlet air temperature: 54-56 DEG C
Dry workshop section's inlet feed temperature: 60-70 DEG C
Dry workshop section's outlet mass temperatures: 50-60 DEG C;
B, material carry out drying through dryer, and it is shaping that the material after oven dry carries out cooling through cooler.
Filler is wilkinite, carclazyte or Attapulgite powder.
Advantage of the present invention is: present invention improves over the existing high nitrogen formula that generally uses and drum granulating production technique, even if make at high-temperature high humidity season, also high nitrogen high-nitrogen compound fertilizer can normally be produced, balling ratio improves 30-50%, finished particle intensity improves 10-20%, production system is stablized, good product quality.

By above-mentioned each parts by weight of raw materials ratio, operate as follows:
The first step: by various starting material through grinding, the preprocessing process such as dry is treated to the uniform powder material of fineness;
Second step: various starting material are sent into rotary drum granulator through automatic metering system by belt according to predetermined proportion, in tablets press, add steam, material is granule balling-up in tablets press simultaneously, after tablets press outlet, send into dryer by belt;
3rd step: material carries out drying and secondary balling-up through dryer, and the material after oven dry is lowered the temperature through cooler;
4th step: cooled material sieves through thick vibratory screening apparatus, thin vibratory screening apparatus successively, the excessive particle of screening particle diameter is out sent tablets press back to by belt and is carried out secondary granulation after crusher in crushing, and the particle that particle diameter is too small and powder are directly sent tablets press back to by belt and carried out granulation again;
5th step: the work in-process that obtain carry out coating through coating workshop section after screening, then be sent to packaging post by belt and pack.
6th step: the finished product after packaging divides heap stock by formula and kind.
Its controlling of production process is:
Raw material feed rate: 20 tons/hour
Prilling section vapor temperature: 105 DEG C
Prilling section vapor pressure: 1Mpa

Run under identical technic index by above-mentioned 5 embodiments, detect balling ratio and finished particle intensity, result is as following table:
| Formula | Formula one | Formula two | Formula three | Formula four | Formula five |
| Balling ratio | 40~50 | 70~75 | 90~95 | 55~60 | 70~75 |
| Granule strength | 8~12N | 10~15N | 10~18N | 8~13N | 8~15N |
As can be seen from result, owing to adopting novel binders
cassava modified starch (is the powder that cassava dehydrates after starch isolation.Manufacturer: Guangxi State Farms Mingyang Biochemical Group, Inc. produces)and new formulation, system balling ratio can bring up to 90 ~ 95% by initial 40 ~ 50%, finished particle intensity can bring up to 10 ~ 18N by 8 initial ~ 12N, simultaneously due to the raising of balling ratio, the urea circulated in system reduces, the situation of production system easy moisture absorption because urea content is high is greatly improved, and both ensure that the stable of production system, has also solved the moisture issues of production environment.
