Abstract
The invention relates to a big rounded-grain nitrogen potassium chlorine based binary compound fertilizer and a preparation method of the compound fertilizer. Main raw materials of the nitrogen potassium chlorine based binary compound fertilizer are powdery ammonium chloride and powdery potassium chloride, a disk or a drum serve as prilling equipment, a prilling assistant is used for forming the big rounded-grain binary compound fertilizer. The big rounded-grain nitrogen potassium chlorine based binary compound fertilizer is produced, as the prilling and the production are difficult, no similar raw material-shaped nitrogen potassium fertilizer exist in the market at present, and in addition, the fertilizer can meet special requirements for nitrogen and potassium nutrient of region soil containing phosphorus. Compared with an existing manufacture process of the compound fertilizer, the compound fertilizer has the advantages of (1) being low in fertilizer production, (2) being flexible in fertilizer formula, capable of arbitrarily adjusting proportion of the ammonium chloride and the potassium chloride and capable of effectively prilling under effects of the prilling assistant; (3) enabling prilling fertilizers to be high in particle strength and enabling average smashing resisting pressure to be 20-40N; (4) having a wide market; and (5) promoting an additional value of the ammonium chloride and having big profits.
Description
Technical field
The present invention relates to a kind of large round shaped grain shape nitrogen potassium chloro binary compound fertilizer and preparation method, the main raw material of this nitrogen potassium chloro binary compound fertilizer is powdery ammonium chloride and powdery Repone K, adopt disk or drum granulating equipment, utilize granulation aid to make it become large round shaped grain binary compound fertilizer.Make up the blank of this type of fertilizer in the market, meet phosphorous ground region soil to nitrogen, the specific demand of potassium nutrition.
Background technology
Composite fertilizer's quality is various in the market, has diammonium phosphate, the monoammonium phosphate of binary nitrogenous-phosphatic manure, has various chloros, nitro, urine base, sulfenyl nitrogen-phosphorus-potassium Nitrogen, Phosphorus and Potassium.But the binary fertilizer that but there is no nitrogen potassium nutrition, Repone K, ammonium chloride, as a kind of high nutrient simple substance potash fertilizer and simple substance nitrogenous fertilizer, are the indispensable fertilizer varieties of farm crop.
Vast territory and abundant resources in China, the soil characteristic of each region also varies, the phosphorous height of some local soil, this type of soil only needs nitrogen and potassium nutrition, such as Hubei Huang Po, if these local nitrogen phosphorus potassium ternarys of using are fertile, that is exactly a kind of waste, does not also meet the thought of the scientific and reasonable fertilising of China Ministry of Agriculture proposition.
At present, on market, whether there is large round shaped grain binary fertilizer of this type of nitrogen potassium, be mainly because ammonium chloride and Repone K the two all belong to grittiness fertilizer, granulation difficulty, so nitrogen phosphorus potassium unit fertilizer is prepared by adding the better monoammonium phosphate of viscosity by general fertiliser production producer, or composite urea preparation urine base Nitrogen, Phosphorus and Potassium.
In theory, also can mix with powdery ammonium chloride and Repone K, directly use powdered fertilizer, why peasant is unwilling so to have done, and it is bad that reason is exactly powdered fertilizer performance, and fertilising is inconvenient, during granulated fertilizer handling, easily play dirt, long-term storage is very easily lumpd, and is seriously to harden, poor fluidity, during fertilising, be difficult to scatter, cannot realize motor-driven fertilising, simultaneously powdery ammonium chloride and Repone K good water solubility, easily cause the too fast release of nutrient, burn crop to death.
For above-mentioned variety of problems, develop a kind of preparation method of large round shaped grain shape nitrogen potassium chloro binary compound fertilizer, make up the blank of this type of fertilizer in the market, and meet phosphorous soil to nitrogen, the specific demand of potassium nutrition has become the task of top priority.
Summary of the invention
The object of the invention is to make up the blank of this type of fertilizer in the market, meet phosphorous ground region soil to nitrogen, the specific demand of potassium nutrition, overcome because using powdery ammonium chloride and Repone K to mix, directly use powdered fertilizer, cause fertilising inconvenient, during granulated fertilizer handling, easily play dirt, long-term storage is very easily lumpd, and be seriously to harden, poor fluidity, during fertilising, be difficult to scatter, cannot realize motor-driven fertilising, while powdery ammonium chloride and Repone K good water solubility, easily cause the too fast release of nutrient, burn the series of problems such as crop to death, and provide a kind of large round shaped grain shape nitrogen potassium chloro binary compound fertilizer and preparation method, the present invention utilizes existing granulating disc or rotary drum granulator, in ammonium chloride and Repone K, add 5-10 kg/tonne of fertile granulation aid, can complete the preparation of large round shaped grain shape nitrogen potassium chloro binary compound fertilizer, produce granule strength high, fertilizer is being produced, transportation, deposit in process, be difficult for efflorescence.
For achieving the above object, technical scheme of the present invention is:
A kind of large round shaped grain shape nitrogen potassium chloro binary compound fertilizer, it is characterized in that: main raw material is powdery ammonium chloride and powdery Repone K, granulation aid, powdery ammonium chloride and powdery Repone K are mixed, adopt disk or drum granulating equipment, it is 20%-40% solution that granulation aid is mixed with to mass concentration, with atomizing nozzle continuous spraying, on granulation material, make large round shaped grain nitrogen potassium chloro binary compound fertilizer.
The amount that described granulation aid adds is 5-10 ‰ of granulation material total amount.
Described granulation aid, each component by mass percentage, Sumstar 190 20-40%, pre-gelatinized starch 40-60%, wetting agent alkyl glycoside APG 5-20%, each component sum is 100%, and above-mentioned each raw material is mixed and makes granulation aid.
A preparation method for large round shaped grain shape nitrogen potassium chloro binary compound fertilizer, is characterized in that: carry out according to the following steps:
(1) ammonium chloride of powdery is mixed with arbitrary proportion with Repone K; Also can support needs according to difference, allocate a small amount of wilkinite dilution nutrient into;
(2) mixture is put in granulating disc or rotary drum granulator, started granulating equipment;
(3) 5-10 ‰ the granulating agent that accounts for granulation material total amount being mixed with to mass concentration is 20%-40% solution, uses atomizing nozzle continuous spraying on granulation material;
(4) the round shaped grain shape nitrogen potassium chloro binary compound fertilizer particle of making is sent into drying system, be dried;
(5) dried round shaped grain shape nitrogen potassium chloro binary compound fertilizer is entered to screening system, sieve;
(6) qualified particle is packed, defective particle fragmentation enters tablets press as returning charge.
Large the round shaped grain shape nitrogen potassium chloro binary compound fertilizer that utilizes the present invention to make, the advantage of its more existing compound fertilizer production technology:
(1) fertiliser production cost is low.
(2) fertilizer formula is flexible, can adjust arbitrarily ammonium chloride and Repone K ratio, under the effect of granulation aid, and equal effective granulating.
(3) the fertiliser granulates intensity of producing is high, average anti-crushing pressure 20-40N.
